Question

Is there an easy way for me to identify which page caused a 500 error from a JSP 500 page? I’m on Google AppEngine in Java. My /500 page is served by a jsp. I’ve tried request.GetRequestURI() & request.GetRequestURL(), but it seems to just tell me I’m on mysite.com/500 which makes sense, but isn’t helpful.

Answer 1

This information is stored in the request scope with the key javax.servlet.error.request_uri.

So, this should do:

<p>Request URI: ${requestScope['javax.servlet.error.request_uri']}</p>
