PeterJ- Sorry for all the red ink, I thought it would make it easier to differentiate between my text and the error message. Thanks for the jar search utility tip... works great. I have created a JMX program that basically monitors directories for content and notifies Agents to act upon them. I was asked to convert it to using your Microkernel, now the Microcontainer, and I am assuming you provide comparable JMX functionality (MBean notification, register and unregister, etc..). I look forward to reading your documentation. Regards, GMarsh View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4194707#...
