无法从Java绑定到Flex Serversocket

    public function ConnectionManager(address:String, port:Number)
    {
        var server:ServerSocket = new ServerSocket(); 
        try{
            server.addEventListener(Event.CONNECT, onConnect); 
            server.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onSecError);
            server.bind(port);
            server.listen();
        }

public class TCPConnection {

/** Debug Tag */
private static final String TAG = TCPConnection.class.getName();

private Socket socket;
private int port;
private String host;

public TCPConnection(String host, int port) {
    this.port = port;
    this.host = host;
    this.connect();
}

private void connect() {
    System.out.println(\"Trying to establish socket at \"+host+\":\"+port);

    try {
        this.socket = new Socket(host, port);
    } catch (Exception e) {
        e.printStackTrace();
    }
}
