[00:00:22] <Elvanor> remember that my use case is very specific, most paypal implementations dont need what I need

[00:00:24] <yobo2> it seems unlikely that youre stumbling upon a major flaw in paypal's ipn system. are you sure there's not something else that you may have overlooked? some way to assume / configure certain character encodings?

[00:00:28] <yobo2> ah

[00:00:58] *** monestri has joined ##java

[00:01:02] <zrunn> Elvanor, either write a proxy or a Filter that changes the stream to what you need

[00:01:07] <yobo2> well i missed your original problem (wasnt in here) and dont know what a typical use case is so i might be wrong about that then.

[00:01:14] <Elvanor> you are wrong :)

[00:01:28] <t3mp3st_> can someone recommend a short yet comprehensive tutorial on writing javadoc? I really have no clue about how to do it and I really need to start documenting my code :(

[00:01:28] <Elvanor> probably less than 0.05% of paypal implementations have my problem

[00:01:40] <yobo2> can you hack it and write a servlet that reencodes it, and have that post a new http request to another servlet?

[00:01:44] <Elvanor> zrunn: a Filter that changes the stream is what I am trying to do

[00:01:49] <poseidon> If I have a class Foo { private class Bar {} }  and I have a method myFoo.getBar() which returns a new bar object.  that Bar object can access myFoo's private propertys right?

[00:01:53] *** bas-i has joined ##java

[00:02:00] <Elvanor> By the way: apparently the forward() in a filter just made the request disappear

[00:02:23] <Elvanor> yobo2: would be a possible solution yes

[00:02:37] <zrunn> Elvanor you can easily find examples on how to change a stream with a Filter on Google.. anyway good luck

[00:02:39] *** zrunn has quit IRC

[00:02:40] <Elvanor> but in that case I may as well give up and parse the parameters myself I think

[00:03:11] <Elvanor> yobo2: a local POST also seems a bit strange by the way :)

[00:05:53] <crackintosh> is this incorrect? static public void main(String[] argc)

[00:06:02] <crackintosh> should it be public static void main

[00:06:15] <cybereal> what did the compiler tel you?

[00:06:36] <crackintosh> Exception in thread "main" java.lang.NoSuchMethodError: main

[00:06:50] <crackintosh> i am trying to run this from the command line

[00:06:53] <crackintosh> it works fine in eclipse

[00:07:08] <cybereal> then you're probably formulating your classpath or command line wrong

[00:07:25] <cybereal> eclipse runs things with a regular vm, it's not magic or something

[00:07:25] <cheeser> ~~ crackintosh newbie ide

[00:07:25] <javabot> Newbies shouldn't start with IDEs.  It's important to learn the environment and fundamentals of a language before offloading those to an IDE.  Learn about packages and imports and classpaths.  Learn how to compile and use the JDK tools.  Get some basic grasp of the API layout.  Learn how to do things then switch to an IDE to do them faster.  See http://tinyurl.com/yvks48 and and http://tinyurl.com/2cpn6o for more info.

[00:11:08] <cheeser> Elvanor: it's apparently not clear enough for you so i'll spell it out:  if someone knew how to fix your hairbrained code, someone would've said by now.  so can you please spare us and try some other forum?

[00:11:08] <svm_invictvs> All the available attributes?

[00:11:16] *** yorky501 has left ##java

[00:11:20] <cheeser> attributes bing the JAXB elements?

[00:40:53] <cheeser> i'm checking what it is.

[00:41:04] <Shirik> ah

[00:41:05] <cheeser> so, yes, "normally" the compiler will catch it.

[00:42:04] <cheeser> or  you're using a jar at runtime that hasn't been rebuilt

[01:07:39] <supersako> hey guys quick question about args[]

[01:07:43] <KingBilly> 2 weeks ago i didnt know what to do with a .java file im amazed ive even gotten as far

[01:07:53] <supersako> if i run a file with java filename.java < input.txt

[01:08:18] <supersako> and say input.txt has one line that reads 438932573285729834783274

[01:08:25] <supersako> will args[0] be that number ^

[01:08:33] <reverend> those aren't args, that's stdin

[01:08:38] <cheeser> supersako: you don't run code like that so ...

[01:09:17] <supersako> ya

[01:09:19] <supersako> i forgot

[01:09:31] <supersako> i meant java -jar filename.jar < input.txt

[01:09:39] *** sphenxes has quit IRC

[01:09:48] <supersako> i guess the program still has to have a way to handle the stdin and it wont work with args[]?

[01:09:53] <ScottG489> Does the Array.length() method return the total size of an array or the size that has been filled?

[01:09:59] <reverend> input.txt isn't an arg

[01:10:06] <cheeser> ~~ ScottG489 tias

[01:10:06] <javabot> Try it and see. You learn much more by experimentation than by asking without having even tried.

[01:10:11] <reverend> the < operator pipes the contents to stdin

[01:10:17] <r0bby> ScottG489: it's a field not a method.

[01:10:25] <reverend> and effectively ends your command

[01:10:29] <tieTYT> does anyone here feel confident about their understanding of the SRP?

[01:10:35] <r0bby> for(int i=0;i<array.length;i++) { ... }

[01:15:08] <poseidon> I have a singly linked list which I have sorted in a certain order. What would be the best way for me to show it in a JList?

[01:15:12] <cheeser> why should i bother to type correctly if you're clearly not going to read it?

[01:15:24] <cheeser> poseidon: witha ListModel?

[01:15:44] <tieTYT> clearly based on what?

[01:15:55] <tieTYT> the factoid itself is about a priniciple I read about

[01:16:00] * cheeser sighs

[01:16:07] <cheeser> ok.  i'm done talking to you for a while.

[01:16:08] <poseidon> cheeser, Thats what I was thinking from my reading, but I'm not quite sure about how a ListModel works, where can I learn more about it?

[01:16:13] <cheeser> fuck!

[01:16:13] <cheeser> 8^)=

[01:16:17] <pgib> poseidon, considering it is a linked list, you are either going to have to iterate to the right position (this is a given for linked lists) or keep an index of sorts

[01:24:41] <warriorforgod> If I enter 0 to start it terminates correctly, however if I enter 0 after the first round of data is entered it just continues to loop.

[01:25:32] <cheeser> ~~ warriorforgod paraphrase

[01:25:32] <javabot> Don't paraphrase code or errors.  If you knew what was important to show us, you wouldn't need us to answer your question.  You should pastebin the *actual* code and the *actual* error.  Anything else is most likely going to be useless.

