我打算做一个基于Jxta的多人聊天工具
我是这样做的，每个peer都有一个serverSocket监听
如此：JxtaSocket socket = (JxtaSocket) serverSocket.accept();
使用JxtaSocket建立请求，如此：JxtaSocket socket = new JxtaSocket(group,id,adv,5000,true);
其中id是目标peer的peerId，但始终报异常：
java.net.SocketTimeoutException: Connection timeout (connect)

如果将id改为使用null只能自己和自己会话，不能和其他peer会话
