Handling Errors And Exception In Jsp
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 a particular error code occurs in the context of your JavaSW web application, such as a 404 (Not Found) or 500 (Internal Server Error), it is possible to send the user to an error page. The web.xml error-page location error code and the page location where the user should be sent in the event of that error can be specified in an error-page section in web.xmlW. Below, we see that when a 404 error occurs, the user is to be redirected to the error-404.jsp. Section of web.xml

Jsp Error Page Status Code
can arise when a JSP page is executed. To specify jsp error page redirect that the web container should forward control to an error page if an exception jsp error handling and debugging 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 http://www.avajava.com/tutorials/lessons/how-do-i-create-a-jsp-error-page-to-handle-particular-error-codes.html 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 https://docs.oracle.com/cd/E19316-01/819-3669/bnahi/index.html 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.
