- Java persistenceHi group,
i'm looking for a Java persistence framework that is able to cope with
changes of the class source, i.e. new/changed attributes and/or
methods. Say you have an exported (persistent) instance of a old class
version and want to reload it into a newly started program that uses a
new version of the class. Is there some framework that can do the job
or do i have a strange idea of what instance persistence realy is?
Thanks, Frank.

- importing and using .class fileI have a .class file, not a .java file.
After I imported it to my Eclipse Project,
I had no idea to use it.
I put
import foo;
but eclipse doesn't recognize 'foo' as a class name.
How can I use a .class file?
Do I need its source file?

- help with eventListenershi
I was just wonder if some one could tell me how i do this...
You press a button and if the check box is selected it does something and if
it isn't nothing happens.
I know how do the, if a button is pressed something happens, but I'm stuck
with how to check what the check box status is. I'm pretty sure you have to
use an ItemListener but i don't understand it when you have to use an
actionListener aswell. Please help. Even tell me where abouts to look for
the answer would be a great help.
thanks

- question about jnlp (java web start)Hi,
I created a jnlp file, a jar file and a html on my local disk.
Clicking the link of jnlp from the webpage, my Java Web Start
launches.
Everything is ok.
But after I've uploaded all the files to the webserver, my browsers
(Mozilla and IE) everytime just read and display the plain text in
jnlp file. The Web Start never launches. (The permission for all the
files is 755.)
Anyone know why?
Thanks a lot !!!

- using the debuggerHi,
I've got a loop which is going through an array, and I'm getting an
array index out of bounds exception. Usually to find this sort of
error I'd use System.out.println() or look at the code until the penny
drops, but I think it must be quicker to use the debugger. I want to
see the local variables in the loop, so I recompiled the class with
the loop, and the main class. The debugger says to recompile with -g
so I did:
javac -g TheMainClass.java, and javac -g TheLoopClass.java.
Then when I run the program and the debugger stops at the exception,
I type locals and the debugger still says recompile with -g.
Does that mean I need to recompile every class the program is using?
Also, is there any tutorial or instructions for using the debugger?
Documentation for any standard debugger would probably explain some of
the general priciples I need to know.
Thanks for any help,
Gerard

first explain how your super contrived hello world example has any
RELEVANCE what so ever to Apache, Jakarta or anything thing else server
related?
If you are not a troll, then your least worry is the speed of running a
contrived hello world example, it is more like getting much more basic
fundemental understanding about practical programming.
if you are just trolling just stop.

- video/audio transfer. Java vs .NETI know I'm a little crazy to ask it in a Java discussion group, but I
just would like to know about Java and .NET possibilities to handle
images and videos. I know Java has JMF and other interesting stuff to
do that, besides of thousands of classes in the web.
But, have you ever tried to handle video in .NET? In what points in
Java better/worse than it?
Thank you very much... bye!

- netbean5 packaging travailHello
I have a project, an applet, that compiles and runs
fine with some 3rd party jars that are in the
libraries folder. It never packages them into the
final project jar. I fixed this problem for the
swing-layout with:
<jar update="true" destfile="${dist.jar}">
<zipfileset
src="${libs.swing-layout.classpath}"/>
<!-- <zipfileset
src="${libs.3rdparty.classpath}"/> -->
</jar>
unaware of the nameing convention and of course I dont
know how to get it to work with anything else. Can
someone instruct what is necessary in config or
build.xml to get the 3rd party jars packaged? tia.

- switch to editor when renderer gets focusI have a jcombobox as an editor inside a jtable.
I would like to switch to the editor as soon as they enter the column
with the jcombobox in it so they can start editing right away.
This is an editable jcombobox, so when tabbing through the columns in
the jtable, the first key stroke only activates the editor -- so the
second keystroke is being used instead of the first.
entering the column with the jcombobox in it, you have to hit the space
bar or the enter key before you can type in the jcombobox editor.
Otherwise, if you start typing "Smith" in the column, the "S" activates
the combobox editor and the list jumps to the "m" section instead of
the "s" section.
Appreciate the help. TIA

- dynamically change the classpathI've got a question regarding how to "dynamically change
the classpath" ?
I've already written some (simple) custom ClassLoaders,
to help... loading classes.
This time, I need to do something and I think I need to
use a custom ClassLoader but I'm really not sure. And
if I need to use/write one, I don't know of to go about
it.
Here's my problem:
- I've got several .jars that my application needs and I
have to keep these files as separated jars.
- I cannot be sure of the exact location of these jars, so
I cannot add them to the main jar's MANIFEST.MF's Class-Path:.
- At runtime, I will have a way to know where those jars are
located.
How can I tell the application "if you don't find a class, go
look into those jars"?
I've read several articles/webpages and read code sample, but
I don't get it.
I know how to load a certain class from a .jar, but not how
to tell the application "if you don't find a class then look
into xxx.jar and yyy.jar and zzz.jar before throwing a
ClassDefNotFoundError".
On Roedy's site, it is written:
> Why would you ever want a custom ClassLoader?
>
> ...
> They let you dynamically change the classpath.
> ...
So I think I need to use a custom ClassLoader (an URLClassLoader?),
but how...
Thanks in advance for any help,
Jean

