Many thanks. I have now built it from source.  I still got the Null Pointer exception with the old code snippet. I changed the code snippet as per your recent post.

Now I got a class path issue

For some reason when I build with target  build-engine

this file jME3-jogl.jar is not copied to this folder

jmonkeyengine-read-only/engine/dist/lib -- all other jar's get copied.

After fixing the above,  Eclipse kept on complaining about gluegen-rt.jar even though it was present in the class path. I moved it to the top of the class path and Eclipse was happy.

Now I am getting this error - looks like some native library is missing. Could you please point me to it.
