pagecontext request dispatcher servlets

I am trying to forward a request using "RequestDispatcher". I have JSP pageContext object. I tried to forward my request to my servlet "MyServlet" using the following code. I set some attributes in my request and forwarded it. But i am not able to access those variables in my servlet class.

My code : 

pageContext.getRequest().setAttribute("AValue","A");
pageContext.getRequest().setAttribute("BValue", "B");

ServletContext context= pageContext.getServletContext();
RequestDispatcher rd= context.getRequestDispatcher("/MyServlet");
rd.forward(pageContext.getRequest(),pageContext.getResponse());

Help me !! Thanks in advance.

When dynamically including or forwarding to a servlet from a JSP page, you can use a jsp:param tag to pass data to the servlet.

A jsp:param tag is used within a jsp:include or jsp:forward tag. 

<jsp:include page="/servlet/MyServlet" flush="true" >
  <jsp:param name="AValue" value="A" />
  <jsp:param name="BValue" value="B" />
</jsp:include>

Here is source docs

The use of scriptlets <% %> in JSP is indeed highly discouraged since decade.
