Nikhil Menon Ranch Hand Posts: 70 posted 11 years ago Hi sitaram, To call Jsp Error page from servlet you need to do a trick. http://www.jguru.com/faq/view.jsp?EID=1347 First of all we should know If the source of the exception was a JSP page, the Web container also stores the exception as a request attribute called "javax.servlet.jsp.jspException" So if you want from Servlet to JSP-Error-Page then you have to set the exception in the same way as the Web Container does ie in https://coderanch.com/t/359893/Servlets/java/jsp-error-page-servlet the catch block you set : request.setAttribute("javax.servlet.jsp.jspException"); then use RequestDispatcher to forwrd to your error page public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { try { // Do your stuff here which may result in Exception/Error // [B]You should not open an OutputStream or PrintWriter[/B] } catch (Throwable e) { request.setAttribute("javax.servlet.jsp.jspException", e); RequestDispatcher dispatcher = request.getRequestDispatcher("errorPage.jsp"); dispatcher.forward(request, response); } } Remeber: You will get an IllegalStateException if you had opened OutputStream or PrintStream before forwarding Adeel Ansari Ranch Hand Posts: 2874 posted 11 years ago why calling error page.
