Thread: problem chatting with smack api with openfire server

I want to connect openfire with samck API and then chat with another user. For that i created user in openfire. And i can login to them from the code below. But i cannot add two user as friends.

I ran this code twice for different user in different pc and also in same pc.

I added them as friend by logging on openfire sever. I did it manually. so the code shows the buddy list. But cant send any message to the budies.

i found this code from here
[link]http://www.javaprogrammingforums.com/java-code-snippets-tutorials/551-how-write-simple-xmpp-jabber-client-using-smack-api.html[/link]

When i send message to one of the buddy from another buddy it sends successfully but then receive error message in smack debugging window.



This is the error message :

This is the java code to connect smack and openfire :
