  1. I'm creating an application where client connects to server, retrieves some data and after that connection is closed.

  2. He spends some time changing that data and then connects again to the server sends it back and connection is closed.

  3. At server data is compared with original and saved to database if it validates.

I see only one solution to this - creating two ServerSocket one for input and one for output. But it does not seem good solution. Is this the way to do it or is there something else? How can I determine purpose of connection?

PS I'm using JAVA 8.