[05:51:51] *** musically_ut has joined ##java

[05:51:54] <AMcBain> you can either do "return;" or just set it up so that the method ends without calling the recursive case.

[05:51:57] <_some0ne> right, so i was thinking i'd make it int, but obviously you had somethign esle in mind

[05:52:24] *** supersako has joined ##java

[05:53:49] <AMcBain> your method is void. it *can't* return anything.

[05:54:03] <_some0ne> http://rafb.net/p/1fS8Ge46.html

[05:54:05] *** Wicked has quit IRC

[05:54:17] <_some0ne> now obviously maxStars has to get altered somehow

[05:54:27] <AMcBain> no ... you don't want to do System.exit(10

[05:54:29] *** Wicked has joined ##java

[05:54:31] <AMcBain> exit(1)

[05:54:43] <_some0ne> but it doesn't increase linearly..

[05:55:11] <_some0ne> pl

[05:55:12] <_some0ne> ok

[05:55:13] *** waz has joined ##java

[05:55:21] <AMcBain> System.exit doesn't just end your recursion, it ends your program too.

[05:55:30] <AMcBain> (you only want to end the recursion)

[05:55:51] <_some0ne> if ()!(indent == maxStars - 1))  , ast(indent + 1, (maxStars + 1) / 2);

[05:56:00] <_some0ne> that () is accidental

[05:56:32] <AMcBain> uh ... no. you don't really want to modify maxStars ...

[05:56:56] <AMcBain> and you can do if(indent < maxStars) instead of whatever you did there.

[05:57:04] <_some0ne> *facepalm* didn't mean to paste that either

[05:57:51] <AMcBain> seems like you did ...

[05:58:00] <_some0ne> in past trials

[05:58:17] <_some0ne> ok: if (indent < maxStars) THEN ast(indent + 1, maxStars);

[05:58:53] <_some0ne> whoops..

[05:59:02] *** rlubke has quit IRC

[05:59:40] <AMcBain> okay, that seems good (save for the large "then" :P)

[06:00:17] *** aleksei has quit IRC

[06:00:32] <_some0ne> still doesn't make sense to me that we increment indent by 1, since in the given example (where the initial parameters were 0 and 8), indentation doesn't increase linearly

[06:00:54] *** Honk has joined ##java

[06:02:05] *** spathi^ has quit IRC

[06:03:12] <AMcBain> yes, but dividing maxStars will only make it smaller and smaller, and it's obvious that in the middle you need to know what the original value of max stars is.

[06:03:18] *** nor3 has joined ##java

[06:03:31] <_some0ne> well neither way is correct

[06:10:26] *** jcp has joined ##java

[06:10:32] <_some0ne> well, if for every single recursion until the stopping case we print the number of spaces, then increment that number, then the number of spaces increases linearly, doens't it?

[06:22:17] <_some0ne> well, how is the way you setup indentation not linear?

[06:22:51] <AMcBain> but just because it seems to be linear, (I do x+1) doesn't mean the output has to be ...

[06:26:24] <AMcBain> _some0ne: probably a function based on the indentation.

[06:26:51] <AMcBain> but I'll let you work that out.

[06:27:01] * AMcBain returns to his work already in progress.

[06:28:07] <_some0ne> AMcBain, i appreciate your help thus far, but honestly, the problem is that i don't see a clear pattern in the example pattern i posted. i could handle the syntax if i understand how the fractal pattern changes

[06:28:25] *** porter1 has joined ##java

[09:49:49] <elmomalmo> RatPack: just type javac on the command line, it will tell you the usage

[09:50:10] *** dnmo has quit IRC

[09:50:36] <mitch0> I think he wants the reverse (.class -> .java). not entirely sure though ;)

[09:50:46] <elmomalmo> :-)

[09:50:49] <RatPack> No, the other way around, lol

[09:51:00] <ankylose> i can use it only with oracle database provider

[09:52:43] <RatPack> "'javac' is not recognized as an internal or external command, operable program or batch file" that's no good news o.O

[09:59:42] *** thpar has joined ##java

[10:00:03] <RatPack> Of course

[10:00:35] <deufrai> then you have a PATH issue

[10:00:46] <deufrai> I see you're under windows, right ?

[10:00:53] <RatPack> Correct

[10:01:07] <deufrai> just add the 'bin' directory of your installed JDK to you PATH

[10:01:48] <RatPack> I'd assume the javac command would go in the Command Prompt ("DOS"), right?

[12:59:03] <W_work> heh

[12:59:25] *** J0bk has joined ##java

[13:03:07] <jottinger> kjkoster5489: an implementation of ODBC in Java? Trying to connect to Derby with a windows app, I take it?

[13:03:48] *** L-----D has joined ##java

[13:03:49] <roots_> there several vendors that offer base odbc libs

[13:03:51] <kjkoster5489> jottinger: kind'a.

[13:04:04] <roots_> eg abstract odbc impl. frameworks that you can extend to a full blown odbc

[13:04:21] <roots_> but don't do it

[13:04:30] <kjkoster5489> I want an Erlang app to connect to my Java app so that both the erlang app end the Java app slare hibernate cache.

[13:04:33] *** blankthemuffin_ has quit IRC

[13:04:45] <kjkoster5489> roots_: any names or web links?

[13:04:47] <roots_> you most certainly have other options which cost you less

[13:04:50] <jottinger> errrrr... that won't actually help much

[13:05:06] <kjkoster5489> Googling for this justy gives me loads of references to the old brodge that I don't want. :)

[13:05:19] <roots_> datadirect is the big player

[13:05:33] <roots_> thats a company

[13:05:33] <W_work> kjkoster5489: what on earth did you google for? "JDBC-ODBC bridge"? Try the other way around

[13:05:33] <jottinger> sharing hibernate cache won't do much unless you can share the hibernate *session*, and since sessions should be short-lived...

[13:06:06] <kjkoster5489> Not even 2nd level cache?

[13:06:22] <jottinger> 2nd level cache isn't much of a win

[13:06:42] <kjkoster5489> *shrug*

[13:06:54] <kjkoster5489> Yeah, well, that is not for me to decide.

[13:07:32] <kjkoster5489> It does mean that the ACID layer is in Java, not in the database, so if the Erlang app and the Java app want to share database data, they need to both use the same 2nd level cache.

