Author: Deron Eriksson Description: This Java tutorial describes how http://www.javatpoint.com/exception-handling-in-jsp to create a JSP error page 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 http://www.avajava.com/tutorials/lessons/how-do-i-create-a-jsp-error-page-to-handle-exceptions.html result featuring the exception displayed in your browser window, 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.

Error or exception handling is an important, but often ignored, part of any application. And although there’s a error handling in lot to be said on the topic I’m going to cover only a few of the most critical cases in J2EE Web applications. Essentially, one of the biggest worries about exception handling is that you don’t actually handle the exception. Instead, your code − or the code of some 3rd party library you’re using − allows an exception to bubble up. Once the exception reaches the boundary of your application and enters the container, the specific container/application server you are using determines what semantics are applied in handling the exception. Often times, by default, a standard error page is applied and the exception stack trace is printed on the screen in all its glory. This is definitely a problem, because it gives attackers a lot of information about the system, and can lead to further attacks. What should I do about it? Handling this issue is fairly straightforward. The basic advice is to provide error handlers for at least java.lang.Throwable (catches any Java exceptions or errors), and provide more specific handlers for individual exceptions and http error codes (t
