Re: [Java-gnome-developer] how to specify classpath

[Andrew C. <an...@op...>]

I assume you had a look at the README file that comes with java-gnome.
It has further examples of running code:
http://java-gnome.sourceforge.net/4.0/README.html#using
but the problem you're having is fairly simple to address.

Although Java searches paths for hierarchies of .class files, it does
not load .jar files. You have to specify them by name. 

$ cd doc/examples/
$ javac -classpath /usr/share/java/gtk-4.0.jar button/ExamplePressMe.java

And to run it,

$ java -client -ea -classpath /usr/share/java/gtk-4.0.jar:. button.ExamplePressMe

[You may need to add -Djava.library.path=/usr/lib/jni on Debian; I'm
not sure if that's on the default system linker search path]

Yes, this is all a bit verbose, but unfortunately that's the way Java
is.

Or you could do it all from another location:

$ javac -classpath /usr/share/java/gtk-4.0.jar -d /tmp/examples /path/to/java-gnome/doc/examples/button/ExamplePressMe.java
$ java -client -ea -classpath /usr/share/java/gtk-4.0.jar:/tmp/examples -Djava.library.path=/usr/lib/jni button.ExamplePressMe

Hopefully you see the pattern now.

If you were build java-gnome from source yourself, you would find that
`make test` also builds the example code (and puts the resulting .class
files in tmp/tests/). so,

$ java -client -ea -classpath tmp/gtk-4.0.jar:tmp/tests/ -Djava.library.path=tmp button.ExamplePressMe

would run it for you.

Good luck,
