[vtkusers] Java Data streaming query

If you look at vtkSocketCommunicator, and more specifically the examples 
SocketServer.cxx and SocketClient.cxx this should give you an idea about 
how you can send vtkDataObject's over a socket.  It would look something 
like:

Server side: 

  if(!comm->Send(myPolyData, 1, 9)) {
    // error sending data, handle appropriately
  }

Client side:

  if(!comm->Receive(myPolyData, 1, 9)) {
    // we didn't receive the data
  }
  
regards,
