I’ve put together a screen cast showing how to configure Tomcat and VisualVM for a secure JMX connection using self-signed certificates and a password. You can download it as a Quicktime video here:

Managing Tomcat with JMX (43.4MB, 1024×768)

This is a slightly cleaned-up version of some video in a talk I gave at SpringOne 2GX last week entitled Grails in the Real World. The talk was a summary of my experiences as a Grails developer and trainer, including a few tools and techniques I think are helpful when using Grails successfully in the wild. I talked a lot about Liquibase, some common GORM pitfalls, how to approach training and advocacy of Grails, and of course, how to use JMX.

Even though JMX is a very mature technology, getting this kind of thing to work is a perennial pain for users of any application container and web framework. I hope this quick video helps you out. Let me know how I could have improved it!
