Something to know about socket and multithreading in java

Question

I want to send a message to a socket on a gateway(client), and then wait for a message to recieve from a gateway.

While waiting, on other hand I again send a message from server socket to gateway which is client but on accept() (ServerSocket) method my connection blocks.

I was wondering is this because of the previous request which was waiting to recieve something by using inputStream . I used threads to maintain this and use setReuseAddress() to do this.

I am not posting a code right now as I just want to know is this logic is fine or is there any logic to handle multiple requests(messages) to be send from a Server-Socket to a client-Socket and I also dont want to close the socket because the socket has to be connected through out the application.

Answer 1

On the client end, you use a Socket object to connect to a server which uses a single ServerSocket . Once the connection is established you will have a Socket at both ends and you can use this Socket to Serversocket connection to send data in either direction. ie A single server socket is needed for new connections only.
