Cool.
Thanks for the helpful reply.
I just wish I could have figured out how to word my question better so
as to elicit this helpful information to start with -- instead of
getting told I was posting to the wrong group and chasing my tail with it.

Well, there is interest - the tomcat-lite in the sandbox does allow that (
there is even a TomcatLiteNoConnector unit test ).
The code is broken right now - in process of moving part of it to trunk and
adjusting it to be easier to digest. Will take quite a while
before it's ready for an official release - but ability to run 'in process'
( either as unit tests, or as you describe ) is one of the goals.

Having looked into this further it seems clear Tomcat is not designed to
provide any reasonably reliable / easy-to-use means of making a JSP or
servlet request from within the process but outside a connector request
thread. If one wants to properly do this it would appear one has to call
org.apache.catalina.core.StandardEngineValve.invoke() oneself -- with Tomcat
Request and Response objects. Ideally there would be a way to instead
implement HttpServletRequest and HttpServletResponse as desired, mimicking
remote client to the degree needed, get a RequestDispatcher [from a cached
ServletContext], and call forward(), for instance -- possibly capturing the
context class loader in a ContextListener and setting that as the context
class loader around all this. That /kind of/ works for include(), but skips
all servlet filters and does not work at all for forward().
I fully realize the servlet specification spells out no such mechanism, but
I believe there is a clear gap here. One should be able to embed Tomcat in
an application and /easily /invoke a JSP or servlet to produce an HTML
e-mail body, for instance. This should involve a minimum of Tomcat-specific
APIs.
It is hard to understand why one should be unable to re-use one's JSPs and
servlet investment to produce HTML for other purposes than HTTP responses.//
It is also quite unclear to me why there appears to be no interest in
addressing this need.

I find no user documentation on anything like what I'm looking for.
I thus am /assuming/ this would be an extension to Tomcat and thus more
appropriate for a development forum than a user forum.
I want to call JSPs, etc, from Java code to generate HTML. I'm not
looking for a web server connector -- that would be a clear user group
question.

Is there an in-process connector for Tomcat somewhere out there?
Specifically I want to be able to embed Tomcat and use JSPs, etc, to
generate HTML but without requiring loopback HTTP(S) requests.
Does such a thing exist? If not, would this be hard to add?
Pointers and suggestions would be much appreciated.
There is a user list for questions on Tomcat usage.
