    Unhappy Socket Listening problem in Netbeans

    i am making peer to peer chat application. the following code can successfully send messages to next client application but could not receive the messages from the client. the code is written in Netbeans.

    the listening code is commented at the moment because the code goes stuck on that area. can anybody solve this problem or suggest me how to solve this issue. I am a new user of Netbean. i think listening code correct because it is working somewhere else but i think code placement is not correct. so can anybody please solve or suggest me this issue, I really need to solve it urgently. Thank you.
