RequestDispathcher

[vinay bedidha]

i want to transfer control from a servlet to JspPage("Home.jsp")
iam getting a problem when using
RequestDispatcher rd=getServletContext().getRequestDispathcher("/Home.jsp");
rd.forward(request,response);
iam getting NullPointerException problem.if i use response.sendRedirect("/Home.jsp"); it's working fine.
what's the problem with RequestDispatcher?

Hi Vinay,
Use the following code
RequestDispatcher rd=request.getRequestDispathcher("/Home.jsp");
rd.forward(request,response);
dont use servlet context.
Thanks
Deepak

hi,
Normally I use this approach
RequestDispatcher rd=getServletContext().getRequestDispathcher("/xxx.jsp");
Using
RequestDispatcher rd=request.getRequestDispathcher("/xxx.jsp"); is better approach??
Thanks for your time,
