Issues with JVM monitors

Issues with JVM monitors

I'm attempting to set up Application Manager to monitor some simple JVM data. I repeatedly run into a message (when I try to test authentication to the monitored server) that says " Failed. Exception while getting the MBean server reference ". I am on the correct monitoring port for this JVM, and I have connectivity (not firewalls blocking) as I can open a telnet connection on that port. Both the monitoring server and target are RHEL 6 servers. What am I doing wrong here? 

Thanks,
