java version “1.7.0_65”
smack 4.0.0
The test code:
final ConnectionConfiguration connectionConfig = new ConnectionConfiguration( "127.0.0.1", Integer.parseInt("5222"), "yuyong.com");
connectionConfig.setReconnectionAllowed(true);
connectionConfig.setSendPresence(true);
XMPPConnection connection = new XMPPTCPConnection(connectionConfig);
System.out.println(connection.isAuthenticated());
try {
connection.connect();
connection.login("ht", "890806");
Chat chat = ChatManager.getInstanceFor(connection).createChat("admin@yuyong.com", new MessageListener() {
public void processMessage(Chat chat, Message message) {
// Print out any messages we get back to standard out.
System.out.println("Received message: " + message);
}
});
chat.sendMessage("Howdy!");
} catch (IOException e) {
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
}
Then he gives me some exception:
