[00:04:43] <_W_> and I still wonder how ideals can be missplaced
[00:05:13] <cybereal> indeed, it's entirely plausible to have loads of technology without using someone else's proprietary ideas, though you'll hit patent issues repeatedly if you really wanted to try
[00:05:20] <cybereal> there ar eprojects for open source designs of CPUs, BIOSes
[00:05:21] <marvi> aslag: Sun has open sourced a CPU.
[00:05:38] <cybereal> the really hard core freetards are running linux on their own hardware :)
[00:05:54] <_W_> one thing you won't see any time soon; an truly open mobile phone
[00:05:57] <cybereal> of course, I tend to argue that things are often proprietary even if they're free and open
[00:06:00] <t3mp3st> marvi: hm, this stuff makes sense. I'm just not clear when a method argument should have the type of the remote interface, and when its okay to be the actual implementation type (Foobar [implements Remote] vs. FoobarImpl [extends UnicastRemoteObject])
[00:06:13] <aslag> marvi: indeed, and I'm bound to use such open-source designs or I face contradicting my values, clearly
[00:06:15] <zrunn> The Android Dev Phone 1 is pretty open
[00:06:36] <_W_> zrunn, good thing I didn't say "pretty open" then, or I'd have been wrong
[00:06:51] <_W_> on the Internet, to boot!
[00:07:00] <zrunn> well you could unscrew the screws and it would be truly open
[00:07:04] <cybereal> zrunn: and that uh openmoko or whatnot, there's everything from the bottom up hardware to software that's supposedly non-proprietary
[00:08:08] <_W_> when you come down to it, there are actual laws to prevent user control over things like frequencies and network identifiers
[00:08:20] <_W_> (partially for very good reasons)
[00:08:23] <marvi> t3mp3st: the only thing that needs to use an interface is the service class itself. Parameters and arguments works like if you run it locally. With some limits, like Serializable.

[00:13:47] <cybereal> Ven]n: that's a factor of your Look and Feel
[00:13:51] <t3mp3st> marvi: So even if a remote JVM were to use a local instance, it would use the type "FoobarImpl" and not "Foobar"? It seems like the remote thing must always use the "Foobar" since the other methods in FoobarImpl may not be remote

[00:15:54] <marvi> Foobar is the service? Yes, then the client should always use the interface. It should not even need to have the implementation in its classpath.

[01:38:35] <aslag> umm, rails is awfully n00b.  you're only saying that people, then, are n00b and you're getting close to calling yourself one
[01:38:55] <aslag> pro tip: stop doing it wrong
[01:38:55] <magmarules> aslag:  so be it, it works
[01:39:12] <marvi> runev: "images/test.gif" will use cwd from the jvm. It will depend on where you execute it.
[01:39:21] <kavon> magmarules: other than the :? operator and enhanced for loops, I've never seen a semicolon used anywhere in JAva
[01:39:24] <aslag> if by works you mean that it doesn't scale and it's slow and inflexible, sure :)
[01:41:04] <marvi> runev: try an absolute path if you want to be sure. A better solution would be to load images from the classloader with getResourceAsStream.
[01:41:10] <magmarules> kavon: sorry where did i use a semicolon? maybe i pasted something wrong =)
[01:41:13] <bobbytek2> semicolons are used all over

[03:45:02] <LumberCartel> I need to read user keystrokes, as they type them.
[03:45:13] <LumberCartel> ...as a console application.
[03:45:36] <LumberCartel> For example, if I want to write a Java version of the MS-DOS "choice.com" utility, line-buffered input is simply not suitable.
[03:47:18] *** CrypticSquared has quit IRC
[03:53:07] <LumberCartel> Well, it will be nice when Sun finally gets around to fixing this problem.  For now, it means that I have to use other languages to accomplish what I need.  I'd much prefer to do it in Java, but for now I'll just have to wait (this was a problem back with Java 1.4, and no doubt since the beginning, and Sun has had it on their to-list since 1.4 for sure).  SIgh.

[03:56:54] <LumberCartel> Java simply won't be an option if I can't do this.
[03:57:22] <LumberCartel> If there's an AWT method I can use to read the keyboard, but that doesn't require I set up a GUI, that would probably be okay.
[03:57:36] <LumberCartel> Of course I wonder if it would work on headless non-GUI Unix systems.
[03:58:33] <LumberCartel> Continuously writing to System.in from another thread would be okay as well as a kludge, I suppose, but I suspect Java's System.in won't allow that.

[04:17:22] <reverend> haha
[04:17:35] <AlanasAnikonis> lack of console IO is not a feature, it's a lack of console IO,
[04:17:37] <LumberCartel> Well, the function calls will be different, naturally (e.g., in DOS it's a matter of INT calls; in Widows it's a matter of Pascal or C calls to some DLL's functions; in Unix it's something else).  There are applications that all do this in all of these environments.
[04:18:04] <reverend> AlanasAnikonis: no, it's a lack of platform dependent support
[04:18:18] <LumberCartel> Of course I don't expect DOS to be supported, but it is an example.
[04:18:25] <LumberCartel> That doesn't seem right to me.

