Hello,
I do it as follows:
1- Instantiate the bean in the servlet
2- Set it in the request, logical name must match the ID field in the
<jsp:useBean ID> tag
3- Include the target jsp, (forward may not be possible)
// in the Servlet
TodayInfo todayInfo = new TodayInfo(); request.setAttribute("today",
todayInfo);
getServletConfig().getServletContext().getRequestDispatcher("/jsp/TopSummary.jsp").include(request,
response);
// in the JSP page
<jsp:useBean id="today" class="measureBeans.TodayInfo" scope="request"/>
I hope it helps
