Tomcat error-page not working (was: RE: Tomcat and checked vs. unchecked exceptions)

I don't understand. :(  I don't know if this is related to the original
question, but I have this in web.xml:

   <error-page>
      <exception-type>javax.servlet.ServletException</exception-type>
      <location>/WEB-INF/jsp/exceptions/ServletException.jsp</location>
   </error-page>

(in the appropriate place, at the bottom just above </web-app>)

When this code executes:
   if ( report == null || report.equals( "" ) ) {
      log.debug( "doGet: no data!  Need to forward to an error page." );
      throw new ServletException( "No data found in HOLD file" );
   }

I _still_ get this in the browser:

type Exception report
message 
description The server encountered an internal error () that prevented
it from fulfilling this request.
exception 
javax.servlet.ServletException: No data found in HOLD file
	at edu.asu.vpia.webapp.PDFServlet.doGet(PDFServlet.java:94)

Yansheng Lin suggested using Struts declarative exception handling, but
this is a plain-old Servlet, not a Struts Action.

The same <error-page> tag works fine in a different webapp, I'm at a
loss as to why it fails in this one.  The JSP is present in the location
given in the tag.

What am I missing, why do I get a Tomcat-generated error page and not
the JSP I specified?

Wendy:

Here's your problem:

 >      <location>/WEB-INF/jsp/exceptions/ServletException.jsp</location>

JSPs can't be run from inside the WEB-INF directory. Try moving your 
jsp/exceptions directory up one level.