[05:22:10] <mztriz> If I try to use a %s as a formatting specifier, it's for a string right?
[05:22:19] *** Kwitschibo has quit IRC
[05:22:22] <AlanasAnikonis> java is so cool I think you can run the containing jar code without extracting anything, but that would probably involve a specialized classLoader
[05:22:29] *** Kwitschibo has joined ##java
[05:22:32] <juacom99> AMcBain: question did you use EditorPane's setText ot  Document's insert for that?
[05:23:10] <AMcBain> That JEditorPane is cell renderer for a JTable, so it's always setText
[05:23:20] <AlanasAnikonis> ramdam: Applications implement subclasses of ClassLoader in order to extend the manner in which the Java virtual machine dynamically loads classes.
[05:23:33] <ramdam> AlanasAnikonis, hmm, maybe i should explain. i have been having problems setting class paths lately , so i am exploring some solutions before i tackle the code tomorrow morning
[05:24:11] <ramdam> so i'm looking into that
[05:24:14] <juacom99> soemthing like EP.setText(Ep.getText()+newtext) ??
[05:25:11] <AlanasAnikonis> yes... problems are to be solved... that's usually a sound plan
[05:25:13] <AMcBain> I suppose you could do that, but the editor pane will always add the closing tags for things in it, so you're really better off trying to insert it instead.
[05:25:31] <AMcBain> (as if you just do the line you pasted, you'd end up adding that stuff after any existing closing tags)
[05:25:37] <ramdam> i'll also be trying this http://java.sun.com/j2se/1.3/docs/tooldocs/win32/classpath.html
[05:25:48] <ramdam> as well as making an installer

[05:28:05] <svm_invictvs> Which is why I like the idea of printed logs.
[05:28:10] <svm_invictvs> You can't falsify them very easily.
[05:28:27] <AlanasAnikonis> poor squirrels and their precious trees :'(
[05:28:29] <svm_invictvs> I just wish such a thing didn't waste paper.
[05:28:57] <thunderbolt> I thought there were append-only hardware things you could plug into servers instead of printing logs.
[05:29:05] <svm_invictvs> Yeah, I woudl think so.
[05:29:09] <svm_invictvs> That would be pretty cool.
[05:29:32] <svm_invictvs> Append only, but to erase from them you'd have to physically remove them and put them in a separate device.
[05:29:46] <thunderbolt> Yeah.

[06:20:03] <javawizard2539> I agree
[06:20:04] <svm_invictvs> iirc, there's no direct API to it in java
[06:20:09] <javawizard2539> Correct
[06:20:26] <javawizard2539> So I can't tell what manunderground wants to do but it looked kinda like he wanted to use the windows registry for something

[06:23:54] <jcp> but one of it's strong points is it's platform independence

[07:30:29] <r0bby_> ScottG489: make this into a swing app
[07:30:41] <r0bby_> actually
[07:30:44] <r0bby_> take your logic here
[07:30:56] <r0bby_> put it in a small test app
[07:30:58] <r0bby_> run it
[07:31:03] <r0bby_> does it output correctly?
[07:31:09] <ScottG489> I dont follow what you mean.

[07:32:33] <ScottG489> I mean I put all of the getTexts into each part of the array. Then i accumulate the values of each into "average" then i set averages value to the answer label

[07:37:32] <ScottG489> now that I think about it i think I know why
[07:37:46] <pilkarn> so is jmf a media playe? <- hello that was a joke
[07:38:02] <r0bby_> pilkarn: it's kind of hard to guage this
[07:38:03] <ScottG489> r0bby_: Which acually comes right to my next question on how to be able to hit enter when the user is on the last text box and be able to submit it
[07:38:15] <r0bby_> FocusListener.
[07:40:21] <ScottG489> r0bby_: addActionListener works too
[07:40:47] <ScottG489> thats why i was confused. Because the user can hit enter when they are on the final field and it will calculate it for them
[07:41:50] <ScottG489> I'm still pretty impressed I was able to figure all of this out. I don't like how I got the input for the array which kind of defeats  the purpose but I have a feeling that doing it the correct way is more advanced

[08:19:07] <deebo> ive just stumbled onto some stuff that actually doesnt work crossjre
[08:19:13] <deebo> so there might be an actual reason for it
[08:19:16] <gandalfcome> thanks AlanasAnikonis and others
[08:19:20] <Ben_Cs> does the garbage collector destry a Vector object, when all references to that object point to null. or is it required for the Vector object to be empty also?
[08:19:35] <deebo> Ben_Cs: it will be gc'ed when nothing references it
[08:19:53] <Ben_Cs> deebo: even if it's not empty?
[08:19:57] <AlanasAnikonis> there is a big chance it will be gc:ed
[08:20:04] <deebo> doesnt matter
[08:20:13] <gandalfcome> deebo: well i hope it works, I just need to use it for a little while
[08:20:15] <Ben_Cs> ok, thanks
[08:20:15] <deebo> or well, actually im nto sure if something INSIDE it is referenced
[08:20:26] <AlanasAnikonis> well I was gonna say just that
[08:20:33] <AlanasAnikonis> if it has elements that are referenced....
[08:20:54] <AlanasAnikonis> then the vector must exist somewhere
[08:20:54] <deebo> so lets rephrase: it will get gc'ed if it and its contents are not referenced
[08:21:02] *** LostMonarch has joined ##java
[08:21:09] <AlanasAnikonis> sounds better

[08:48:49] <pr3d4t0r> jhujhiti: if (c instaceof Whatever)
[08:49:11] <pr3d4t0r> jhujhiti: And you don't check the type of T directly.  That's the whole point of having parameterized types.
[08:49:11] <jhujhiti> pr3d4t0r: the problem is i don't actually have a reference to anything of that type
[08:49:14] <jhujhiti> all i have is the type
[08:49:34] <jhujhiti> i'm trying to use the type as a hint for how large to make an array

[08:55:06] <pr3d4t0r> jhujhiti: If you yourself don't know at compile time what you're passing to your objects, neither does the compiler.
[08:55:23] <jhujhiti> pr3d4t0r: *I* know
[08:55:32] <pr3d4t0r> jhujhiti: The only way of checking types, then, is to add instanceof or a similar check.
[08:55:57] <jhujhiti> pr3d4t0r: i have the generic Length parameter there so i can pass it, for example, a Byte. so the length should be one byte long in the array
[08:56:39] <pr3d4t0r> jhujhiti: Read what I said.  Read about parameterized types in Java (generics).  Then decide if it can be done or not.

