i am getting this exception : Address already in use : JVM_Bind
how do you unbind?
how do you close a socket connection?

Some other program altogether -- or a previously executed copy of the same program -- may already be running, bound to that same port. What port are you trying to listen on?

There is already some application running at that port.many times even if you close the application the jvm keeps on that case you can use the program manager of your app;ication for checking and killing any unnecessay program that might be using that port..some of the program make thread that make use of the port and if the threads are not demon then they would continue to run even after the main in that case it still migh be using the kill that application that is using the port and then again start the server...
