in the servlet code if the user does't exist i'm using requestdispatcher with error msg servlet if(res.next()) { if ((thisname.equals(res.getString("username"))) && (thispwd.equals(res.getString("password")))) { session.setAttribute("username", request.getParameter("username")); response.sendRedirect("login-success.html"); } else{ session.invalidate(); request.setAttribute("errorMessage", "Invalid user or password"); RequestDispatcher rd = request.getRequestDispatcher("/login.jsp"); rd.forward(request, response); } but thing is<%=request.getAttribute("errorMessage") %>

. how do i do it? or is there a better way jsp servlets share|improve this question asked Feb 20 '14 at 9:38 Rajshekar Targar 623412 Here the jsp for example runs just as a static html in case of h2, give a condition that returns the value in h2 only after the submit is done. posting the full jsp and servlet would be helpful in solving your issue. –user2423959 Feb 20 '14 at 9:50 add a comment| 1 Answer 1 active oldest votes up vote 3 dowhere for a quick overview of the site Help Center Detailed answers to any questions

Author: Deron Eriksson Description: how to This Java tutorial describes how to create a JSP error page to handle exceptions. Tutorial created using: Windows XP || JDK 1.5.0_09 || Eclipse Web Tools Platform 2.0 (Eclipse 3.3.0) || Tomcat 5.5.20 Page: 1 2> When an exception is thrown in your web application and it how to display is not caught, you will typically see the result featuring the exception displayed in your browser window, as shown here: Rather than displaying the above default page when an exception occurs, you can redirect the user to a custom-written error page for a particular type of exception. You can do this via the error-page element in web.xmlW, in which you can specify an exception-type and the location of the resource where a user should be sent if an error occurs. In this example, I specified the exception-type as java.lang.Throwable so that all exceptions would be sent to the error.jsp page.

In this article, Drew Falkman shows you how. This sample chapter is excerpted from Drew Falkman's JRun Web Application Construction Kit (Que, 2001). This chapter is from the book This chapter is from the book JRun Web Application Construction Kit Learn More Buy This chapter is from the book This chapter is from the book JRun Web Application Construction Kit Learn More Buy The Web application framework provides a simple way to customize the look of error messages that can occur while users are accessing your pages. As you know, error messages are thrown because of syntax problems in your code, because of database connection problems, or just because the user has left out one or more required fields while filling out a form. The application framework enables you to customize any of these error messages. You can even hide them from the user's view entirely, if you want. This enables you to maintain a consistent look and feel throughout an application, even when those dreaded error messages are thrown. Creating an Error Page The first step in outputting errors is to create an error page. Take a look at the error1.jsp page shown in Listing 1.
