Implicit /servlet path

["Rousseau, John" <JR...@silverstream.com>]

I'm looking at the ServletContext.GetRequestDispatcherTestServlet
test (but I see the same thing with other tests).

It's doing a getRequestDispatcher() on
"/servlet/tests.javax_servlet.ServletContext.GetRequestDispatcher". 

I don't see "/servlet" in the deployment descriptor, nor do I see
any documentation about getRequestDispatcher taking a '.' separated
class name. There is clearly no "/servlet" directory in the WAR.

Is there an implicit mapping that Apache uses, or am I just missing
something?

Thanks!

Yes, Tomcat uses a default mapping for "/servlet" to an invoker servlet
that takes the "path info" part of the path and tries to find a servlet
with that <servlet-name>, or a servlet with that class name.

This is an issue I have raised with the authors of the servlet tests,
because there is no requirement in the spec that a servlet container
provide such an invoker.  My understanding is that the tests are going
to be changed to provide explicit <servlet-mapping> entries for all
addressable servlets, and the tests will use those paths.