[11:02:06] <m4rtijn> what is a more conventional method for testing unassigned vars in a custom class?
[11:02:24] <m4rtijn> I could just set them to null.. in the main constructor
[11:02:30] <m4rtijn> and test for == null
[11:02:38] <m4rtijn> or should I use class forname
[11:03:18] <fr0ggler> use null - forname is usually only for reflection stuff
[11:03:51] <m4rtijn> so thats a common method?
[11:03:55] <m4rtijn> setting to null
[11:04:05] <fr0ggler> if you're just checking if an object has been instantiated, then checking for null will suffice
[11:04:28] <m4rtijn> but I do have to set it before.. or not
[11:04:50] <dangertools> m4rtijn: fields of reference types are always initialized to null. no need to do that again in the constructor
[11:04:52] <fr0ggler> so something like ArrayList<String> stringList;
[11:05:04] <fr0ggler> what dangertools just said :D
[11:05:19] <m4rtijn> thanks dangertools

[11:13:10] <m4rtijn> one more.. bit noobie question..
[11:13:40] <m4rtijn> If I know I need some kind of array or List in my class.. and I know this List won't be searched often and wont get very big
[11:13:56] <m4rtijn> is it better to use a normal array instead of List or Vector?
[11:14:08] <cybereal> better for what?
[11:14:33] <cybereal> without a more specific scenario a real answer can't be made, however, a generalization can be and that would be "Use List"
[11:14:47] <fr0ggler> if you're doing search operations on a data structure, then list is probably better
[11:15:20] <fr0ggler> the search methods are optimised quite well for Lists, and have nicer convenience methods than standard arrays

[12:40:13] <fr0ggler> ciphergoth: why not write a java class that you can just include in your JSP?
[12:40:36] <ciphergoth> fr0ggler: I could but it's so much more heavyweight than seems appropriate for the problem
[12:40:45] <fr0ggler> depends what the problem is :D
[12:40:57] <fr0ggler> jsps are meant to be written in that way
[12:41:12] <ciphergoth> All I want to do is <img width="12" height="12" src="thingy.png" title="<insert title here somehow>"/>
[12:41:25] <ciphergoth> so it's just got one parameter, the title, and it spits out that little bit of URL
[12:41:37] *** DragonLord- has joined ##java
[12:41:40] <ciphergoth> I can't believe the cleanest, neatest solution that makes the best use of my tools is to write that in Java
[12:41:40] <fr0ggler> and where do you want to get the title from?
[12:41:46] <ciphergoth> it's a string when I call it
[12:42:11] <ciphergoth> so I'll want to say <something:insertsomething text="use this title at this point"/> in various places
[12:43:19] <fr0ggler> so write your own tag that insert the image with your desired text? i don't really see where you're getting your dynamic title text from...
[12:43:52] <ciphergoth> it's a literal in the JSP that's calling my thingy
[12:43:57] *** cher has joined ##java
[12:44:30] <fr0ggler> ok so you have a member variable in your JSP?
[12:45:01] <fr0ggler> like String myText = "blah"; and then you do ...title="{myText}" ?
[12:45:13] <ciphergoth> fr0ggler: not yet (I tried a different approacj that didn't work) but that's probably part of the right solution
[12:45:46] <ciphergoth> if I did that, what would I do next to call it?
[12:45:55] <fr0ggler> you do realise that JSPs get compiled into servlets, so using Java inside them isn't considered "dirty" ;D
[12:46:02] *** ircozzy has joined ##java
[12:46:06] <fr0ggler> how do you meant "call it"?
[12:46:16] <ciphergoth> use it, reference it, have it do its thing
[12:46:43] <ciphergoth> I consider using Java inside JSPs dirty anyway
[12:46:55] <ciphergoth> I like my Java where Eclipse can see it
[12:47:15] *** casmo has quit IRC
[12:47:54] <ciphergoth> what you're saying about member variables sounds promising
[12:47:56] <fr0ggler> JSPs are Java.... but anyway...
[12:48:18] <ciphergoth> JSPs are compiled into Java, sure
[12:48:59] <fr0ggler> you can use member variables in script by doing something like ...title="<%= variableName %>"
[12:49:34] <fr0ggler> so you're just using inline Java scriptlets

