Java? and JMX

Heather Kreger was the original JMX evangelist at IBM. A founding member of the JMX expert group, she personally contributed ModelMBeans to the JMX specification and is currently applying management to Web services technologies. Ward Harold is the lead architect for Tivoli's implementation of JMX, TMX4J. He is a member of the current JMX expert group. Leigh Williamson led the design and implementation of the WebSphere Version 5 new administrative architecture.