[13:07:37] *** Angel-SL has quit IRC

[13:08:04] <roots_> such designs are usually full of problems

[13:08:17] <roots_> unless done by real good programmers, but those don't do that in the first place

[13:08:52] <kjkoster5489> Yeah, well.

[13:09:04] <kjkoster5489> Nothing I can do about it at this stage.

[13:09:17] <jottinger> kjkoster5489: what you should do is tell them to use java as a service layer

[13:09:38] <kjkoster5489> They don't want to change the Erlang app.

[13:09:40] <jottinger> at least run it up the flagpole, because otherwise your implementation, if it works at all, will fail

[13:09:44] <kjkoster5489> And it uses ODBC.

[13:10:05] <jottinger> then let it use ODBC. Why do they want to share the cache?

[13:10:05] <roots_> i dont see why you need an odbc impl ?

[13:10:07] <kjkoster5489> The flagpole is already full of flags. Memcached, jgroups.

[13:10:20] <jottinger> roots_: I don't either

[13:10:20] <roots_> forget about the hibernate cache

[13:10:25] <jottinger> I'm starting to feel sorry for him

[13:10:29] <roots_> forget about hibernate if you want to

[13:10:32] <kjkoster5489> Me too.

[13:10:47] <roots_> i mean a ORM cache is questionable in the first place

[13:10:55] <roots_> it certainly limits you, though it may add performance

[13:11:11] <roots_> unscaling, unreliable, non-redundant, non-failsafe performance

[13:11:12] <jottinger> roots_: the amount of performance they add usually isn't that great :(

[13:11:14] <kjkoster5489> I believe that ACID should be done in the database.

[13:11:18] <kjkoster5489> Not in Java.

[13:11:19] <roots_> and even that it doesnt add

[13:11:42] <roots_> i believe that acid should be done by every male at least 10 times

[13:11:52] <kjkoster5489> Otherwise you can't even make sane backups with the normal system tools.

[13:12:07] <kjkoster5489> But hey, we're not all in the position to decide.

[13:12:07] <roots_> just for enjoyment

[13:12:14] *** The_Birdman has quit IRC

[13:12:23] <roots_> the cache is not write-through ?

[13:12:29] <roots_> congrats

[13:12:40] *** musically_ut has quit IRC

[13:13:35] <kjkoster5489> So you are saying there is no open source (partial) ODBC marshalling library, other than the stuff in Sun's ODBC/JDBC bridge?

[13:13:55] <roots_> kjkoster5489: nothing you can use, there is a few base lib that are free

[13:14:02] <roots_> but nothing you can use in any serious app

[13:14:07] <roots_> i mean odbc is dead

[13:14:20] <kjkoster5489> Ok, well, thanks for the help.

[13:14:57] <roots_> check out iODBC

[13:42:55] <b0red> hi.  I'm passing Integer to a method and incrementing it in that method.. but then after that method the integer seems to be incremented.. why?

[13:43:18] <isr`> b0red: are you using the final modifier?

[13:43:31] <b0red> no

[13:43:39] *** schasi has quit IRC

[13:43:44] <b0red> and Integer is being increment in that method scope

[13:44:01] <b0red> Integer x; foo(x) { x++; }; print x;

[13:44:10] <isr`> yeah, it doesnt matter, you are passing it the reference of the Integer

[13:44:15] <b0red> yes!

[13:44:55] <isr`> yeah

[13:44:57] <mitch0> erm

[13:45:01] <mitch0> Integer is immutable

[13:45:37] <paulweb515_> ~~ b0red pbv

[13:45:55] <b0red> ?

[13:46:18] <paulweb515_> Java is Pass By Value (javabot has more info, but apparently not at the moment)

[13:46:40] <b0red> no, it's pass by reference to Objects

[13:46:48] <ilyak> ~pbv

[13:46:54] <ilyak> indeed he's dead

[13:46:59] <b0red> for objects*

[13:47:01] <paulweb515_> b0red: no, Java is Pass By Value (it's actually passing the reference by value)

[13:47:15] <paulweb515_> b0red: the "law" (JLS) is clear on this one

[13:47:20] <b0red> paulweb515_: yes.. passing the reference by value

[13:47:27] *** Aseq has joined ##java

[13:47:31] <ilyak> passing reference by value is like kicking butt without butt

[13:47:32] <roots_> which is pass by ref to some

[13:47:33] <ilyak> makes no sense

[13:47:43] <paulweb515_> b0red: but your problem is what mitch0 mentioned, Integer is immutable

[13:47:43] <b0red> paulweb515_: so if i change Integer inside that method... the object's state should change as welll

[13:47:48] * jottinger sighs

[13:47:49] <b0red> I see

[13:47:51] <roots_> but what actually happens is clear to everyone :)

[13:47:51] <jottinger> b0red: no

[13:47:58] <jottinger> only if you change to a new reference

[13:47:58] *** DragonLord- has joined ##java

[13:47:59] <b0red> jottinger: ony in case of Integer

[13:48:02] <jottinger> nteger is immutable anyway

[13:48:06] <ilyak> you're either passing things by reference or by value, or else you're trying some bizzare word play

[13:48:13] <jottinger> no, in the case of ANY object that's immutable

[13:48:14] <ilyak> What you surely shouldn't do, stay clear

[13:48:16] <roots_> jottinger: only java.lang.Integer

[13:48:20] <jottinger> ilyak: you're passing a copy of the reference

[13:48:21] <roots_> not com.someone.Integer

[13:48:22] <b0red> jottinger: yeah

[13:48:31] *** Ven]n has joined ##java

[13:48:39] <b0red> jottinger: for immutable objects

[13:48:52] <ilyak> jottinger: you can't have a reference to reference

[13:48:52] <jottinger> b0red: no

[13:48:53] <b0red> jottinger: how can I deal with that?

[13:49:00] <ilyak> it would be no longer a reference

[13:49:00] <jottinger> you cannot change the *reference* for the caller

[13:49:05] <jottinger> you can change values pointed to by the reference

[13:49:09] <ilyak> hence: how else can you pass a reference?

[13:49:12] <Ven]n> whats the best way to make JSlider resize when adjusting the window? putting it in a JFrame or something?

[13:49:25] <jottinger> I can't believe people who know Java are still discussing this

[13:49:25] <isr`> ilyak: you can pass a reference by value

[13:49:52] <ilyak> isr`: but you can't pass a reference by reference!