[12:54:19] <ciphergoth> so there'll be one JSP that says <some:tag ... title="this"/> and later <some:tag ... title="that"/>
[12:54:51] <ciphergoth> and my thingy should be called twice, with a different parameter at each point.  (I know that "call" and "parameter" isn't the right vocab here but not sure what is)
[12:57:22] *** dnmo has joined ##java
[12:58:15] <fr0ggler> ok so are these tags your own custom ones? attributes in tags relate to getters and setters in your tag definition
[12:58:42] <ciphergoth> I don't mind whether the tag is custom by me or from a taglib that does what I want
[12:58:44] <gfather> do u think reading more books will improve your java skills , or practicesing  more will do that ?
[12:58:50] <fr0ggler> so title="this" would refer to your tags setTitle method
[12:59:46] <ciphergoth> that's one way forward, but it sounds like I'd have to write my own taglib in Java to do that
[12:59:47] <fr0ggler> it totally depends on how you want to populate the title attribute, e.g. from a backend database, from a tiles definition, from a data object method...
[12:59:57] <ciphergoth> none of the above
[13:00:02] <fr0ggler> ok, from where then?
[13:00:03] <ciphergoth> from a literal in the calling JSP
[13:00:30] <fr0ggler> and where do you set that literal?
[13:00:34] <ciphergoth> it's as simple as this: I've got the same thing repeated in this one JSP fiile over and over again
[13:01:17] <ciphergoth> there's one point where the JSP file says <img width="12" height="12" src="long/path/name/thingy.png" title="title of the first instance">
[13:01:30] <ciphergoth> and then later on it says <img width="12" height="12" src="long/path/name/thingy.png" title="title of the second instance">
[13:01:38] <ciphergoth> and there's a third, a fourth, a fifth instance
[13:01:43] <ciphergoth> so that's a lot of repetition in my JSP
[13:01:48] <fr0ggler> sure
[13:01:55] <ciphergoth> and I want to work out how not to repeat myself.  That's all
[13:02:09] <fr0ggler> so i refer back to my very very first suggestion of writing a java method
[13:02:17] <ciphergoth> seriously?
[13:02:28] *** hoerup has joined ##java
[13:02:51] *** mmc has left ##java
[13:03:20] <ciphergoth> there's no taglib that makes this easy for me already?  It doesn't seem like such an unusual or strange need/
[13:03:28] <fr0ggler> so <% getImgWithTitle(String title) { out.write("<img ........ title="+title+"/>"); } %>
[13:03:40] <fr0ggler> yeah there probably is - im not going to go look for that for you :)
[13:03:57] <fr0ggler> (i don't know if out.write is correct, but you get the idea)
[13:04:49] <ciphergoth> fr0ggler: if you've any suggestions on where to look I'm happy to do the looking ;-)
[13:05:18] <fr0ggler> without sounding harsh, Google would be a good place to start.  Seriously.
[13:06:08] <ciphergoth> oddly enough, I tried that :-) but maybe I chose the wrong search terms?  What search terms might you suggest?
[13:06:15] *** Ven]n has joined ##java
[13:06:17] <fr0ggler> although why you'd want a taglib outputting a simple html fragment with a per-use defined string is beyond me
[13:06:42] <fr0ggler> when you can do it in "normal" java
[13:06:48] <fr0ggler> but hey, each to their own :)
[13:07:15] <fr0ggler> http://struts.apache.org/1.x/struts-taglib/tlddoc/html/img.html

[13:50:36] <milligan_> Stupid question, but what's the difference between extends and imeplements ?
[13:50:42] *** ankylose has joined ##java
[13:50:49] *** indeterminatus has joined ##java
[13:50:50] <FauxFaux> One is for classes, the other is for interfaces.  Normally.
[13:51:04] *** blankthemuffin_ has joined ##java
[13:51:21] <milligan_> ah, ok.
[13:51:34] <milligan_> And what differs an interface from a class ?
[13:51:42] *** Level1 has joined ##java
[13:51:53] <FauxFaux> It can't have method bodies or member variables.  Your book probably tells you this.
[13:52:04] <elmomalmo> jo4: You might find this codeswarm wiki page useful. http://code.google.com/p/codeswarm/wiki/RunOpenGL
[13:52:05] *** |sanchez| has quit IRC
[13:52:07] *** deepjoy has joined ##java
[13:52:14] <fr0ggler> milligan_: interfaces are for describing just that - an interface for implementing classes to adhere to
[13:52:38] <Level1> hi, I'm trying to use a gridlayout, but when I have enough columns or rows, it seems to force it to one less column than I specified, creating this weird diagonal effect
[13:53:01] <elmomalmo> jo4: Especially the bit about LD_LIBRARY_PATH
[13:53:52] <milligan_> fr0ggler, so an interface will just a collection of classes that it extends?
[13:54:03] <fr0ggler> FauxFaux: interfaces can have member variables, but they are implicitly final
[13:54:37] <FauxFaux> fr0ggler: Not very variable. >.<
[13:54:43] <fr0ggler> milligan_: no, classes will implement interfaces so you know that those classes must implement some base functionality as set out by the interface
[13:55:01] <fr0ggler> FauxFaux: no, but you can still have them
[13:55:19] <fr0ggler> FauxFaux: useful for constants or enums etc
[13:55:43] <benJIman> I believe it's referred to as an antipattern.
[13:55:52] <FauxFaux> I don't see how it's useful for enums, unless you mean pre-java5.
[13:56:30] *** Greyhound- has quit IRC
[13:56:34] <fr0ggler> FauxFaux: you can specify an enum that will be accessible for all implementing classes
[13:56:38] *** cyzie has quit IRC
[13:56:59] <benJIman> fr0ggler: It's a very bad idea for several reasons, and why import static was introduced (so you don't need to do it)
[13:57:30] *** Greyhound- has joined ##java
[13:57:50] <fr0ggler> they aren't mutable, so are fine as final member variables in interfaces - true benJIman, but FauxFaux was wrong is saying that you CAN'T have member variables in interfaces
[13:57:59] <fr0ggler> but anyway, this isn't helping milligan_ at all is it
[13:58:12] <FauxFaux> HEavily depends on your definition of VARIABLE.
[13:58:12] <benJIman> http://java.sun.com/j2se/1.5.0/docs/guide/language/static-import.html
[13:58:38] <fr0ggler> christ - don't get all lexically facetious on me
[13:59:34] <milligan_> hehe - quite a bit of meat on that bone to chew, that's for sure.
[13:59:58] <fr0ggler> milligan_: so for example, say you write an interface Inflatable that says that all implementing classes have to have an "inflate(int amount)" method
[14:00:27] <fr0ggler> then you write a Balloon implements Inflatable class
[14:00:33] <milligan_> So .. an interface will be a description of "stuff" that is required.. and if my class implements the interface, it won't compile unless I have the methods the interface describes ?
[14:00:39] <fr0ggler> exactly ;)
[14:00:48] <milligan_> yeah .. nice :)
[14:02:16] <paulweb515> milligan_: yes, an interface is a contract ... any class that implements the interface (correctly) fulfills the contract, and can be used where that interface is needed

