create a JSP error page to handle exceptions? Author: Deron Eriksson Description: This Java tutorial describes how to create a JSP error page to handle exceptions. Tutorial created jsf error page example 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, as shown here: Rather than displaying jsp error page directive 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.

Same explanation is also applicable for JSP pages also and that's why error page Java EE provides a clear approach for exception handling in JSP using JSP error pages.To handle exceptions thrown by the 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 jsp error page 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 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.
through exception handling in JSP, let's understand what is exception and how it is different from errors. Exception: These are nothing but the abnormal conditions which interrupts the normal flow of execution. Mostly they occur because of the wrong data entered by user. It is must to handle exceptions in order to give meaningful message to the user so that user would be able to understand the issue and take appropriate action. Error: It can be a issue with the code or a system related issue. We should not handle errors as they are meant to be fixed. Methods of handling exceptions: We can handle exceptions using the below two methods. Exception handling using exception implicit object Exception handling using try catch blocks within scriptlets Exception handling using exception implicit object In the below example - we have specified the exception handling page using errorPage attribute of Page directive. If any exception occurs in the main JSP page the control will be transferred to the page mentioned in errorPage attribute. The handler page should have isErrorPage set to true in order to use exception implicit object. That's the reason we have set the isErrorPage true for errorpage.jsp. index.jsp <%@ page errorPage="errorpage.jsp" %>
