ContentHandling JSP Page Errors Any number of jsp error page example exceptions can arise when a JSP page is executed. web xml error page To specify that the web container should forward control to an error page if jsf error page an exception occurs, include the following page directive at the beginning of your JSP page: <%@ page errorPage="file-name" %> The Duke’s Bookstore application jsp errorpage page tut-install/javaeetutorial5/examples/web/bookstore2/web/template/preludeErrorPage.jspf contains the directive: <%@ page errorPage="errorpage.jsp"%> The following page directive at the beginning of tut-install/javaeetutorial5/examples/web/bookstore2/web/error/errorpage.jsp indicates that it is serving as an error page: <%@ page isErrorPage="true" %> This directive makes an object of type javax.servlet.jsp.ErrorData available to the error page so that you can

retrieve, interpret, and possibly display information about the cause of the exception in the error page. You access the error data object in an EL (see Unified Expression Language) expression by way of the page context. Thus, ${pageContext.errorData.statusCode} retrieves the status code, and ${pageContext.errorData.throwable} retrieves the exception. You can retrieve the cause of the exception using this expression: ${pageContext.errorData.throwable.cause} For example, the error page for Duke’s Bookstore is as follows: <%@ page isErrorPage="true" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
: ${pageContext.errorData.throwable.cause} Note – You can also define error pages for the WAR that contains a JSP page. If error pages are defined for both the WAR and a JSP page, the JSP page’s error page takes precedence. Previous: Bu

Author: Deron Eriksson Description: This Java tutorial describes how to create a JSP error page to handle exceptions. Tutorial created using: Windows XP || JDK https://docs.oracle.com/cd/E19575-01/819-3669/bnahi/index.html 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 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, http://www.avajava.com/tutorials/lessons/how-do-i-create-a-jsp-error-page-to-handle-exceptions.html 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.

Same explanation is also applicable for JSP pages also and that's why Java EE provides a clear approach for exception handling in JSP using JSP error pages.To handle exceptions thrown by the error page JSP page, all we need is an error page and define the error page in JSP using jsp page directive.JSP Error PageTo create a JSP error page, we need to set page directive attribute isErrorPage value to true, then we can access exception jsp implicit object in the JSP and use it to send customized error message to the client.JSP Error Page ConfigurationWe jsp error page need to set page directive errorPage attribute to define the JSP that will handle any exception thrown by the JSP service method. 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 use for all the JSPs, so rather than configuring it in all the JSPs individually, we can define error page in web.xml with error-page element. 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 whose project structure will look like below image. The entry point of the application is index.jsp whose code is given below. <%@ page language="java" contentType="text/html; charset=US-ASCII" pageEncoding="US-ASCII"%>
