You can map an error handling page in the deployment descriptor.

But be aware that showing exceptions to uses is generally considered a bad practice. Rather, it is more customary to log the exceptions for the developers, and to show the users a more generic "sorry, but something went wrong" message.

As Bear suggested, you can configure errors and exceptions in web.xml. Please see the link
