This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
As Lasse stated in your previous post, you can use either JNI or Runtime.exec() to perform system calls. While we'd love to help you with any problems you have, we won't do your homework for you. Your best bet is to buckle down, follow the links Lasse provided, read the docs and tutorial, write some code and come back with some more specific questions than "please help me to do this work".
