Recently I spent some time working on improving my init scripts for Tomcat 6.x in a production environment running Ubuntu. One of the major problems we had encountered was that occasionally Tomcat refuses to shut down completely and requires a kill -9 to stop it. The standard init scripts I had seen didn't solve this problem at all.
Laliluna has a great article that focuses on RedHat, CentOS and Fedora. Unfortunately, their scripts didn't work correctly under Ubuntu 8.04 LTS. As a result, I spent some time modifying their scripts to get them to work correctly under Unbuntu. Many thanks to Laliluna for doing the heavy work.
Without any further ado, here's what I put together:
