[SOLVED] Problem with Java in Eclipse

[Fixel]

Hi, I've used Eclipse previously on another computer and it's worked fine. But on a fresh install it's not working properly.

To test Eclipse I wrote this hello:

import javax.swing.*;
public class program {
public static void main(String[] arg){
JOptionPane.showMessageDialog(null, "I R Test");
System.exit(0);
}
}


Nothing fancy just to see if it all worked properly. It launches and the message shows. But I can't press [OK] or the X, so I have to force-quit it.

I get these "errors" in my console:

So I thought it had something to do with compiz/emerald so I tried switching to Metacity/GKT using the fusion-icon. But it still gives me the same errors.

What should I do? I'm pretty lost.

Considering the weirdness with a bunch of GTK errors, I think the issue lies with your JRE (which I guess is the GNU implementation). You probably can 'fix' it by installing a proper JDK/JRE combo from Sun's; install it like so:


$ sudo aptitude install sun-java6-jdk

(The $ sign is the prompt.)

Then go to your Eclipse, and make the following changes IIRC:

Window -> Preferences -> Java -> Compiler -> Add JRE;
from the window that pops up:

browse to your /usr/lib/jvm/java-[version_number_here]/jre folder;
select that, you should (soon) see a list of standard libs listed in the appropiate section of the pop-up window.

Apply/OK the changes, click on the checkbox before the new compiler entry in the underlying window pane (this sets the new Java as the default compiler) and try a new project.

Thanks! Worked like a charm!
