Nice getting-started article on using JConsole when developing MBeans

This article by D J Walker-Morgan covers how to use JConsole to see VM information, and especially how to write an MBean and attach JConsole to check it out. The only weird thing is the idea of calling a class WatchMeMBean and the corresponding MBean interface WatchMeMBeanMBean. I think I'd have used WatchMeManager and WatchMeManagerMBean.
