Hi Mark T, Thanks for the information about removing the <WatchedResource>... entry from $CATALINA_BASE/context.xml. While that prevents a web applications from restarting when modifying the web.xml included with it, it does not prevent restarting of all web applications when modifying the web.xml in the server's conf folder.
FYI, we currently appear to be using Tomcat 7.0.6, though I suspect we'll be upgrading to the latest sometime soon. ~Mark
