Well, I can't really provide details, I was sharing something that I had bookmarked, not something I've implemented.
Looking at the error, though, it would seem to me that you have to declare your class something like org.my.class.PidLifeCycle, not just "PidLifeCycle". Tim's post was an example, I don't know that he was claiming that the code snippets he posted were exactly correct. "ClassNotFoundException" is pretty basic, and self-explanatory. Tomcat is just saying it can't find your class, and/or its declared incorrectly in server.xml. Check the docs: http://jakarta.apache.org/tomcat/tomcat-4.0-doc/config/context.html especially the section entitled "Lifecycle Listeners". When you get it working, how about posting a HOWTO?
