Nullpointer when forwarding to JSP

Question

Hello...
I'm recieving a Nullpointer exeption in the line marked with 1):
private void gotoPage(String address, HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
1) RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(address);
dispatcher.forward(request, response);
I'm trying to forward to address /JSP/LoginSuccess.jsp but a plain HTML file also gives an Nullpointer.
Stranges thing is. I'm receiving this exception since i changed the init of my servlet from having no arguments to having init (ServletConfig config).
Any ideas?
Thanks very much.

arguments to having init (ServletConfig config).
The init(config) is called bythe servlet container and the servlet stores the config and ServletContext objects but by overriding this method you have hidden the code where the ServletContext object gets stored so your call to getServletContext now returns null. Make sure you call the super.init(config) method.
From the servlet api:
public void init(ServletConfig config)
throws ServletExceptionCalled by the servlet container to indicate to a servlet that the servlet is being placed into service. See Servlet.init(javax.servlet.ServletConfig).
This implementation stores the ServletConfig object it receives from the servlet container for later use. When overriding this form of the method, call super.init(config).
