Hi,
I've just installed libjava-gnome-java on a Ubuntu 13.04 box (only Linux
dist I've got available). Fired up Eclipse Juno, added the library to my
project (and the docs of course) and tried to run it but I'm getting an
exception! What is going on here?
The program is this:
package uk.org.linuxgrotto.ui;
import org.apache.log4j.Logger;
import org.gnome.gtk.Gtk;
/**
* The class instantiates the main window.
*
* @author jgroth
*
*/
public class DesktopFileCreator {
private static Logger log = Logger.getLogger(DesktopFileCreator.class);
public static void main(String[] args) {
Gtk.init(args);
}
}
Exception in thread "main" java.lang.ExceptionInInitializerError
at org.gnome.gtk.Gtk.init(Gtk.java:95)
at
uk.org.linuxgrotto.ui.DesktopFileCreator.main(DesktopFileCreator.java:63)
Caused by: java.lang.NullPointerException
at org.freedesktop.bindings.Plumbing.loadNativeCode(Plumbing.java:192)
at org.freedesktop.bindings.Plumbing.<clinit>(Plumbing.java:110)
... 2 more
This is so minimal it can't be any smaller and yet an exception.
Regards,
Johan

This means the code at line 191 returned null. [which is why I'm so particular about not chaining method calls]. So ProtectionDomain's getCodeSource() is returning null. That's annoying; . It doesn't here. What version of Java are you using? And, can you describe how you're running the program (from within Eclipse? from the command line?). AfC Sydney |

It seems to me that java-gnome 4.1.2 is broken on Ubuntu 13.04. I simply can't get it to work. Oh, well, back to using Swing. Regards, Johan |

Please feel free to do what ever makes you happy, but keep in mind that many of the other people else using java-gnome are using it on Ubuntu. It works fine for them, so it's possible that something about your environment is different. Personally, I'd like to find out what that is, because it's entirely possible that other people will encounter the same problem. But since *I* can't see the problem, I need your help.

It's fairly easy - just open a terminal and give: *sudo add-apt-repository ppa:java-gnome/ppa* *sudo apt-get update* *sudo apt-get install java-gnome* The first command adds the PPA to your software sources. The second one updates the package index of your system. The third one actually installs the software.

I do use/have used java gnome on all 3 versions of Ubuntu starting from Ubuntu 12.04 namely 12.04, 12.10, 13.04. It does work fine on all of these versions. Only difference I can think of is our jar file is built locally and deployed to internal maven repository where all other developers access it. If I remember correctly, the jar is built on 12.04 and used on all other versions of ubuntu. We do use Oracle JDK.

Mind you, I've tried openjdk 6 with no difference. Could it be I'm on a 64 bit version of Linux? Regards, Johan |

Sorry for the late reply. We use both 32bit and 64bit though we are in process of migrating to 64bit completely. Not that it should make any difference, but the code runs on standalone boxes and diverse virtual host. You may want to look at dependencies on 13.04. If I remember correctly we had some minor trouble getting it work on 13.04 because of libwebp2 not easily available on 13.04 You might have already taken care of it, but can you confirm its really using oracle jdk? I have bean burned couple of times on ubntu because default points openjdk and even after setting java home it was still picking up oracle jdk. Proper fix turned out to be update-altenatives and point /usr/bin/java to oracle java. Things do fail mysteriously on openjdk, at least in my observation. Since I use openjdk only accidentally never investigated why/where etc. Regards, Niranjan On 07/24/2013 12:49 AM, Johan Groth wrote: > On 23/07/2013 20:31, Niranjan Rao wrote: >> I do use/have used java gnome on all 3 versions of Ubuntu starting from >> Ubuntu 12.04 namely 12.04, 12.10, 13.04.
