Hi,

Please have a look at the following two set of code, the server code and the client code

UserRegistrationServer.java



UserRegisterClient.java



In here, it is throwing an exception "java.net.SocketException: Software caused connection abort: recv failed" after the first data entry attempt, which means from the second data entry onwards. I have no idea why this is. This exception is caught in the client application. Please help me. Thanks.

The server closes the connection after sending its response.

Your protocol is not working. Your server accepts a new connection, reads from it, writes to it, then closes it. Your client creates a new connection, writes to it, reads from it, and then expects it to remain open.

I see two options:
1) in the server, keep the connection open. You will need a new thread that keeps reading from and writing to the connection, or you will block new connections.
2) in the client, don't store the socket and the streams globally, but reconnect and recreate the streams when pressing the button only.

Glancing over this code I see two possible corrections:
1) In UserRegisterClient, close the connection after you're done with it.
2) In UserRegistrationConnection, don't start the thread if an exception occurs. Move line 40 to after line 25.
