[OMPI users] Package mpi does not exist

[Ibrahim Ikhlawi]

Hi,

I am beginner in OpenMPI. I want to run some examples from the extracted 
openmpi-1.10.0/example,
namely Hello.java and Ring.java.
But when I compile Hello.java with: 
javac Hello.java

I get this error:

Hello.java:25: error: package mpi does not exist
import mpi.*;
^
Hello.java:28: error: cannot find symbol
    static public void main(String[] args) throws MPIException {
                                                  ^
  symbol:   class MPIException
  location: class Hello
Hello.java:31: error: cannot find symbol
    MPI.Init(args);
    ^
  symbol:   variable MPI
  location: class Hello
Hello.java:33: error: package MPI does not exist
    int myrank = MPI.COMM_WORLD.getRank();
                    ^
Hello.java:34: error: package MPI does not exist
    int size = MPI.COMM_WORLD.getSize() ;
                  ^
Hello.java:37: error: cannot find symbol
    MPI.Finalize();
    ^
  symbol:   variable MPI
  location: class Hello
6 errors
How can I resolve this problem or where can I find the mpi.jar?

Best regards,
Ibrahim

PS: I cannot find mpi.jar in /lib directory.
