Hi,

I am getting this error after installing the Insight agent on Jboss 5.1.2 server.. Here is what I have done so far:
1. I installed the dashboard on a tc server.
2. Then downloaded the agent jar from "Administration" tab.
3. installed the agent jar on jboss's server directory.
4. the agent got installed successfully.
But then when I restart jboss server, I am seeing this error in the logs. Can you let me know what is missing?

Thanks for your help!!
