Very Strange 404 to JSP with getRequestDispatcher().forward()
All,
I'm having a very strange issue with
request.getServletContext().getRequestDispatcher().forward(). It gives me
a 404 on a JSP page that if I go to directly, works fine. This is with
tomcat 8.0.30 on OSX on JDK :
ava version "1.7.0_65"
Java(TM) SE Runtime Environment (build 1.7.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)
What makes this a bit different is that the request object is wrapped with
a couple of implementations of HttpRequestWrapper. The methods that seem
to matter (getAttribute and setAttribute) are just passthroughs. After
doing some debugging, I've traced the main issue to the JspServlet where
the jspUri variable is being set to the original URI
(/auth/idp/MyIdP/completeFed) not the forwarded URI
(/auth/fed/postauthnresp.jsp). The request being passed into the
JspServlet's service method is the same request object as is being sent to
the forward method.
This code works perfectly well under Jetty as a frame of reference. Any
help would be greatly appreciated.
Thanks
Marc

Sounds like good advise.
Thanks

Your request wrappers store their own reference to a
HttpServletRequest in addition to the one stored by the
ServletRequestWrapper class.
My guess is that your issue will be solved if you either override
ServletRequestWrapper.setRequest() to update your request field, or
use ServletRequestWrapper.getRequest() method to access the wrapped
object, instead of storing it by yourself.
Best regards,

So the good news is that I got it to work by getting rid of any of the
methods that were overiding the implementation with a call to the child
request. Here's the links to the code that does NOT work : (I haven't
checked in the working code yet):

You have to provide the actual source code.
There is an example in the examples webapp that performs forwarding to
a JSP and it works,
\webapps\examples\WEB-INF\classes\ServletToJsp.java
