Hi Antonio,
It seems the code you're interested in is in the method
messageReceived(..). You're actually printing the message to the
console. I guess that code should look like this:
public void messageReceived(int Id, Message message){
MultiMsg msg = (MultiMsg)message;
jTextArea1.append(msg.toString());
}
The instanceof test for MultiMsg is unnecessary since you already to an
explicit cast before that. I haven't checked the whole code, but most
likely you will ever get Messages of type MultiMsg if you have
registered your message handler only for MultiMsg message types.
Cheers,
Urs
PS:
I use a thunderbird as a mail client and by default I set it to display
messages as text only. For some unknown reason your mail client sends
HTML messages that don't show properly in text-only mode. It would help
me a lot to read your mails if you could change this behavior.