[14:30:23] <toader> I want to see how much memory consumed when i runing java
[14:30:28] <jottinger> m4rtijn: yes... but the JVM defines the sizes of types explicitly.
[14:30:40] <m4rtijn> the 64 bit float of Date() will go on for 18billion more years
[14:31:06] <m4rtijn> I guess I dont have to change my app in 18 billion years anymore..
[14:31:19] <jottinger> Well, you will, but not because of THAT
[14:31:38] <m4rtijn> heh
[14:31:48] <reverend> hopefully mostly everything will be rewritten in a billion years or so

[15:12:53] <ExtremeDevilz> not that i want it
[15:12:59] <cheeser> because when the copyright holders come to ream out your ass, they'll collect all the evidence of infrigement they can.  and that includes chat transcripts.
[15:12:59] <ExtremeDevilz> i tried to search like mad
[15:13:08] *** skoskav has quit IRC
[15:13:13] <fr0ggler> so you search like mad for source code you don't want?
[15:13:27] <fr0ggler> seems a little futile to me
[15:13:31] <ExtremeDevilz> o.o
[15:13:43] <ExtremeDevilz> no you dont understand

[15:14:17] <ExtremeDevilz> like HexTools Etc .
[15:14:31] <fr0ggler> then speak to the original developers
[15:14:33] <cheeser> so email one of those students.

[15:32:47] <isr`> okay, so this is a design question. if i have some class, Model that i want to flatten to text to save to/open from a text file, does it make more sense to create one helper class that provides static methods to save a Model instance and to open a Model instance from a text file
[15:32:58] <isr`> or would it make more sense to split those operations into two separate helper classes.
[15:34:14] *** fanti has joined ##java
[15:34:15] <isr`> so, TextModel.save(Model m, File f)   and TextModel.open(File f), or ModelToText.doIt(Model m, File f) and TextToModel.doIt(File f)
[15:35:00] <isr`> i think perhaps because i am using the same delimiters in either case, it might be better just to use one class to perform both operations
[15:35:26] *** h-kan has left ##java

[15:35:42] <fr0ggler> either way sounds fair enough really
[15:35:51] <fanti> hello! i like to know whether the jdbc mysql-connector driver releases the CPU in a multithreading system so that other threads can run while waiting for a query answer?
[15:36:17] <jottinger> fanti: if it's in java, it doesn't have much of a choice
[15:36:34] *** waz has quit IRC
[15:37:06] <dmlloyd> yeah, you have to go out of your way to write something that comsumes CPU needlessly
[15:37:09] <dmlloyd> consumes*
[15:38:51] <fr0ggler> isr`: it's probably just down to taste - you could have a ModelIOFactory class with a member Model variable that gets set on construction telling the factory what type of model you want to perform operations on (TextModel in this case). The saveModel and loadModel methods would call model.save and model.load
[15:39:00] <fr0ggler> something like that would be nice and easy to understand
[15:40:08] <isr`> fr0ggler: yeah, but the model is put together in a non-trivial way during run time sometimes.
[15:40:17] <isr`> i see what you are saying though.
[15:40:40] <isr`> basically this app is using the java compiler to reverse engineer java code.
[15:40:56] <isr`> pretty useless really, but it is interesting
[15:41:21] <fr0ggler> well that should still work.  construct your model, init your ModelIOFactory with the completed model, and call factory.save
[15:41:52] <isr`> word
[15:42:01] <fr0ggler> but as i say, it's totally down to taste - there's no real "right" way of doing what you want

[17:01:11] <vol> Yes, use a static object.
[17:01:14] <vol> ~static
[17:01:14] <javabot> vol, static is a keyword which indicates that a member is scoped to a class rather than an object instance.  Members of interfaces (except methods) are always static.

[17:12:17] <juacom99> Hi
[17:12:33] <juacom99> AMcBain: rememaber the porblem i got yesterday?
[17:12:45] <AMcBain> er sorta.
[17:12:55] <AMcBain> (you caught me while I was actually here, wow)
[17:12:55] <juacom99> AMcBain: i think i found the porblem...
[17:13:04] <juacom99> lol
[17:13:37] <AMcBain> well, are you going to finish your thought?
[17:13:44] <juacom99> http://paste.ubuntu.com/121924/
[17:13:53] <juacom99> tht's the porblem
[17:13:56] <fr0ggler> chanux: good luck then ;)
[17:14:05] <juacom99> is parsing my < quotes and >
[17:14:14] *** prgrmr has quit IRC
[17:14:45] <AMcBain> huh? what? *what* "is parsing [your] < quotes and >"?
[17:15:13] *** zophy has quit IRC
[17:15:42] *** shadewind has quit IRC
[17:15:56] <juacom99> when i insert ( i can'r use setText cos' it append the text afther the </body> tag) the document change my " for $quote; for example
[17:16:04] <juacom99> that's why is not parsing it

