Subject: Re: [OMPI users] Problem with mpirun for java codes

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.

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?

I get very strange errors. everything is fine when I run OpenMPI for C codes, but when I try to run a simple java code I get very strange error. The code is as simple as the following and I can not get it running: >>> >>>import mpi.*; >>> >>>class JavaMPI { >>>  public static void main(String[] args) throws MPIException { >>>    MPI.Init(args); >>>    System.out.println("Hello world from rank " + >>>      MPI.COMM_WORLD.Rank() + " of " + >>>      MPI.COMM_WORLD.Size() ); >>>    MPI.Finalize(); >>>  } >>>} >>> >>>everything is ok with mpijavac, my java code, etc. when I try to run the code with the following command: >>> >>>/usr/local/bin/mpijavac -d classes JavaMPI.java       --> FINE >>>/usr/local/bin/mpirun -np 2 java -cp ./classes JavaMPI  --> *ERROR* >>> >>>I'll the following error.
