现在我更新$ C $这些行C投掷NPE
Now my updated code throwing NPE in these lines
Message msg = new Message(to, Message.Type.chat);
msg.setBody(text);
connection.sendPacket(msg);
首先，它会打开对话框，从那里，我们需要输入用户ID和PWD，然后要输入的好友列表中的用户名，然后味精，然后点击发送这样我试图,,,我打字的用户名称是否正确太多，但其表现为空ponter例外，同时点击发送按钮
First it will open the dialog box from there we need to type the userid and pwd and then wants to type the username of friends list and then msg and then click send like this i am trying,,,i am typing the user name correctly too,but its showing NUll ponter exception while clicking send button
推荐答案
我想问题可能是你有2个jar文件的地方，包括相同的包和类。所以，我强烈建议你检查你的所有jar文件的再次并删除任何人，这是造成这个问题。
I think the problem might be you have 2 jar files somewhere that include the same package and classes. So i strongly recommend you to check your all jar file's once again and delete anyone which is causing the problem.
删除这个包从JAR文件中的一个将问题解决了。
Deleting this package from one of the JAR files will solved the problem.
