probably a bit late but just came across this now! I've been looking for a way to restart tomcat programmatically as well. We have a problem where out tomcat instances lock up because we have to use a dodgy odbc driver for some of the databases we access.

There is an mbean Catalina:type=Engine that has two operations start and stop. that should do it i imagine!
