I don't know how you use MPI.OBJECT, but I have ported some small programs, which used MPI.OBJECT to the new interface with structures. You can compile and run a program with the following commands: mpijavac -d $HOME/mpi_classfiles BcastStructArrayMain.java mpiexec -np 3 java -cp $HOME/mpi_classfiles BcastStructArrayMain Perhaps you get an idea how you can port your MPI.OBJECT programs, when you look at my small example programs. Kind regards Siegmar
