Hi,
I tried unsuccessfully to write a servlet that simply
forwards the request to another jsp page (test.jsp) to
be proccessed. The test.jsp is a simple PURE html page
that just prints something. Here's the code:
=====================
package workflow.servlet;
import javax.servlet.*;
import javax.servlet.http.*;
public class TestServlet extends HttpServlet{
public void service (HttpServletRequest req,
HttpServletResponse res) throws ServletException,
java.io.IOException{
RequestDispatcher rd =
getServletContext().getRequestDispatcher("/workflow/test.jsp");
rd.forward(req, res);
}
}
===============================
I kept getting the following error message:
-------------------------------
500 Internal Server Error
The servlet named Test at the requested URL
http://sabrejspServlet
reported this exception:
java.lang.NullPointerException. Please report this to
the administrator of the web server.

---------------------------------------
However when I rewrote the servlet to forward the
request to an html page (test.jsp above saved as
test.html), the message is displayed correctly.
Please, help.
I'm using NT, jws 2.0, and servlets 2.1.
Thanks,
Kachana
