The problem here is that the Java-GNOME libraries are not in your
classpath.  You need to add the gtk and gnome jar files to your classpath
in order to compile this example.

There is a simple solution for this issue as well.  The example
cannot find the Java-GNOME shared objects to load them
at runtime.  You can resolve this by either adding the path
to the shared objects to your LD_LIBRARY_PATH env variable
or you can specify -Djava.library.path=/usr/lib/jni as a VM
argument.  This VM argument is set up in the run dialog of eclipse
by selecting the Arguments tab.
