If your SUN is already running CDE, for start try a
# xhost +
If your not running CDE, following the according threads in these forums, search in google, etc..

Its not a SUN problem ((
Its a classpath problem.

I had the same problem.

It turned out that my server wasn't running a X server.
I fact the NoClassDefFound exception is throwed because the class
tries to initialize awt related objects statically.
Since these object can't be initialized, the corresponding class can't be loaded.

A nice solution is to use Xvfb, if you don't want to run a X server.
Don't forget to set the DISPLAY environment variable.
