Question:

How do I reference a servlet programatically?

Answer:

You should use the servlet mapping, which relates to the servlet invoker object. It makees it easier to refer to to servlet object, as it is not necessary to hard code path references which may change after deployment.

For example:

<%

RequestDispatcher rd = request.getRequestDispatcher("/servlet/jspservletservlet.Servlet1");
rd.include(request, response);

%>
