Ralph - I'm relying on you guys to support Java, hope it makes it back in soon !!!
I've had no problems, by the way.
Karos - Were you able to make and run the Java examples in the MPI_ROOT/examples directory ?
I started with those after similar hiccups trying to get things up and running.

Subject: Re: [OMPI users] Problem with mpirun for java codes
Just as an FYI: we have removed the Java bindings from the 1.7.0 release due to all the reported errors - looks like that code just isn't ready yet for release. It remains available on the nightly snapshots of the developer's trunk while we continue to debug it.
With that said, I tried your example using the current developer's trunk - and it worked just fine.
I ran it on a single node, however. Were you running this across multiple nodes? Is it possible that the "classes" directory wasn't available on the remote node?
