You need to check if the environment variable JAVA_HOME is set correctly and 
there was one nasty trick that jhandles expect a client folder instead of a 
server folder in the java installation at the right place.

It is in the folder /usr/lib64/jvm/jre/lib/amd64 on opensuse 64 bit.
Just make a symbolic link named client in that folder (but check before the 
folder can be different on ubuntu) which points to server.

If it tells you that it cannot find jogl make sure yiu have jogl installed.

I hope there was nothing else which I forgot now.
