Servlet Chaining...
Hello
I try to use Servlet Chaining with Tomcat.
Can I do that with a tag in the web.xml file (with <servlet-mapping> for
example), or must I modify my Request parameters?? does anyone know how to
do that???
I have a Servlet that generates an complete and valid XML file from a
database, and this file must be processed by the Cocoon servlet and then be
returned to the client. That's it. Can anyone help me please???
Thanks.

No, it doesn't work, because the HttpServletRequest class used in
HttpServlet doesn't implement the getRequestDispatcher method...
But it we can make your idea work, I don't understand how my XML file is
sent to the cocoon servlet... My XML file is printed do the response
(out.print(String);), and with the forward() method, the XML data is not
sent.. How does it work??

Could you use a request dispatcher to forward the
request to the second servlet?
>>From the first servlet's request object you could code
this:
RequestDispatcher rd = req.getRequestDispatcher("path
to second servlet");
rd.forward();
