Error or exception handling is an important, but often ignored, part of any application. And although there’s a lot to be said on the topic I’m going to web xml error 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 (the most common being 404 and 500). An example snippet that can be applied to the web.xml is below: Web Xml Error Page Jboss
