When JSP Error page is translated to servlet code, it extends org.apache.jasper.runtime.HttpJspBase in Tomcat.Error Page Deployment Descriptor ConfigurationMost of the times, we have a common error page that we want to For example, if a stack overflow occurs, an error will arise. Let's see the simple example: There are 4 files: web.xml file for specifying the error-page element index.jsp for input values process.jsp for dividing the two numbers and displaying the result error.jsp In this example, I specified the exception-type as java.lang.Throwable so that all exceptions would be sent to the error.jsp page. java.lang.Throwable /error.jsp I created the error.jsp page shown below.

To specify that the web container should forward control to an error page if an exception occurs, include the following page directive at the beginning of your JSP page: <%@ page Opps... We can configure JSP error page to handle other error codes like 404 also.Let's see how all these fit together in a web application.We will create a simple web application JSPExceptionHandling If any exception occurs in the main JSP page the control will be transferred to the page mentioned in errorPage attribute.

JSP gives you an option to specify Error Page for each JSP. This page has almost same logic which we have used in above example, but it has better structure and it provides more information: <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@page isErrorPage="true" %> 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 If you want to handle all the exception, you will have to specify the java.lang.Exception in the exception-type element.

Thus, ${pageContext.errorData.statusCode} retrieves the status code, and ${pageContext.errorData.throwable} retrieves the exception. sendErrorRedirect looks like this: protected void sendErrorRedirect(HttpServletRequest request, HttpServletResponse response, String errorPageURL, Throwable e) { try { request.setAttribute ("javax.servlet.jsp.jspException", e); getServletConfig().getServletContext().getRequestDispatcher(errorPageURL).forward(request, response); } catch (Exception ex) { putError("serXXXXX.sendErrorRedirect ", ex); }

Following is an example to specifiy an error page for a main.jsp. You can have following type of errors in your JSP code: Checked exceptions: Achecked exception is an exception that is typically a user error or a problem that cannot be foreseen Let us put following code in main.jsp: Try...Catch Example <% try{ int i = 1; i = i / 0; out.println("The answer is " + i); } The specification of the redirection into the page where the Java exception can occur.
