Boris,
You were correct. The biggest problem was part 2 setting up for reading an output
stream from Orion. Once I told Orion I wished to do input also "setDoInput( true )" and
requested the input stream "conn.getInputStream()" everything worked like it should. I
also changed the println to print.
Thanks for your help.
