configure default error page in web.xml
HI,
I have a request to catch a Java Exception in the servlet and display an error page. The functionality requires that we display different error message for different exception.
A way to do this is to put try and catch logic in servlet, and if an Exception is caught, I do request.setAttribute("javax.servlet.jsp.jspExcetion",e), and then forward to jsp error page, where we check the type of exception implicit object. Based on this type, we display different error message. This is fine, but we are not going to use this approach.
The other way is to configure web.xml. We can configure an error page for specific Java exception. If the specific exception is raised to the web container, the configured error page will get called. My question is that is there any body doing this way successfully?
Thanks.
Larry Zhang

You can certainly combine approaches to let a Struts action handle pretty much
any exception in the app. In web.xml:
<error-page>
<exception-type>java.lang.Exception</exception-type>
<location>/do/error</location>
</error-page>
Where "/do/error" is obviously a Struts action mapping path.
Quoting Mike Jasnowski <mj...@bea.com>:

It's too bad you couldn't forward that to an Action, which could then
forward it to a custom page, or rethrow so a Struts exception handler could
grab it.