- Ant : how can I use properties to store nested elementHi all,
I have a build script which uses <fileset> nested in <path> to store
the classpath and then this <path> is used in javac. e.g.
<path id="MY_CLASSPATH">
<fileset dir="${build.dir.lib}" includes="**/*.*"/>
<fileset file="${global.lib.j2ee}"/>
</path>
<javac
srcdir = "${project.compile.src}"
destdir = "${project.compile.dest}">
<classpath>
<path refid="MY_CLASSPATH"/>
</classpath>
</javac>
I just wondering is it possible to store the fileset in the properties
file so that I can reference it in other place? I want to do a fileset
instead of writing all the jar file names explicitly.
e.g.
In the properties file:
project.compile.classpath=dir:${build.dir.lib}:file:${global.lib.j2ee}
(or something like that....)
then in my build.xml:
<javac
srcdir = "${project.compile.src}"
destdir = "${project.compile.dest}">
classpath = "${project.compile.classpath}">
</javac>

excelss.xsd. The first one passes OK, but doesn't contain Worksheet
element, which is the root element for Excel 2003 documents saved as
XML. The other schema, excelss.xsd, contains the definition of this
element, but doesn't pass through JAXB. The output of:

- Strange JFrame / JPanel behaviourDear friends,
I have a problem with a JFrame (NewJFrame) and a JPanel (JP) subclass.
NewJFrame acts as a container for JP. Now, let's suppose that "a" is a
JP instance variable, with public modifier, to put it simple.
So, if I want to modify "a" from NewJFrame, and JP is a NewJframe's
instance variable, it can be done as follows:
jp.a = 8; // for instance
so far so good.
But, I've found a strange behaviour: when I try to print "a" from JP's
paintComponent() (overloaded), its value remains unchanged.
Here is the code, edited with Netbeans:
// ===================================================================
/**
*
* "container" JFrame
*/
public class NewJFrame extends javax.swing.JFrame {
private javax.swing.JMenu jMenu1;
private javax.swing.JMenu jMenu2;
private javax.swing.JMenuBar jMenuBar1;
private javax.swing.JMenuBar jMenuBar2;
private javax.swing.JMenuItem jMenuItem1;
private JP j = new JP();
public NewJFrame() {
initComponents();
}
private void initComponents() {
jMenuBar1 = new javax.swing.JMenuBar();
jMenu1 = new javax.swing.JMenu();
jMenuBar2 = new javax.swing.JMenuBar();
jMenu2 = new javax.swing.JMenu();
jMenuItem1 = new javax.swing.JMenuItem();
jMenu1.setText("Menu");
jMenuBar1.add(jMenu1);
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
jMenu2.setText("Menu");
jMenuItem1.setText("Item");
jMenuItem1.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
jMenuItem1ActionPerformed(evt);
}
});
jMenu2.add(jMenuItem1);
jMenuBar2.add(jMenu2);
setJMenuBar(jMenuBar2);
pack();
}
// </editor-fold>
// modify "a" from NewJFrame
private void jMenuItem1ActionPerformed(java.awt.event.ActionEvent evt) {
j.a++;
System.out.println("a: "+ j.a);
j.repaint();
System.out.println("a: "+ j.a);
}
public void init2(){
JP j = new JP();
getContentPane().add(j, java.awt.BorderLayout.CENTER);
pack();
}
public static void main(String args[]) {
NewJFrame n = new NewJFrame();
n.init2();
n.setVisible(true);
System.out.println(n.j);
n.j.a = 3;
System.out.println(n.j.a);
}
}
// "extended" JPanel
import java.awt.Graphics;
import javax.swing.JPanel;
/**
*
* extended JPanel
*/
public class JP extends JPanel{
public int a =0;
/** Creates a new instance of JP */
public JP() {
}
public void paintComponent(Graphics g){
System.out.println(this.a);
// [snip]
}
}
=========================================================================
In "jMenuItem1ActionPerformed", (using a JMenu) I tried to
- increment a
- print a (apparently incremented)
- invoke JS repaint, which prints a, again, but NOT incremented... why?
- reprint a: now it says it's incremented!!!
every time I call paintComponent (for example, resizing the component),
it says that a is "its" a.
It seems like paintComponent maintains its own copy of a, with the
unchanged value, or that paintComponent doesn't see any update to a...
Is it a mistake (I hope) or a bug?
Any help would be appreciated.