[17:17:59] *** steve-e has quit IRC
[17:19:09] <juacom99> how much oveheas will add that ?? :S
[17:19:14] <AMcBain> (it seems stupid from an efficiency point of view to get the text, remove something you didnt' want it to add in the first place (the remaning closing tags) add your stuff to it, then send it all back in ... but what can you do? they want you to have proper html)
[17:19:23] <AMcBain> remaining*
[17:19:29] *** genesiss has quit IRC
[17:19:58] *** casmo has joined ##java
[17:20:29] <AMcBain> personally though, I'd just do it and not worry about any "overhead" or slowdowns until you actually see some and can trace it back to that.
[17:21:04] <AMcBain> so basically, go for it, then fix efficiency concerns *later* /after/ they appear (because they might not, and in which case, you don't need to do anything)
[17:21:35] *** riotz has quit IRC
[17:22:04] <juacom99> ok
[17:22:09] <juacom99> i'll try that
[17:23:07] <AMcBain> I mean, you saw the output for my client ... I do a regex and loads of parsing on each incomming line. if I'd thought "this could be inefficient" and tried to fix it before I even figured out if it really cost anything, I'd have ended up with something that was probably twice as complicated and doesn't work/.
[17:23:20] *** chanux has quit IRC
[17:23:41] <AMcBain> (in the end, each line is a max of 255(?) characters or less, so I really don't have to worry so much per line)

[18:19:48] <cheeser> ~newbie ide
[18:19:48] <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.

[18:58:20] <svm_invictvs> Friday.
[18:58:44] <Sonderblade> _W_: that advice is not good, generic classes like Pair are very useful which is why they exist in virtually all languages, it is just java that is lacking in this.
[18:58:49] <jottinger> Coming this friday? or last friday?

[18:59:41] <fugolini> Hi, a big question, why I'm able to edit file (e.g. xml) while I'm working on NB and then when I jarred it, I get a lot of exception like I didn't find the file (i'm using getresource() to retrieve resources)
[18:59:43] <fugolini> ?
[18:59:57] <Sou|cutter> Sonderblade: Actually I think that advice is good
[19:00:16] <svm_invictvs> I was sitting there with the HR lady, and I just wanted to break out in the "Carl" voice and say, "So...uh...Are we done here?  Is that all you had to say?"
[19:00:33] <_W_> Sonderblade, they're useful if you've got something which does something with generic pairs... which you almost never do
[19:00:41] <Sou|cutter> Sonderblade: And, as demonstrated, writing your own is pretty trivial
[19:01:13] <_W_> instead you have something that does something with key-value pairs, or that does something with coordinates, or that does something with a base number and a power, etc
[19:01:33] <fugolini> Is there any possibility to let jar working like a normal file directory or, have I to move to another Planet (maybe Mars)?

[19:19:39] <Sonderblade> blahjake: could yes, but your solution is more complicated
[19:19:41] <isr`> yeah
[19:19:54] <isr`> lem im not sure why you are separating it like that.

[19:35:31] <pgib> Hello. I have a set of classes where each handles a specific request from a servlet (or possibly any source in the future).  We also have an Enumeration that lists all the different Actions.
[19:35:36] *** joeo is now known as jottinger
[19:35:48] *** blipX has joined ##java
[19:35:51] <jottinger> pgib: so you're using Struts?
[19:36:02] <pgib> I'm wanting to map the action to a handler class to delegate the work.  I could use a Map at the Servlet level
[19:36:20] <jottinger> but struts already does that...
[19:36:27] <pgib> jottinger, no, this is my own thing.  The servlet has grown too large, so I refactored the different actions to different objects
[19:36:32] <jottinger> or you're using spring mvc? No, because HAT already does that too
[19:36:41] <pgib> ok, but we aren't using spring or struts
[19:36:42] <blipX> Trying to figure out why a java app a user is using doesnt appear to be decoding things like return, backspace and delete. Is this a setting that can be passed to apps, has to be done in the app or a jre or similar setting?
[19:36:42] <jottinger> or you're using wicket? No, wicket does that too
[19:36:47] <pgib> ??
[19:36:55] <jottinger> or stripes? or echo? no, those do that sort of thing for you too
[19:36:59] <jottinger> wait, let me get this straight
[19:37:02] <jottinger> you WROTE THIS?
[19:37:03] <jottinger> Yourself?
[19:37:10] <vol> oh god, what a terrible idea
[19:37:12] <vol> writing something
[19:37:14] <pgib> I'm confused
[19:37:17] <jottinger> vol: no
[19:37:21] <jottinger> writing something is no big deal
[19:37:38] <jottinger> writing something that is a poor version of what well-established frameworks do, THAT's a problem
[19:37:48] <vol> you're right, he should refactor his mature codebase to shove in something similar instead.
[19:37:53] <jottinger> anyone who rewrites Struts today ... wrong move
[19:38:08] <jottinger> vol: maybe it's me, but I'm thinking his problem is an indicator of a lack of maturity
[19:38:18] <pgib> I guess my question has no validity due to your opinion on architectures
[19:38:20] <jottinger> of the codebase, that is
[19:38:24] <vol> or an old codebase, from before when struts/etc were popular?
[19:38:27] <pgib> we aren't using struts, sorry
[19:38:31] <pgib> oh well. I was going to ask for an opinion on where to put the actual mapping of action -> handler.
[19:38:34] *** ofl_ has joined ##java
[19:38:35] <jottinger> vol: that'd be back in 1999 or so :)
[19:38:44] <vol> yeah, which is pretty much what the code at my last company was.
[19:38:47] <jottinger> pgib: depends on how the servlet's invoked.
[19:38:47] <pgib> I could create a map or similar factory at the servlet level
[19:39:05] <jottinger> pgib: use a context listener, store the map in the application context
[19:39:16] <pgib> or, I could perhaps have a  boolean handles() function or similar in the handler objects themself
[19:39:17] <vol> moderately mature code in a culture quite averse to sudden radical changes due to a skittish customer list
[19:39:21] <jottinger> but seriously, if this isn't, like, really old and expensive code, use something else
[19:39:29] <pgib> but.. I'm thinking the first alternative would be more flexible
[19:39:38] <vol> the world doesn't always involve best practices : (
[19:39:40] <jottinger> vol: NIH is usually an unwise approach
[19:40:03] <vol> well, more like "invented seperately and we don't want to screw with what works"
[19:40:14] <pgib> It's more of evolution

