Handling Errors And Exception In Jsp
to an error page if an exception occurs, include the following page directive at the beginning of your JSP page: <%@
Jsp Error Page Tag
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 jsp error page not displaying 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

Author: Deron Eriksson Description: This Java tutorial describes how to create a JSP to handle particular error codes. Tutorial created using: Windows XP || JDK 1.5.0_09 || https://docs.oracle.com/cd/E19316-01/819-3669/bnahi/index.html 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 error code and the page location where the user should be sent http://www.avajava.com/tutorials/lessons/how-do-i-create-a-jsp-error-page-to-handle-particular-error-codes.html 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

You can have following type of errors in your JSP jsp error page code: Checked exceptions: Achecked exception is an exception that is typically a user error or a problem that cannot be foreseen by the programmer. For example, if a file is to be opened, but the file cannot be found, an exception occurs. These exceptions cannot simply be ignored at the time of compilation. Runtime exceptions: A runtime exception is an exception that occurs that probably could have been avoided by the programmer. As opposed to checked exceptions, runtime exceptions are ignored at the time of compliation. Errors: These are not exceptions at all, but problems that arise beyond the control of the user or the programmer. Errors are typically ignored in your code because you can rarely do anything about an error. For example, if a stack overflow occurs, an error will arise. They are also ignored at the time of compilation. This tutorial will give you few simple and elegant ways to handle run time exception/error occuring in your JSP code. Using Exception Object: The exception object is an instance of a subclass of Throwable (e.g., java.lang. NullPointerException) and is only available in error pages. Following is the list of important medthods available in the Throwable class. SNMethods with Description 1public String getMessage()
Returns a detailed message about the exception that has occurred. This message is initialized in the Throwable constructor. 2publi