- Java Window/GUI HelpOk im trying to create a program in java right now and my knowledge of
it has proved somewhat .... limited.....
Info:
Im making a program using javaspaces to simulate an auction over the
network.
Requirements:
1) user can add a lot to the auction
2) browse current lots on sale
3) users can withdraw their item from sale.
OK now this has to be done as a GUI which is what is hindering me.
The only type of GUI work i have done have been fairly static.
Just a plain window with a few buttons and such which might bring up a
picture or change some text in a text box or something.
But what im having trouble with now is the whole GUI design and how to
go about it.
Say i had 3 butons in my window |Add| |Browse| |withdraw|.
Clicking any of these should change the whole structure of the window
and i dont know how to do this..
Itd be a case of clearing half of the window off and redrawing over
the top of it.
Unless i went the route of having an extremely simple window with 3
buttons, clicking each would open up a new window with the desired
options...
What would be the best way to go about it? and how would i go about
implementing it? just a few tips are needed :)
Im really not a windows fan... a console app would take an hour or so.
This is gonna keep me going for aaaaaages :$
I hope im making sense and not babbing too much - 36 hours without
sleep and a huge abundance of caffeine is warping my mind o.O

- negative dns caching problem *resolved* (was Re: JDK 1.5.0 patchsetAfter months of fighting with this, today I stumbled upon the answer. It
was a java command line test case that led me to it.
>From the command line, FreeBSD's JDK does -exactly- what it is supposed to
with negative caching. My test case involved restarting BIND, adding a
firewall rule for a host's name servers, having Java try to resolve the
name (and of course fail), having Java wait while removing the firewall
rule and having Java try again to resolve the name. All the while I was
watching network traffic with tcpdump.
Exactly as it is supposed to, the JDK tried again and succeeded after I
removed the firewall rule.
So this meant that it had to be something to do with Tomcat or
commons-daemon/jsvc.
On a whim, I removed the entry for Tomcat's native libraries, and it
started to work correctly.
Then I did an ldd against libtcnative, and found that I had compiled it
with gcc 4.2.1. Knowing that there are problems with gcc 4.2, I
recompiled with gcc 3.4.6. It continues to work correctly.
So this turned out to be a multi-pronged problem. Earlier I was building
a version of the JDK that somehow never read java.security, and that
required wiping out the work directory entirely and bootstrapping off the
Diablo JDK. Then, something about compiling the Tomcat native libraries
with gcc 4.2.1 was apparently creating this bad behaviour situation.
So if you're using Tomcat, and you want to use the Tomcat native
libraries, do not compile them with gcc 4.2. In fact, you probably will
want to make sure you compile them with the same major.minor version of
gcc you used to compile libapr just to be safe. The Tomcat native library
IS capable of screwing your DNS resolution.

- need Java book for a C# / C C++ proficient programmer?hi,
I've never cared for Java before but now i feel like learning it. I'm
an MCP and a pretty experienced programmer. Also, i plan to take the
SCJP and maybe the SCMAD exams.
Is there a java book out that is for a programmer?? I already have a
copy of Hebert S. java reference, that would be my last option. Also,
i would want the books to somewhat cover the exams I plan to do.
Thanks so much

- Printing questionsHello!
I'm trying to develop an application to print PDF files, using JPedal.
Two questions:
1) I'd like users can specify printing properties, like size,
margins... following an example on JPedal site I tryed:
// new attribute set
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
// dialog
printJob.printDialog(aset);
// read dialog properties
PageRanges r = (PageRanges)aset.get(PageRanges.class);
PageFormat pf = (PageFormat)aset.get(PageFormat.class);
but it doesn't work... :(
Is there a way to set those parameters via code? I need to set margins
to 0,0,0,0...
2) I'd like to improve the quality of printed docs... I think it uses
a very low quality to render my PDF (like 72dpi or so), is there a way
to increase dpi? In a PDFProducer for TFax I was able to do that
passing a bigger BufferedImage to Jpedal, is there a way to do the
same thing here (without redifining the print() method)?
Thanks!

- How to identify the cause of ClassCastException?Hi,
I have two classes: State and WarmState.
public class State
{
... //many fields
}
public class WarmState extends State
{
... //more fields
}
Now, I have a State reference state, whose corresponding object was
created and filled. I believe/guess/thought it is a WarmState object.
Now I need to pass state to a method which only take WarmState
parameter. So I cast state to WarmState type. But I ran into
ClassCastException. Like I said, state was created and loaded from a xml
file. I hope to find out what caused ClassCastException. But neither of
these gave me a clue:
e.getMessage()
e.getLocalMessage()
e.printStackTrace()
Thank you for your help.

- Newbie Question: Eclipse RCP - three questionsHi all,
I'm trying to develop Eclipse RCP database based application and I've faced
following problems.
First :
I don't know where can I create and dispose the ImageRegistry ?
Class WorkbenchAdvisor doesn't seem to be right place to do this, I couldn't
find the method
like initializeImageRegistry.
Second:
Where should I keep for example the database connections or references to
the beans
shared among different parts of the application especially further plugins ?
Third:
Is there any example of the real database driven RCP application with source
code available
or at least an article describing this topic ?
Thank's in advance