[19:41:12] <vol> to be fair, jottinger is probably right
[19:41:22] <vol> if this is going to continue growing, pgib, you should probably take the plunge
[19:41:32] <pgib> Rather not have to inherit a new framework at this point, especially considering everything works. I was just wondering if it makes sense to glue the action-to-handler at the individual handler level or at a more macro level
[19:41:34] <The_Birdman> pgib: If the codebase isn't huge and you can integrate a framework if it doesn't take much time. Here I'm dealing alone with an application which is big and 10 years old. Migration and refactoring isn't much an option
[19:41:36] *** Bevin has joined ##java
[19:42:17] <pgib> We use wicket for our pages,  but this is for a highly-specialized webservice that interfaces to a javascript widget we have
[19:42:41] <The_Birdman> ah
[19:43:14] <The_Birdman> If I could use wicket here, I would be happy, I am dealing with that plain old struts
[19:43:45] *** blipX has left ##java
[19:43:47] <The_Birdman> and 200 000 lines of code, it's ugly
[19:43:51] <pgib> yes.. but from what I understand about struts, it isn't really what we need. not for this anyways
[19:44:10] <The_Birdman> it wasn't really related to your problem, just speaking my mind :-)
[19:44:11] <pgib> the problem I'm solving right now doesn't involve pages or view really.  It is all RPC
[19:44:22] <pgib> The_Birdman, understood
[19:45:12] <juacom99> argg i hate JEditorPane :@
[19:45:21] <pgib> Anyways, since I can't get a straight answer regarding the actual design of the system I'm going to be working with: I'm going to handle the mapping at a level macro to the Handlers themselves:
[19:45:48] <pgib> I.e: A map of Actions to Handlers instead of looping over the Handlers calling handler.handles(action);
[19:47:11] <vol> probably reasonable
[19:47:29] <svm_invictvs> hm
[19:47:31] <The_Birdman> pgib: Why would you loop over handlers?
[19:48:12] <pgib> I mean, it is Java's Listener layout for the most part
[19:48:16] <The_Birdman> I also deal with RPC and I don't loop over handlers, at some places we have classes with handlers' constants for names and some maps
[19:48:47] <pgib> We have around 30 different actions
[19:48:58] <The_Birdman> I am dealing with about 100
[19:49:09] <pgib> OK cool.  So, we have a handler-per-action
[19:49:43] <pgib> The thing is, the requests comes in with a parameter, action=createUser for example.  We get the enum for this action
[19:50:07] <pgib> Then need to execute the proper handler.  Either, at this level, we have a map or a big if/else to call the proper handler
[19:50:20] <pgib> Or, the list of handled actions can be stored in the Handler itself
[19:50:34] <pgib> How do you delegate to the proper handler?
[19:50:43] <jottinger> use a map
[19:50:45] <The_Birdman> Using a map
[19:50:53] <vol> hardcode the class name with the action.

[20:17:20] <TryNiX> hi all. I have a problem, where basically I got a quad tree, and I need to 1) store a value related to leaf nodes (i.e. a value that is calculated through the 4 leafs), and (2) once all of these values are calculated, values are then sorted, and the parent nodes which have 4 leaf child nodes having the least value, is deleated
[20:17:36] <srart> why would this fail?   test=Integer.parseInt(serverInput.substring(0,4));
[20:18:01] <vol> serverInput is null

[20:18:24] <TryNiX> I am thinking of using two linked lists, one to hold the values and the other to hold the arrangement of objects that the values corrsepond to, but when sorting the values, how can I sort both the values arrangement linkedlist, and the corresponding object arrangement linkedlist?

[20:25:44] <srart> kind of fragil, any better way to get a match for a substring? (find I would imagine)
[20:26:26] <letfunbegin> srart: I don't know what it's for (what you need exactly), but I've always found regular expressions to be the more stable solution
[20:26:35] <letfunbegin> it certainly gives you more control at least
[20:26:42] <tds5016> File fpSDPFile = new File(filePath);
[20:26:42] <tds5016> 			fpSDPFile.createNewFile();

[21:38:25] <ernimril> Zvpun: as the edt tutorial tells you, do not mix slow operations (like io) with swing
[21:38:34] <Zvpun> ernimril: I am still reading the information you gave me, may I ask what rule I broke? calling sytem?
[21:39:16] <ernimril> Zvpun: the thread that calls main(...) is not the edt
[21:39:33] <ernimril> Zvpun: so creating a gui from that thread is a big no-no
[21:39:36] <LordMetroid> Can one use a defined generic to instantiate an object?
[21:40:02] <ernimril> LordMetroid: you can not do "new T()", if that is what you are asking
[21:40:11] <Zvpun> ernimril: that is public main() { new JFrame(); } is very bad?
[21:40:19] <ernimril> Zvpun: yes
[21:40:40] <ernimril> Zvpun: it will randomly crash your jvm or randomly hang it or randomly work
[21:40:41] <Zvpun> ernimril: okay I try to find that in the docs that you gave me.
[21:41:55] <LordMetroid> ernimril, what if T is defined as <T extends Foo> ?

