Make two Java applications in the same LAN aware of each other

Question

I have a Java program running on two computers that are on the same network. I would like these applications to recognize each other, so they could communicate directly, and not communicate with the server to send messages.

I believe that I may have a solution to how this will work, but I can not find examples to compare my solution. Do you guys know how this problem is usually solved?
