servlet forward: things happen twice

[Yong Wang <wymz@yahoo.com>]

Hi, I wonder if anyone could spot the problem here bcz
I am sure it is something very simple that I
overlooked:

I have three servlets, A, B and C, where A forwards to
B or C based on some flags in request parameter. But
when A forwards to B, somehow both servlet A and B get
called twice by only a single get request. The
environment is tomcat 4.1.

Servlet A
=========
	public void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException
	{
		doPost(request, response);
	}

	public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException
	{

		String key = (String) request.getParameter("key");
		String idx = (String) request.getParameter("index");

		try
		{
			if (key != null && idx != null) {
				RequestDispatcher rd =
getServletContext().getRequestDispatcher("B");
				rd.forward(request, response);
			} else {
				RequestDispatcher rd =
request.getRequestDispatcher("C");
				rd.forward(request, response);
		} catch (Exception e) {
			;
		}

Servlet B
=========

	public void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException
	{
		doPost(request, response);
	}

	public void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException
	{
		String key = (String) request.getParameter("key");
		String idx = (String) request.getParameter("key");

	// do some processing and output to response...
	}

Servlet C (actually a JSP)
===========
code omitted.

I would appreciate any insight. pls email me directly
if you want to see the entire source listing. Thanks!