[13:49:59] <isr`> ilyak: exactly

[13:50:01] <ilyak> so 'by value' is redundant

[13:50:06] <ilyak> you just pass a reference

[13:50:11] <Ven]n> (if for instance I maximize the window.. I want the JSlider to increase in size. :P . like a pack();

[13:50:16] <isr`> you can pass a reference by reference in other languages

[13:50:20] <isr`> ie: a pointer.

[13:50:26] *** Bleadof has joined ##java

[13:50:34] <ilyak> pointer is not a reference really, different semantics

[13:50:40] <jottinger> it's not redundant

[13:50:47] <ilyak> you can pass a pointer by value or by reference

[13:50:54] <b0red> jottinger: I want a mutable Integer then..

[13:50:57] <ilyak> but you can only pass a reference in one way

[13:51:06] <ilyak> pass a reference, period

[13:51:11] <jottinger> b0red: java.lang.Integer is immutable.

[13:51:20] <b0red> jottinger: any alternative classes?

[13:51:24] <jottinger> Pass a container that points to an integer, and change what the container points to.

[13:51:53] *** paulweb515_ has quit IRC

[13:51:53] <ilyak> b0red: pass an Integer[1]

[13:52:23] <roots_> you could pass an Integer[][] and the length of the array nested in slot[0] indicates the length

[13:52:23] <b0red> array of one Integer?

[13:52:25] *** shadewind has joined ##java

[13:52:27] <ilyak> b0red: yeah

[13:52:30] <jottinger> i.e., class IntegerHolder { public Integer foo; } ... myMethod(IntegerHolder ih) { ih.foo=new Integer(ih.foo.intValue()+1); }

[13:52:31] <roots_> array lengths make up nice integers

[13:52:38] <jottinger> or an array of one, sure

[13:52:44] <roots_> not really space compact but on this level it shouldnt matter

[13:52:54] <jottinger> why are you doing this anyway?

[13:53:05] <ilyak> roots_: arrays are inresizeable, too

[13:53:08] <ilyak> so you can't really

[13:53:14] <kjkoster5489> Bleh. And people moan about me wanting to expost ODBC from Java as bad practice.

[13:53:16] <ilyak> s/in/ir

[13:53:17] <roots_> sure you can

[13:53:20] <roots_> ilyak: [][]

[13:53:22] <roots_> not just []

[13:56:58] <shadewind> I have some clues

[13:57:06] <isr`> mm i think im getting a clue

[13:57:07] <fragalot> I have cluedo, does htat count?

[13:57:08] <shadewind> but clues I have :)

[13:57:13] <isr`> oo my clue is pointing over there

[13:57:14] <jottinger> I think it was the butler, in the billiards room, with a wrench

[13:57:18] <mitch0> but that x++ is actuall x = new Integer(x.intValue()++). I think it's horrible

[13:57:46] <shadewind> mitch0: it's what you should expect if you're using Integer

[13:58:07] <isr`> yeah, Integer is just a wrapper class for int isnt it?

[13:58:35] <isr`> seems like overkill for an int operation.

[13:58:40] <isr`> like x++;

[13:58:47] <shadewind> indeed

[13:58:52] <mitch0> oh well, I just steer away from autoboxing whenever possible

[13:59:08] <shadewind> eveything sucks when you don't undestand how it works

[13:59:15] <isr`> i guess no one got my south park joke... the hardly boys.

[13:59:39] <shadewind> it's SBS as we say in swedish

[13:59:42] <isr`> shadewind: i understand what Integer is for, i just dont understand why you'd use it when clearly an int would suffice

[14:00:07] <jottinger> isr`: The wrapper classes descend from Object, which the primitives do not

[14:00:12] <shadewind> isr`: right

[14:00:28] *** eidolon has quit IRC

[14:00:34] <shadewind> I think he gets that

[14:00:39] <isr`> of course.

[14:00:46] <shadewind> there is no reason to use Integer when an int is enought

[14:00:48] <shadewind> *enough

[14:01:01] <shadewind> which is almost always

[14:01:03] <isr`> exactly, that's my point

[14:01:20] <shadewind> except for collecitons 'n' stuff

[14:01:27] <isr`> yea

[14:01:38] <isr`> then i could see why you would have to use Integer instead

[14:02:04] <shadewind> most of the time, I just go ahead and use autoboxing

[14:02:13] <shadewind> in that case that is

[14:02:26] <isr`> autoboxing?

[14:02:44] <isr`> two cars slugging it out?

[14:02:46] <shadewind> I only store the ints (or doubles or whatever) as Integer but as soon as I get them out of there I unbox them

[14:02:52] <shadewind> isr`: no

[14:03:00] <isr`> :-P

[14:03:01] <shadewind> ~~ isr` autoboxing

[14:21:04] <jottinger> it's not the same as your code

[14:21:07] <Alvo> @jottinger: too bad, thanks

[14:21:31] <jottinger> but if you want ints like that, there are ways to do it

[14:21:42] <jottinger> but it doesn't seem like a good case for an enum if that's what you want

[14:29:11] <jottinger> aleksei: tell you what, let me google that for you

[14:29:19] <jottinger> rejeep: entirely installation-dependent

[14:29:26] <isr`> there is a bug that prevents JComboBox from being rendered correctly

[14:29:28] <jottinger> I use com.foo.services

[14:29:30] <AqD> aleksei: pass -Dswing.aatext=true

[14:29:39] <aleksei> jottinger: i did that

[14:29:40] <isr`> or whatever the swing combobox class is

[14:29:42] <AqD> aleksei: unless the app has custom look&feel, the option should work

[14:30:07] <jottinger> aleksei: so you found the answer?

[14:30:09] <aleksei> AqD: but how do you do that systemwide

[14:30:12] <Alvo> @jottinger: actually i want to map enums to integer values for hibenate, i guess theree is another solution for that

[14:30:24] <AqD> aleksei: modify java class :D

[14:30:28] <aleksei> jottinger: yes! I'm asking just for fun

[14:30:30] <AqD> i had patch for that, v1.5 i remember

[14:30:40] <AqD> aleksei: no other way for system-wide ;)

[14:36:11] <deufrai> hi there. A question about typed collections. I'm finally migration to 1.5 (yeah, I know). I'm using the commons-configuration library and particularly the Configuration.getList(String key) method. This method returns a java.util.List, raw. As I know that said list contains String instances, I'd like to store those in a List<String> inside a wrapper object.

