Support for query parameters in the ServletContext.getRequestDispatcher,
i.e. the servlet code used by JSP to implement <jsp:include>, is being
considered for the Servlet 2.2 API and hence for JSP 1.1. For the time
being you should be able to pass the information as HttpRequest attributes,
setting them in a scriptlet in Main.jsp and reading them with a scriptlet
in A.jsp and B.jsp. Alternatively I believe you can pass the information
as Beans with request scope (this should actually generate code for setting
and reading HttpRequest attributes).
