An application called "External" is built with JSF technology. Our module ,

Interface Servlet receives the request from External module, and adds a URL
parameter ( like http://localhost:8080/Controller?id 0&value=300) and

How do you add the parameter?

does a RequestDispatcher.forward.

....

Now the million dollar question, the internal module takes
request.getParameter("id") and this gives me a NULL!!!! When I print

Are you sure it doesn't give you a null?

request.getParameterMap, I get so many parameters which were set by External
in the request. Note that External does a "POST" to interface servlet, which
in turn again does a "forward" to controller.

Perhaps the URL was added as an attribute, not a parameter?

One small doubt I am getting - Is JSF ServletRequest different from
HttpServletRequest ? Then the method of the controller (doGet/doPost) could
not have been called right? Or a new instance is getting created? Then how I
am getting query string... ahhhh

A request is a request is a request.

The JSF Faces Servlet grabs it first. The Sun Java EE tutorial goes into
great detail about the JSF life cycle, plus there are many articles out there
about it.

SSCCE, please.