[14:36:12] *** aleksei has joined ##java

[14:36:33] <deufrai> question is : how do I avoid the warnings about unchecked conversion ?

[14:40:51] <durre> also, if it's any clue. the new environment complained about my <logic:iterate id="broker" indexId="i" name="brokers"> ... where "i" in the new environment seems to be of the type Integer and not int

[14:41:00] <jottinger> rejeep: sure. your IDE may complain though.

[14:41:42] <rejeep> jottinger: Ok. Do you think that package after models, controllers, views, etc... is good?

[14:41:49] <deufrai> squiddle: I'm used to consider warnins as errors (at least mentally)

[14:41:50] <rejeep> So "package app.models"

[14:41:53] <elmomalmo> conan: you could use mocks

[14:42:27] <conan> i looked at jmock it doesn't seem to have anything for that. where I have a URL and it's opeStream() method will work.

[14:42:32] <jottinger> rejeep: sure

[14:42:37] <jottinger> whatever works for you, man

[14:42:44] <rejeep> jottinger: =)

[14:43:00] <rejeep> jottinger: So packaging is basically a way of finding stuff?

[14:43:02] <deufrai> squiddle: can you think of another reasonnable way around ?

[14:43:10] <elmomalmo> conan: I'd isolate the logic of detecting changes from the connecting to the URLs. Then you can mock the classes doing the HTTP conecting etc

[14:43:12] <jottinger> rejeep: do you not understand java packaging?

[15:49:51] <jottinger> main() and web.xml won't make any difference. If you're using JNDI resources, you'll have to run Tomcat and connect to its JNDI server, and java:comp/env won't work in any event unless you do some parsing on the part of your application.

[16:27:03] <kercyr> marvi, in Linux, ping requires more privilege than you'd usually want in the java program.

[16:27:15] <jeremy_c> um, nm. that's silly. I didn't see it in autocomplete, but it's pretty simple, sorry for the silly question

[16:27:21] <marvi> kercyr: this is on Windows.

[16:27:49] *** macdaddy has joined ##java

[16:28:19] <kercyr> marvi, well, I don't know much about Windows, but probably the same thing applies.  Java just doesn't have privilege to that part of the OS.

[16:28:50] <nater> jottinger: applets have their uses... admittedly its a rather narrow niche but it exists

[19:00:55] <dude7064> sproingi> Thanks

[19:00:58] <Stephmw> so custom layouts, still a better solution than absolutes in the container

[19:01:02] <sproingie> you look for small fonts with those

[19:01:14] <Stephmw> sproingie: I've worked in embedded java too with fixed layouts

[19:01:53] <sproingie> anyway, it's easy enough to absolutely position, just don't use a layout manager at all

[19:02:11] <Orakio> Use spring layout

[19:02:28] <q2dm1> sprongie: yep, but then the subcomponents arent clipped

[19:02:30] <Orakio> I've always sound that directly setting the size of stuff messes up

[19:02:31] <Stephmw> sproingie: sure, but he was asking how to avoid them overlapping

[19:02:44] <Stephmw> layout managers make managing this much easier

[19:02:51] <Stephmw> regardless if it's a custom one

[19:03:03] <sproingie> stick 'em in a panel that clips 'em?  eh.  grid layout manager, fine grid.

[19:03:22] <Orakio> Oh goodness not gridbaglayout

[19:03:28] <sproingie> god no not gridBAG

[19:03:32] <sproingie> just grid

[19:03:46] <Orakio> I still stand on spring layout :)

[19:03:51] * Stephmw hugs gridbaglayout... in small doses

[19:03:55] <Orakio> us that or border/card layout, ie very simple ones

[19:03:58] <sproingie> springies are my favorite for obvious reasons

[19:04:09] <q2dm1> sprongie: and cpu performance doesnt depend on the gird size cause id need a 1x1 grid :)

[19:05:28] <Stephmw> never have to maintain them?

[19:05:50] <Stephmw> my experience of clicky gui designers makes for non-trivial UIs that aren't code-maintainable

[19:05:53] <sproingie> doing it "right" just doesn't feel like a great accomplishment.  it's just a front end.

[19:06:00] <sproingie> the code they generate is awful, but i don't touch it

[19:12:29] <lami1984> hello

[19:12:33] <EdwardIII> speaking of .net->java development - the developer (c#.net) at work does a lot of OO stuff so i keep abreast of what he's upto. when he creates a container for a load of objects (e.g. Feed->entries() returns a entryCollection) instead of it returning an arraylist or whatever it returns a specific EntryCollection type - is this good? in my little feedreader project i just return a Collection filled with entries which i for loop through, get the Ob

[19:13:17] *** eduardopl has quit IRC

[19:13:51] <sproingie> i think sticking to collections is a good idea, or at least providing a collections interface on demand

[19:14:36] <^Migs^> I have a project, where we have a group of conference attendees who are signing up for classes. They list which classes they want, then our automated system automatically best-fits them into the class slots.  Is there an algorithm that does something similar, that anyone knows about?

[19:15:06] <EdwardIII> i guess unless you needed a specific Collection method which wasn't available in the default Collection object then it would just be bloat, right?

[19:15:11] <FauxFaux> ^Migs^: Scheduling is Hard, it's a classic AI problem, hundreds of implementations.

[19:15:23] <^Migs^> hmmm

[19:15:30] *** _acid__ has joined ##java

[19:15:30] <^Migs^> that's not reassuring

[19:15:32] <EdwardIII> or rather i should say a method that wasn't available in the interface, or didn't do what you wanted

[19:15:58] <sproingie> perfect scheduling is np-complete (it's bin-packing).  thing is, there's human factors involved too

[19:16:04] *** skoskav has joined ##java

[19:17:24] <sproingie> EdwardIII: as long as you have some way to get at a collection, it's more a matter of taste.  you're implementing collection directly, he's providing an implementation.

[19:18:14] *** monkeycid has joined ##java

[19:18:56] <EdwardIII> well in my example i'd just be Extending the Collection class and insofar as i can see using a Collection with a custom name which just seems like pointless bloat. i guess the only benefit in my case would be a) code sexyness b) not needing to cast Object to my custom Feed object

[19:18:57] *** skoskav has quit IRC

[19:19:48] <EdwardIII> sproingie: generic like <Roflcopters>, right?

