You can create a reader for this purpose. I needed something like that to
get direct output from a JSP page (that is generating HTML, not XML) and
have implemented the JSPReader. Now you can use it like this:

 <map:match pattern="old_application/**">
    <map:act type="checkSession"/>
 <map:read src="/jsp/page.jsp"/>
    <map:redirect-to uri="login.html"/>

So, I hope you got the idea.

Btw, developers, there are ServletGenerator and JSPGenerator componenets
that implement almost the same thing: get output from a servlet then
generate XML from it. JSPGeneretor uses JSPEngine for that. Maybe it'll be
better to have something like ServletComponenet and use it either in
generators or readers that have to interact with other servlets?
