I don't think so, just uninformed. ;-)

Here is your first problem.  When adding .jar files to your classpath, you
must specify each file individually, like this:

/usr/share/java/gtk2.4.jar:/usr/share/java/gnome.jar:...etc.

Putting just /usr/share/java won't work.  Fix this and you'll fix the
majority of your problems.

This one is more tricky to figure out, but easy to fix.  In Eclipse, open
up the Run... dialog and click on the Environment tab.  Click the New
button to add a new environment variable:

Name: LD_LIBRARY_PATH
Value: /usr/lib/jni

That should do it.  Write back if you have more problems.