[19:19:59] <q2dm1> hmm i think the clipping happens in the RepaintManager, not in the Layout

[19:20:03] <sproingie> Collection<RoflCoptors>, sure

[19:20:14] <sproingie> it's probably best to return a collection, not inherit it directly

[19:20:29] <sproingie> unless you know your class serves no other purpose than as a collection

[19:20:40] <EdwardIII> hmm

[19:20:48] <EdwardIII> the guy at work usually creates specific container classes

[19:21:01] <sproingie> long as they implement the interface, that's fine

[19:21:09] *** cvasilak has joined ##java

[19:21:14] <FauxFaux> Like all of the java.util.* stuff, all of the "interfaces" aren't interfaces at all, they're huge sprawling octupusses.

[19:21:28] <sproingie> collections isn't that bad

[19:21:44] <sproingie> of course most of the time you really just need an iterator

[19:21:44] <lami1984> I'm preparing for the scjp 6.0 exam and while doing various tests I came across a really interesting question.The question is: how many objects are aligible for GC in //here (the answer is 2). I understand it but I thought that integer literals in range of byte are pooled and not dealocated... What about string literals?  http://eugeneciurana.com/pastebin/pastebin.php?show=40539

[19:22:07] <EdwardIII> so the hierachy looks like (in the feedreader example) Feed->getEntryCollection() returns a -> EntryCollection instance which contains -> Entry instances

[19:22:08] <FauxFaux> 14 methods "isn't that bad"?

[19:22:10] <EdwardIII> ho hum

[19:22:22] <sproingie> i didn't say it was great.  it could be worse.

[19:22:26] <EdwardIII> FauxFaux: is 14 methods a lot? there must be some way more beastly interfaces than that?

[19:22:49] *** yrlnry has joined ##java

[19:24:42] <sproingie> what i don't like are the "optional" parts

[19:24:56] <FauxFaux> lami1984: I /expect/ (don't guarantee) that any pooling of objects is an artifact of Sun's implementation and not in the spec.  And string literals aren't subject to garbage collection, as such.

[19:25:11] <sproingie> it lets things renege on the interface contract

[19:25:16] <sproingie> you may as well be duck typing

[19:25:22] <EdwardIII> quack

[19:25:26] <FauxFaux> One interface per method time.

[19:25:39] <FauxFaux> And v.v.

[19:25:43] <lami1984> FauxFaux: you mean that when we overide s with "String s = "aaa"" the apropriate answet will be 1 in this case?

[19:26:07] *** repnop has joined ##java

[19:26:35] *** Seldon75 has joined ##java

[19:27:14] <FauxFaux> Uncommenting s has no affect on garbage collection, afaik.  Except that the literal may be deallocated when all instances of Test itself are gone, but, again, the spec probably just says that string literals always have the same reference.  Actually, that's gauranteed across classloading, isn't it?

[19:27:26] <FauxFaux> I hate reading specs!  Nobody even cares!

[19:27:32] <sproingie> is string interning ever guaranteed?

[19:27:43] <FauxFaux> Literals are always interned.

[19:27:54] <sproingie> guaranteed by the JLS?

[19:28:04] <FauxFaux> Just checking.

[19:28:27] *** squi has quit IRC

[19:28:30] <FauxFaux> 3.10.5 [...] String literals-or, more generally, strings that are the values of constant expressions (§15.28)-are "interned" so as to share unique instances, using the method String.intern.

[19:35:16] <lami1984> <popcornPanic> you dont add it, you add buttons

[19:35:27] <cheeser> almost 10 years

[19:35:29] <cheeser> 8^)=

[19:35:34] <FauxFaux> sproingie: Is that the same as saying that a string literal /always/ has the same reference during the lifetime of a jvm?

[19:35:35] <yrlnry> I was using the standard extended by java.io.StreamTokenizer class, which worked fine when I was deadling with ISO-8859-1 files.  But now I need to handle UTF-8 encoded Unicode files, and I have just discovered that StreamTokenizer will only read its input byte-by-byte.  I could reimplement a Unicode-aware version of StreamTokenizer, but I hoped you folks might have a suggestion for something that I could get working quicker.

[19:35:38] <yrlnry> Any thoughts?

[19:35:41] <EdwardIII> cheeser: really? were you a vim boy?

[19:35:45] <cheeser> yep

[19:35:53] <lami1984> ;)

[19:36:15] <EdwardIII> i'm using vim at the moment... it does contain a lot of clever formatting stuff, plus i'm starting to get quite quick at flicking around text using it's features too

[19:37:07] <EdwardIII> i do a fair amount of sysadminnery at work

[19:37:51] <sproingie> FauxFaux: it may move the reference around if it wants, but the same literal, computed from constants or not, will always point to the same instance

[19:38:34] <sproingie> doesn't even mention different classloaders

[19:40:12] <Seldon75> yrlnry: why are you using StreamTokenizer?  could you use a Scanner instead?

[19:40:24] *** q2dm1 has left ##java

[19:40:40] <yrlnry> Seldon75: perhaps.   I'll look at Scanner.  Thanks.

[19:42:12] <yrlnry> Me neither, but it's worth a look.

[19:42:32] <yrlnry> At first glance it seems that I can reimplement StreamTokenizer in terms of Scanner.

[20:21:46] <javabot> ernimril, tijmp is a small, fast and easy to use memory profiler for java/6 and later. See http://www.khelekore.org/jmp/tijmp/

[20:31:54] <ernimril> Seldon75: that would make it soo much better

[20:32:10] <vsayikiran> ernimril: ok more question, if i have a number of classes grouped under various jar files, and one of the jar files has a main method then will be able to test my apps for memory leak

[20:32:16] <Seldon75> that's right - I can't comprehend plain black on white text

[20:32:31] <Seldon75> so, just put that in your bug tracker as a Critical

[20:32:52] <ernimril> vsayikiran: a profiler sees whatever classes the jvm has loaded

[20:33:14] <ernimril> vsayikiran: where the classes come from does not matter

[20:33:42] <ernimril> vsayikiran: for jmp there is a users guide that you could try reading

[20:40:41] <ernimril> vsayikiran: you can easily find how many instances there are of each class in your jvm, you can also show owners to figure out why the objects are still kept in memory (short answer: yes)

[21:40:54] <__phil__> apologies - I was concerned my question had been lost in the mix of conversations.  ernimril / shadewind - we need to know because before we do any image rendering, we want the image to be CMYK.  RGB therefore needs conversion.

