The Jersey runtime catches the WebApplicationException, so it is never
propagated to the servlet container, and so it cannot be trapped by an
error page.
If WebApplicationException was re-thrown the status set by the Jersey
servlet, from the info in WebApplicationException, would be ignored and
would result in a 500 status code as far as i can tell.
It appears error page support like the following:
<error-page>
<error-code>404</error-code>
<location>/notFound.jsp</location>
</error-page>
only works if a request as not been dispatched to a servlet i.e. it does
not appear to work when a request is dispatched to a servlet that sets
the status code and returns without throwing an exception. So in that
case i don't know how one can return a page for 415 (Unsupported Media
Type).
The same behavior occurs for Tomcat 6.0.14 and GF v2.
I am not that familiar with this area of Web apps but anyway all this
does indicate we need some improvements. Maybe we need something
311/Jersey specific for handling error pages?

A stable version of 0.5 ea will be out this Friday. I recommend you
switch to that, although you will still observe the same error behavior
as you observe for 0.4.
