how to detect whether any socket connected with any url in system, java

Question

Hi I am facing a problem. I want to detect whether socket connection with a particular ip address is already established in the system. In linux there are 4 desktops so if tcp socket connection is already established in 2nd desktop and I want to re-establish in third desktop or if I want to re-establish another connection using another user with the same ip address then I should receive error message.

How to get this functionality through java program

You could run netstat -a and parse the output.
