Hi James, I haven't gotten to the MBeans yet. Do you have any good reference URLs (tutorials) on them ?
I have downloaded JBoss and Blazix. So far, I have concentrated on porting samples from Weblogic stuff to Blazix. There are some minor porting issues, but it is helping me to understand the bigger EJB picture (what goes where and how to do it). I am using Blazix because my base station is Windows ME and Weblogic does NOT recommend using it. I went to Sun and looked at the JMX material, but so far no lights have gone on as to how to use it with JESS.
