Hello Claudio, mpirun should be combining your java.library.path option with the one needed to add the Open MPI's java bindings as well.
Which version of Open MPI are you using? Could you first try to compile the Ring.java code in ompi/examples and run it with the following additional mpirun parameter? mpirun -np 1 --mca odls_base_verbose 100 java Ring then try your application with the same "odls_base_verbose" mpirun option and post the output from the two runs to the mail list? I suspect there may be a bug with building the combined java.library.path in the Open MPI code.
