Redirecting output to Lego ev3 robot

I am playing with the Lego Mindstorm's ev3 robots.
The robot itself is running some kind of Linux and can run java programs out of the box. I copy the jar file with scp, then with ssh I send the command jrun -cp .... to start the jar file. When it runs I get the output of the java application in the terminal on the remote host, where I have send the command.
Can I get the output from jrun on the ev3?
There is some Eclipse plugin for that, but I'd like to do it myself. This would mean, that I somehow need to redirect the output from the console on the remote machine to the remote host, but not really sure how this is supposed to work. My follow-up question would be, can I simultaneously get the same output on the display of the ev3 and on the my computer, where I am sending the command.
