ContentHandling JSP Page Errors Any number of jsp error handling and debugging exceptions can arise when a JSP page is executed.
Jsp Error Handling Example
To specify that the web container should forward control to an error page if an exception handling in jsp exception occurs, include the following page directive at the beginning of your JSP page: <%@ page errorPage="file-name" %> The Duke’s Bookstore application 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, error handling servlet 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: BufferingNext: Creating Static Con

Author: Deron Eriksson Description: This Java tutorial describes how to create a JSP error page error handling 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 is not caught, you will typically see the result featuring the exception displayed in your browser window, jsp error handling 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.
