SocketException: Connection reset on server with ObjectInputStream

Question

I\'m trying to get my head around the ObjectInputStream/ObjectOutputStream, so I create a very simple server-client application where the client sends a HashMap object

Answer 1

This happen because the client socket is automatically terminated after that all its code is executed.

For example, if you add

while (true) {
    System.out.println("no operation");
    try {
        Thread.sleep(10000);
    } catch(InterruptedException e) {
        e.printStackTrace();
    }
}

at the end of your client code, you don't get any Connection Reset, because your client socket will never be terminated.

So, the client side socket is closed and the server side socket has to handle this exception. You should just go out from the loop when you get this exception, so:

boolean connected = true;
while (connected) {
    try {
        //your code
    } catch (SocketException e) {
        connected = false;
    }
}