[21:41:35] *** Gracenotes has quit IRC

[21:42:20] <elad`> ldamwork: Another question - how do I make the red one (sw) five times as thick (both horizontally and vertically) as the blue ones, and the green one in proportion?

[21:42:38] *** bindaas has quit IRC

[21:42:38] <ldamwork> elad`, adjust weight

[21:42:39] <elad`> (In proportion - forming the rest of the square.)

[21:42:44] <elad`> Yes, but in what way?

[21:42:57] <elad`> I played with it and got random looking results.

[21:43:11] <ldamwork> elad`, note: weight is how the extra space is going to be distributed, let me give an example:

[21:43:20] *** Goundy has quit IRC

[21:43:22] <dude7064> Do I have to write the pattern in a specific way to allow for the detection of multiple spaces ??

[21:43:27] <vinse> dude7064: works in js: /^[\d\. ]{8}/.test("0 0.0.34"); true ... you're doing something wrong.

[21:43:30] <vinse> dude7064: no

[21:43:47] <dude7064> !!

[21:43:57] <vinse> oops i pasted that wrong

[21:44:11] <ldamwork> elad`, have a content with width=100px, and two panels A.width=20px, B.width=30px; this means there are 50 extra pixels left.

[21:46:20] *** EdSquareCat has left ##java

[21:46:47] <vinse> dude7064: /^[\d\. ]{8}$/.test("0 0.034"); true ...  /^[\d\. ]{8}$/.test("0  0.034.3324324"); false

[21:47:17] <vinse> use the dollar sign to make sure trailing characters are handled, test with simpler regex to make sure you're using special characters correctly, etc.

[21:47:18] <ldamwork> elad`, if weight for A and B is 0, then the extra space is not used and the two componets are placed in the center, with 25px to the left and to the right. If there is weights assigned, then the remaining 50 pixels are distributed according to those weights. e.g. if weight =0/1, then the distribution is 0px/50px, so A.width=20+0 and B.width=30+50. If weight is 2/3, then the distribution=20px+30px. Weight1/1 gives 25px/25px etc. Weight is an arbitr

[21:49:45] *** eisenach has quit IRC

[21:49:45] <ldamwork> elad`, so the problem is that the size of you origanal components influences the real size; this you can avoid if you set the padding to a large negative value like -9999. In this case then the wdith of the cell is max(componentwidth+pad,0)+W which will give (20-9999,0)+W=0+W -> only weight will be used to set size

[22:02:45] <dmlloyd> possibly if you just renamed a .java to .class and expect it to work, for example

[22:03:15] <dude7064> Sou|cutter> shouldn't the pattern be sorrounded with something

[22:03:16] <dude7064> ?

[22:03:24] *** bindaas has joined ##java

[22:03:35] <dude7064> just to say that it can be found within text

[22:03:47] <dude7064> Sou|cutter> can you please give an example ?

[22:03:54] <isr`> so if i have an ArrayList<? extends Object>, basically I can use that array list for things that extend subclasses of Object also right

[22:04:20] <dmlloyd> no

[22:04:23] <EdwardIII> hrm dmlloyd good call - the class files are corrupt... i created them with Ant and i must have specified something wrong somewhere as when i try and run them outside the jar i get the same message

[22:04:44] <isr`> dmlloyd: was that for me?

[22:04:50] <dmlloyd> isr`: yes

[22:05:13] <dmlloyd> isr`: "ArrayList<? extends Object>" == "ArrayList<?>" == an array list for some type we don't know

[22:05:31] <isr`> dmlloyd: well this is what i am trying to do

[22:05:38] <dmlloyd> isr`: the only thing you can say for sure about such an arraylist is that .get() will return something that extends Object

[22:05:55] <isr`> I want to use a hashmap to map Strings to things that extend AbstractButton, mainly JMenuItem's and JCheckBoxMenuItems

[22:06:37] <EdwardIII> odd, rebuilt my app and now it's working. must've accidently trashed a .class file when messing around with tar earlier! thanks dmlloyd

[22:06:41] <isr`> because I dont want to keep references of a bunch of JMenuItem's arond

[22:06:49] <dmlloyd> isr`: ok, why not just use a Map<String, AbstractButton>

[22:07:00] <dmlloyd> EdwardIII: np

[22:07:29] <EdwardIII> sexcellent, got my first working jar now

[22:07:32] <isr`> dmlloyd: because map is an interface.

[22:07:39] <isr`> Map* rather

[22:07:50] <elad`> dmlloyd: Success. Thanks for your help. (The fight is not over, though.)

[22:07:54] <dmlloyd> isr`: so?  Map<Foo, Bar> = new HashMap<Foo, Bar>()

[22:07:55] <isr`> so you're saying i dont need to ? extends bit

[22:08:08] <dmlloyd> isr`: rather:  Map<Foo, Bar> xxx= new HashMap<Foo, Bar>()

[23:23:55] <Meshezabeel> cheeser: that is the whole purpose of what a static variable is. Is it not? To create a single reference in the computers memory so that all objects may use the same 'settings'.

[23:24:06] *** ttmrichter has joined ##java

[23:24:51] <cheeser> Meshezabeel: it clearly doesn't fit your needs, Meshezabeel, because you have the problem you do.  so stop doing that.  find a better way to share that data.  like, i dunno, a public non-static field.

[23:25:17] <tilerendering> cheeser that was not the answer to my question ;) but thanks

[23:25:46] <cheeser> tilerendering: no?  works in an EE container to a point.

[23:26:01] <cheeser> but, tbh, i've not used so i don't know how far down that road it gets you.

[23:26:03] <tilerendering> yes, but not for restful webservices with json

[23:26:19] <cheeser> ah

[23:26:27] <marvi> tilerendering: https://jersey.dev.java.net/

[23:26:28] <tilerendering> i know also the tags for restful/json

[23:27:30] <Meshezabeel> cheeser: the static variable is working perfectly throughout the program. However, when the user wants to start over from the main menu, I want the static variables to once again have their default values.

[23:28:07] *** ankylose has quit IRC

[23:28:08] <cheeser> then use a new classloader to relaunch the app.

