<0> hi^^
<0> theres any IBM IDE to develop J2EE Applications ?
<0> or websphere apps
<1> yes
<0> wich? i just download the wasce
<2> hey talios
<2> I know a company in Auckland looking for developers etc
<3> My bro
<3> 's in the market looking around wellie at the moment
<4> hello
<4> if i have a number of cl***es in a package structure
<4> and i want to compile all of them..
<4> can i p*** the package structure to javac or do i need to specify a particular cl*** to compile?
<4> say the package com.myco.ui has 10 cl***es
<5> hello
<6> morning gilead.
<6> MrBooerns werent u in discussions all of yesterday about that.
<6> that information can all be found via a quick google
<5> Deano: what's the discussion about?
<6> compiling java cl***es; specifically a complete package
<5> ah
<6> wb wlfshmn.
<7> so ironic
<7> the creator of these laguages
<7> like c, c++
<7> they should be the richest man in the worl
<7> but bill gates is the richest
<8> i have to create an app which contains a frame and menus. When i select a a menuitem the content of the frame changes everytime. How can i manage the different contents?
<8> i tried with a jlayeredpane but when i click an object from a back pane it brings it to front :(
<8> any suggestion?
<7> dls-128: try netbeans
<7> the latest version
<8> i am using netbeans 5.0 but i don't know how to start :(
<7> read
<8> i have a timelimit :(
<8> it's possible with JLayeredPanes?
<8> *pane
<7> yes
<8> and how can i make the objects from backworj unselectable?
<8> backword*
<7> use some listeners
<7> actionlistener
<7> etc...
<7> read the java tutorial for swing
<7> and get the Java API .chm
<8> listen to what, because at this moment they have no listeners and they bring to front in the first pane
<8> can u offer me a link to that chm?
<7> then implement some listeners
<6> just use the java api via html on sun's site
<6> google for java api.
<7> http://www.allimant.org/javadoc/jdk15e.html
<7> get the .chm format
<7> .hlp sux
<7> .chm works on Mac or linux too
<6> thats because its html.

<12> anyone knows here j2me
<12> i've got a lil question i just downloaded sonyericsson j2me sdk 2.2.3 and it has a small package called com.sonyericsson wich contains a few clases
<12> couldn't find any javadocs on them
<12> and i was wondering if anyone knows what are they for and on what platforms do they work ?
<13> if i'll call gc() (on Runtime or System) this will guarantee that every discarded objects will be garbage collected ?
<14> no
<14> there is no way to ensure that at all
<13> i saw in the documentation this expresion : "the Java Virtual Machine has made a best effort to reclaim space from all discarded objects"
<13> after call
<14> it makes a best effort anyway
<14> but best effort is far from guarantee
<13> but this not ensure that
<13> ty sabre
<14> you're welcome
<14> whatever the case...it beats the hell out of a language such as C where memory management is complicated and often an issue
<13> this means calling gc in not an improvement
<14> not really
<14> but don't think that the java gc does not do a good job
<14> on the contrary it does an excellent job
<9> testerul: that's correct, telling the system to GC is not wise
<10> it smells of an attempt to fiddle with symptoms.
<9> indeed
<8> what method do i have to call when i add rows to a customtablemodel to refresh the table?
<6> repaint
<6> this question pops up once a day
<8> doesn't function... but when i resize a column then the content is refreshing :(
<8> any other idea?
<6> no sorry, I know nothing of awt/swing
<8> :( anyone else!
<14> try paintComponent()
<14> http://java.sun.com/docs/books/tutorial/uiswing/14painting/problems.html
<14> shouldn't be too long :Z
<8> hmmm
<14> great we finally have machines to migrate to WAS5.1 and JDK1.4 HOLY LORD IT'S A MIRACLE
<6> heh
<6> our Tomcat5 to Tomcat5.5, Jboss3 to Jboss 4 and Java1.4 to 1.5 took no time at all
<8> sabre any idea why it is refreshing only on a column resizing?
<14> i don't think it will be that big of a deal either...just that we are now so ancient
<14> dls-128 no i don't program GUI either
<8> :(
<14> but JTable is a descendent of JComponent no?
<14> and if you look at that link I gave you...what is the first problem it discusses?
<8> i don't really understand the paint and repaint process :(
<14> then READ
<15> what is the diff between enumerator and iterator
<6> differences are huge
<6> read the api docs for both
<15> it says in iterator the elements can be removed while traversing and better names for methods
<15> is there any other things
<6> Enumeration is a legacy interface which does not come under the collection framework, where as Iterator is an interface present in the collection framework.
<15> yes i know that, as you said enumeration is a strange word in oops. thats why it was renamed as iterator which is familiar in oops. enumerator is found in vector, iterator in collection framework.
<15> any other like related to performance
<6> I think a quick google, and you'll find plenty on performance
<6> I just noticed a forum entry at javaranch for example
<6> right off to pub for World Cup, bbl.
<15> thank you, enjoy!
<6> ta ;)
<15> please define multithreading
<16> just that, multiple threads.
<15> how could i answer this question in interview
<16> sathish: by reading up on it so you know what this is all about.
<15> I read a chapter of it in books, i could understand it (not in excellence) but could not find a precise definition what the interviewrs expect
<16> sathish: they expect you to tell them what you know.
<16> so if you don't know you tell them "I don't know".
<10> there is no point telling you what to say in job interviews on basic subjects.
<10> you will come across like a complete idiot if you try to reproduce what you have heard hear or elsewhere.
<17> i guess by the room title i cant ask for any help
<10> get your feed wet, learn the stuff, play with it. that's the real stuff, then you don't need to learn by heart.
<16> not only that; what about this: yay, your cheating got you hired. "Now, please write us a small multi threaded routine to pick up and check new html pages". Then what will you do?
<10> PanMan: it doesn't say "no asking for help in here".
<17> ahh ok
<17> i am trying to make this double shw deciaml places but it keeps losing them when i show it
<17> double resulthrs = value * size * 8 / speed / 36000;
<17> resultBox.setText((Double.toString(resulthrs)) + "hrs ");
<10> no idea what "double shw deciaml" means.
<17> opps sorry bad typing
<17> btw value size and speed are all int's
<17> it keeps rounding down to the whole number
<16> why not check the API docs to see what methods the Double cl*** has available?
<17> i have and couldnt make head or tails of them guess im just jumping ahead of my ability
<16> you're using toString. That ends up as a common String. What about other options?
<16> PanMan: uuuhhh
<17> such as ?
<16> First I'd make sure that you grasp what a Double is. Then check what it extends, then check what methods you have available as a whole.
<17> will do
<16> A quick peek learns me it extends number, which extends object (but thats likely useless). But number.. You can use that to show the Double in another "form" (say; intValue() which returns an int). And then you can use the methods available in Integer.
<16> hmm, lets see.
<16> PanMan: I wonder.. have you ever worked with this stuff before? Meaning; setup integers or other number-like objects/values to show something rounded up ?
