What you describe isn't a bug -- it's a direct consequence of the way auto-mount works in the "appBase" directory of a Host (i.e. the "webapps" directory).
Normally, Tomcat examines all the contents of the "webapps" directory, and (if it's a WAR or a directory) tries to automatically mount a webapp with the corresponding name as the context path -- thus the "examples" directory is automatically mounted at context path "/examples", the "tomcat-docs" directory is automatically mounted at "/tomcat-docs", and so on. The root directory is a case where we can't do this -- conforming to this pattern would require us to have a zero-length pathname, which most OSs are not too happy with. Therefore, there is a special case that the directory name ROOT will be mounted as the root webapp. If you don't want two instances of you webapp, it's really very simple: * Don't change the docBase for the ROOT partition * Use an absolute docBase that points to a directory not under webapps. By the way, you can cause the same sort of problem with any other context that is explicitly configured in server.xml -- for example, add a new <Context> entry just before the one for "/examples" like this, and see what happens:: <Context path="/foo" docBase="examples"/> Craig On Mon, 29 Jul 2002, peter lin wrote: > Date: Mon, 29 Jul 2002 08:48:38 -0400 > From: peter lin <[EMAIL PROTECTED]> > Reply-To: Tomcat Developers List <[EMAIL PROTECTED]> > To: Tomcat Developers List <[EMAIL PROTECTED]> > Subject: ServletContextListener bug #11043 > > > I've posted this question last week and talked to Remmy, but Remmy is > busy with moving.
