ConnectException?

[chyrl]

Strange, I never know how to resolve this.
I have created a server, in which accepts multi-clients, and client using MVC.
I have threaded some parts of the sockets.
Yet, I recieve this error.

java.net.ConnectException: Connection refused: connect
        at java.net.PlainSocketImpl.socketConnect(Native Method)
        at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333)
        at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:195)
        at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:182)
        at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366)
        at java.net.Socket.connect(Socket.java:519)
        at java.net.Socket.connect(Socket.java:469)
        at java.net.Socket.<init>(Socket.java:366)
        at java.net.Socket.<init>(Socket.java:209)
...

This exception always pertains to this part of the client

socket = new Socket(InetAddress.getByName(serverIPAdd), portNumber);

And here's the Server Model

Looks like you're behind a firewall or something of that sort. A refused connection means it was successful in finding the destination, but the destination is saying that it isn't going to allow that connection. Are you running a nix/windows FW? Try disabling all of them (if running more than one anyway) and see what happens.
