How can i make java program executable?

[Viro]

I think the reason why it only works in the Terminal, is because the files /etc/profile and $HOME/.profile (or $HOME/.bash_profile) are only read when you run the Terminal. It's a strange 'feature' (I'd call it a bug) of Debian and Ubuntu.

Assuming you are using GNOME, try adding the PATH definitions to your JDK to the file .gnomerc in your home directory. It is the same format at .bashrc/.profile/and gang. Log out and log in again. That should make your shell script work from inside GNOME without the need for opening a terminal.

No, they're not. They ought to be persisted into the X environment, at least they are for KDM. If GDM got broken again...

If that script is exactly as written, what does ~/.xsession-errors say when you try to run it? What does this application do?

[Viro]

Well, they weren't for GNOME for a long time, and I remember on the Debian mailing lists about a year ago where the developers just recommended adding the definitions to .gnomerc while they sorted things out. Haven't heard of them sorting this out, and IIRC I added my definitions to /etc/profile and nothing happened, so I'm guessing things haven't changed .

If you make a launcher on the panel or the desktop or whatever, there's an option to 'run in terminal'. That should allow you to still have a launcher, it'll just open up a terminal as well to run the program.

[jerome bettis]

i think the file you're looking for is /etc/gdm/gdm.conf ... have a look in there for the path, add /home/you/bin at the end and try that.

Under Behavior, make sure "Run executable text files when they are clicked" is selected.

Also check to make sure the file extension is the proper one for that format (I should have qouted so I'd remember if you said or not), and that its associated correctly in nautilus...

Just a guess, but hope it helps..

I have already tried that one mate, it opens up a terminal but disappears after one second and still no program is running.

Nothing is happening when i double clicked it.

Ok, this is what i have on my ~/.xsession-errors when i tried to run my simple test program "Hello World" inside the JOptionPane.showMessageDialog(). I have highlighted the part where i think errors that generated by java.

Do you think there is something missing with the installation of my java?
This is how i setup java on my system (this might help):
* I downloaded the jdk1.5.0_06 from the Sun's website.
* Created directory for my java called /java on /usr and
that's where i installed it.
* Then i added export PATH=/usr/java/jdk1.5.0_06/bin/:$PATH to my ~/.bashrc to set its classpath.

Cheers mate...

Couldn't find .gnomerc in my home directory. Thanks.
