Java中同一Web应用程序的两个会话之间的通信

Question

I have a problem like two clients should be accessing my web application. My first question is how can i know that two clients exist.

If two clients exist i should have a communication as mentioned below.

Client1 should write once client1 writes then client2 should read it and will respond once client2 writes then client1 should read it and will respond in this pattern my communication should happen.

Any help will be appreciated...Thanks in advance

Answer 1

Create an HttpSessionListener which will maintain a set of active sessions. When a servlet gets a request from client1 save request body in a client1 session attribute then look for client2 session in active session set, if found take body (previous client2 request) from there and send it as a response to client1.
