Currently the XMPP transport works best with the Smack library as a client, that's certainly the most tested:
https://svn.apache.org/repos/asf/activemq/trunk/activemq-xmpp/src/test/java/org/apache/activemq/transport/xmpp/XmppTest.java With other clients your mileage may vary, it's likely in your case your client is reporting this error because the XMPP transport is throwing an exception when your client sends it's username/password, that should show up in the activemq log if you turn up logging for the xmpp transport packages. Also some clients have a debug console that'll let you see the XMPP traffic which could help if you want to look into it further.
