I'm working on an installer which will install a slightly cut-down version of Tomcat for out webapp: if people want the full thing, they can install it themselves and plug our webapp in in the normal way. We don't use any JSPs, so I don't really need jasper.jar. Is it sufficient to remove the jar file and all the references to jasper and jsps in conf/web.xml? I can't find anything jsp-specific in server.xml. Jon Skeet
