Re: lost output including a servlet in a JSP which includes a JSP

[M.Hockings]

That would be what I tend to call a "named servlet".  I find that in a 
portal environment that named servlets that are not portlets do not seem 
to be allowed.  I want a solution that will allow me to pull in some 
utility content generation servlets without having named servlets.

The solution that I gave below seems to work OK for the servlets 
themselves but if they include another servlet or jsp then the output of 
that next level included thing appears to be discarded.

The servlet class should be mapped to a path in web.xml

Ok, I would tend to agree.  But, how can I get a request dispatcher 
without loading the servlet by classname?

i.e., RequestDispatcher rd = 
request.getRequestDispathcer("/servlets/my-servlet-classname");

This is all wrong. You need to get a RequestDispatcher via:
<jsp:include> or <jsp:forward>

RequestDispatcher rd = request.getRequestDispathcer(myPath);
rd.include(request, response);

that I won't go into please assume that in the environment that I 
wish this to run I cannot define a named servlet nor can I load by 
classname.

A simplified version of what I have been doing is below:
<%
Class c = Class.forName("name-of-the-servlet-class");
Servlet s = (Servlet) c.newInstance();
s.init(this.getServletConfig());
s.service(request, response);
%>
This sorta works.  That is, it will load and run the servlet and the 
output from the servlet is deliverd to the browser.  But if the 
called servlet class includes a .JSP then the output of that .JSP is 
never seen though if debugged it does run OK and produces output.  
The servlet itself is generated by compiling a .JSP with jspc. What 
am I missing.

I realize that this inquiry is not strictly Tomcat related but I 
figure that the people who will have the knowledge answer to my lost 
output mystery will be here!

Your thoughts on this problem are appreciated.
