Problem with deployment-descriptor's error-page mapping

[Robert Paris]

I've set the error page as such (in web.xml):

   <error-page>
    <location>/error.html</location>
<error-code>500</error-code>
    </error-page>

but that error code gets thrown and it never goes to my error page. however, if I set "errorPage=error.html" in the page directive of a JSP page, it goes there on an error, but not if I use the error-page XML tags. why isn't the web.xml mapping it up?

Just a wild swing here - what if you swapped the <error-code> and <location> tags around in the deployment descriptor? XML is sometimes fussy about the order of its definitions.

hey mark,
thanks for the reply. unfortunately it didn't work. What's interesting is that if i switch the error-code for the exception-type tag, then it works. But I wanted to be able to send specific codes to diff pages. I guess I'll have to throw different errors instead.

Were you using HttpServletResponse.sendError() to create the error code?

[Robert Paris]

no, should I have? I just did "throw new..."
So it will go to the correct error-code page only if you use sendError? Hmmm, makes sense. Thanks!
