Java HotSpot Virtual Machine

Hi, I'm trying to create simple Client/Server Apps in which the Client sends the JButton that was clicked to the server and the server outputs to its JTextField and to the Serial Port, but i keep getting a JVM_Bind error, so i know im not closing the ports right... one other thing, in the command line i have to type >javaw servername.java TWICE in order for it to go, i seriously think the problem is with me not closing the ports right.
Thanks

CLIENT
