How does a servlet communicate with a JSP page ?

Call JSP from servlet

request.setAttribute("fBean", f);

getServletConfig().getServletContext().getRequestDispatcher("/jsp/Bean1.jsp")

      .forward(request, response);

Use bean or values in JSP which is set in servlet

<jsp:useBean id="fBean" class="genius.FormBean" scope="request" />

<jsp:getProperty name="fBean" property= "name" />

<jsp:getProperty name="fBean" property= "addr" />