[23:28:17] *** n3llyb0y has left ##java

[23:28:26] <cheeser> or bounce your JVM

[23:28:54] <Meshezabeel> okay, thanks cheeser

[23:29:09] <cheeser> but with statics, you're going to have this problem.

[23:29:20] <cheeser> which is why using them is dumb.

[23:29:34] *** ravv has quit IRC

[23:29:39] <Meshezabeel> then in what situation is it good to use a static?

[23:29:48] *** ravv has joined ##java

[23:29:51] <cheeser> for sharing values vs data

[23:30:17] <cheeser> e.g., "constants" etc.

[23:34:21] <Andrew`_> I'm developing a swing application, i want to have it so boxes can be move around / closed and stuff, like a sort of modular design

[23:34:28] <Andrew`_> is there any functionality provided for this anywhere?

[23:34:51] *** Zhig has quit IRC

[23:35:05] <cheeser> Meshezabeel: sure  8^)=

[23:35:48] <cybereal> Andrew`_: I don't think there is any standard api stuff for docking, but netbeans does it and it's built on swing... maybe that cna be of help

[23:36:07] <cheeser> ~~ Andrew`_ javadoc JInternalFrame

[23:36:07] <javabot> I don't know of any documentation for JInternalFrame

[23:36:52] <Andrew`_> ok cool cheers

[23:37:33] <Andrew`_> I really don't want to design it with netbeans

[23:37:39] <cybereal> cheeser: were thinking of MDI?

[23:37:40] <Andrew`_> i'm developing it in netbeans

[23:37:45] <Andrew`_> but i'm not using the GUI creator

[23:37:48] <Andrew`_> using MigLayout

[23:37:53] *** LostMonarch has quit IRC

[23:38:10] <cheeser> cybereal: yeah.  something like that.

[23:38:34] <cybereal> my very first swing app was MDI

[23:39:11] <cybereal> and also webstart :) back in ... 1.3

[23:39:24] <marvi> Andrew`_: Netbeans Platform is not about the GUI editor. It is a framework for modularity and window management. You can use whatever layout you want.

[23:39:29] <cheeser> hrm.  another bug in the javadoc importer

[23:39:30] <cheeser> 8^)=

[23:44:43] *** bas-i has joined ##java

[23:45:23] <pantcho> writeCHars() works ok, but IN.readLine() gives us a double string with for example if i got "Hello" i get "H E L L O" with some kind of spaces i think its a null char, why is that? is there a way to send strings in a normal reguler behavior?? thanks

[23:45:36] <lowki> i have a two dimensional array String[][] how do I get the first array? is there a method or do I have to write my own?

[23:45:44] <cybereal> ~is.gd is a URL shortening service in use for javadoc in javabot, if you don't trust those shortened url's, simply append a hyphen to the end of it and you will be taken to a page that exposes the entire URL.  See http://is.gd/ for more info.

[23:45:45] <javabot> Okay, cybereal.

[23:45:46] <cheeser> pantcho: it's an encoding issues

[23:49:47] <cheeser> depends on how you're reading it but typically ypu specify the encoding to the Reader

[23:50:17] <mySQLnoob> Hi, in jsp how do i find out the size of an array? i have: "<c:when test="${applicationScope.orders.size eq 0}">" where orders is an array, but this doesn't work

[23:50:51] *** illbeatu has joined ##java

[23:50:55] <cybereal> mySQLnoob: you're using JSTL, there's a function in there for it

[23:50:55] *** bas-i has quit IRC

[23:51:04] <cybereal> in the fn namespace by convention

[23:51:38] <mySQLnoob> cybereal: so i have to use another library for it?

[23:51:48] <cybereal> no, you're already using jstl

[23:52:01] <cybereal> if you are using the current version along with the "core" tags it has a functions set of... functions

[23:52:04] *** sebr has joined ##java

[23:52:08] <cybereal> usually assigned to the fn namespace

[23:52:19] <cybereal> do you even know what you're doing there with that <c:when...> tag? that's not standard jsp

[23:52:30] <cybereal> it's a taglib in the jstl library

[23:52:35] <mySQLnoob> so i have to add another tag <c:...> to find out the size and store it in a variable for comparison?

[23:52:41] <cybereal> no

[23:52:44] *** gregor_k has quit IRC

[23:52:47] <cybereal> it's a function so you can call it in your EL

[23:52:59] <cybereal> but you'll have to declare the use of the fn taglib

[23:53:04] <cybereal> just like you did for c

[23:53:15] <cybereal> ~~ mySQLnoob jstl

[23:53:16] <javabot> mySQLnoob, jstl is JavaServer Pages Standard Tag Library, http://java.sun.com/products/jsp/jstl/

[23:53:21] <mySQLnoob> that's what i meant by adding another tag

[23:53:25] <pantcho> cheeser: i am sending a string, the convertion is per each char of the input buffer, i read a whole string

[23:53:30] <cybereal> mySQLnoob: that's not what you said

[23:53:31] <pantcho> this means i need to change the sending method

[23:53:41] <cybereal> mySQLnoob: you don't have to set any variables for comparison

[23:53:50] <cybereal> mySQLnoob: your existing code will be slightly changed is all

[23:54:02] <pantcho> and its more work, their ust be a way to to convert a unicode string to a reguler char string with somekind of command

[23:54:10] <cheeser> pantcho: are you reading byte by byte?

[23:54:14] <cybereal> something like <c:when test="${fn:length(myarray) > 0}"

[23:54:18] <cheeser> ~~ pantcho show us

[23:54:18] <javabot> Paste the code (and any errors) in the pastebin where we can see it.  See ~pastebin for options.  Also see ~testcase for good examples as to how to help us help you quickly diagnose and solve problems.

[23:54:54] <mySQLnoob> cybereal: where myarray will be: ${applicationScope.orders.size}?

[23:55:07] <mySQLnoob> no no sorry

[23:55:28] <mySQLnoob> thank you

[23:55:33] <cybereal> yeah it's pretty simple, it's just that functions in a taglib are usable in an EL expression, just hav eto prepend their namespace name to the function name

[23:55:43] <cybereal> so yeah... declare the fn namespace properly and you'll be good to go :)

[23:58:02] <javabot> google has a karma level of 105, cybereal

[23:59:15] <mySQLnoob> cybereal: just out of curiosity, i already have "http://java.sun.com/jsp/jstl/core", if i were to declare "http://java.sun.com/jsp/jstl" wouldn't that take care of both libs?