[21:42:37] <Zvpun> ernimril: Thank you
[21:42:44] <LordMetroid> Maybe I need to remake the T class to an interface
[21:42:58] <ernimril> LordMetroid: it can not be done, pass a "Factory<T>" as well (can in a few cases be Class<T>, but typically easier to use a real factory class)

[22:20:04] <ernimril> krad: well, the classloader will look inside it before it check the second jar file, that may be an advantage
[22:20:20] <ernimril> TryNiX: define: initialized
[22:20:44] *** monkeycid has quit IRC
[22:20:56] <krad> yup.. so if the first has a mainfile defined in the second as well.. the first will be loaded.. otherwise i'll have to put the second jar the first on the classpath to make that mainfile loadable

[22:23:46] <TryNiX> So if for example I am comparing distances and wanting to store shortest distance in d, is it best to set d as negative in the start, then see if its negative and set it as current distance? otherwise compare if current distance is less than d?
[22:24:19] <cheeser> well, 0 is never less than a negative number.
[22:24:32] <ernimril> TryNiX: I would probably set to Double.MAX_VALUE and just set the value to Math.min(current, newValue)
[22:25:17] *** Spike1506 has quit IRC
[22:25:25] <pgib> TryNiX, I would probably just keep a boolean around if you are trying to determine if the path exists

[22:26:10] <elaltaico> which it can work in other place except dist  directory ?
[22:26:34] <ernimril> jhujhiti: Class.hashCode just uses Object.hashCode
[22:26:34] <pgib> elaltaico, it is probably in your best interest to learn how to build jars yourself first if you don't already know that
[22:27:09] <cheeser> ~~ elaltaico newbie ide
[22:27:09] <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.
[22:27:40] <elaltaico> pgib i can build them by shift+11 and it works under dist directory well.but they do not work outsife of dist directory..
[22:27:46] <elaltaico> which configurations i need to do with manifest?
[22:27:56] <pgib> elaltaico, I mean with javac and jar
[22:27:58] <ernimril> ~~elaltaico jar
[22:27:58] <javabot> elaltaico, jar is Java ARchive See  http://java.sun.com/tutorial/jar and http://java.sun.com/javase/6/docs/technotes/guides/jar/index.html Also see fatjar and jarjar
[22:28:08] <pgib> or at least ant
[22:28:13] <elaltaico> well..
[22:29:13] <jhujhiti> ernimril: so it's based on the address. does that mean that two Class<Byte> will always have the same hash code?

[22:29:25] <elaltaico> i know what is jar :) my question is that..my question is i'm able to make runnable jar file on netbans and my desktopallication2.jar works fine under dist directory..but if i copy paste it somewhere it does not work.
[22:29:41] <ernimril> jhujhiti: why do you need to know? and why do you have two Class<Byte>?
[22:29:51] *** monkeycid has joined ##java
[22:29:56] <jhujhiti> Byte was just an example

[22:30:09] *** elaltaico has quit IRC
[22:30:10] <ernimril> elaltaico: so unpack it, check what is missing and fix the problem

[22:30:21] *** djp[mbp] has joined ##java

[22:30:34] *** poxus has left ##java
[22:31:01] <ernimril> jhujhiti: Byte is in package java.lang so you should not try to load two different versions of it, it will cause problems
[22:31:15] *** yrlnry has joined ##java
[22:31:33] <ernimril> jhujhiti: if you have two different Class<your.own.ClassName> then they have been loaded by two different class loaders
[22:31:44] <jhujhiti> that's not what i'm trying to do
[22:32:05] <ernimril> jhujhiti: consider asking your real question
[22:32:24] <jhujhiti> this all started when i needed an enum that was extended something
[22:32:35] <jhujhiti> which i can't do, as i understand it, because enums already inherit Enum
[22:32:43] <ernimril> jhujhiti: correct
[22:32:43] <cheeser> enums extend Enum
[22:32:55] *** krad has quit IRC
[22:33:06] <jhujhiti> so i'm trying to write a class to model an enum that acts like an enum
[22:33:36] <jhujhiti> i'll pastebin an extremely naive implementation in a few minutes
[22:33:39] <ernimril> jhujhiti: if you want an enum you should use an enum
[22:33:45] *** monkeycid has quit IRC
[22:34:05] <jhujhiti> ernimril: i need a common base class for my enums

[23:12:21] <BlueLaguna> Does anyone know where I can find a more aesthetically pleasing javadoc?
[23:12:28] <BlueLaguna> Preferably with ajax?
[23:12:46] <dmlloyd> BlueLaguna: what you're looking for will be called a doclet
[23:12:58] <arakthor> what are the possible methods for passing data between threads?
[23:13:00] <dmlloyd> google for "ajax doclet" and I'm sure you'll find something
[23:13:08] <dmlloyd> ~~ arakthor jcip
[23:13:08] <javabot> arakthor, jcip is Java Concurrency In Practice, a book focused on implementing threaded and concurrent applications in Java.  http://jcip.net/
[23:13:12] <BlueLaguna> dmlloyd: thanks
[23:13:51] <arakthor> thanks dmlloyd \
