Hi,
I have searched through the list and have seen and tried numerous different
responses to this problem but with no luck. I have seen the discussion on
getServletContext(), but I know that I am missing something real basic here.
My problem is that I am trying out the example from Java World which uses a
Servlet to redirect to different jsp pages. I am wondering if it is a bug with JWS2.0
or not. I am using JWS2.0 and Win98.
If I call the page first in the browser like this
http://karldii:8080/examples/jsp/shopping/Checkout.jsp, I don't get the error when I
use forward. I assume this happens because it is currently in memory.
Also, the examples/jsp/... directory is at the next level below the JavaWebServer2.0
directory.
I am trying to redirect my response to a new .jsp page using the usual
RequestDispatcher rd =
getServletContext().getRequestDispatcher"/examples/jsp/shopping/Checkout.jsp");
rd.forward(req,res)
I get the following error
500 Internal Server Error
The servlet named ShoppingServlet at the requested URL
http://karldii:8080/servlet/ShoppingServlet
reported this exception: . Please report this to the administrator of the web server.
