JMX start() method not working on MDB

[eserrano]

I have a MDB that shows up in the JMX console and the stop() method works fine but when I invoke (press) the start() method, it thows the following error. I am running JBoss 3.0.8 on WinXP. My goal is to be able to make this MDB start and stop delivery of the messages on the fly.

Thanks,
Ed
