I need to redirect to a jsp that is inside WEB-INF from a CXF/Jetty
started
server.
How can I redirect from inside a rest service to a jsp that is inside
WEB-INF/jsp?
I tried doing a simple servlet forward but it always use the app context
regardless of weather the path starts with '/' or not.
I also saw the documentation but in my case the jsp is not related at all
with any entity (it's a login page).
Assuming your work with CXF 2.7.7, then what you can do is to use JAX-RS
2.0 Pre-Matching ContainerRequestFilter which will block the request
with a ready Response, this Response would set a media type text/html
and set the 'marker' entity either an enum (ex, LOGIN_REQUIRED) or some
empty class like LoginRequired, using enums can be cheaper, and then
configure CXF RequestDispatcherProvider as suggested here:
http://cxf.apache.org/docs/jax-rs-redirection.html#JAX-RSRedirection-WithRequestDispatcherProvider,
check the example on configuring it with enums if you chose to work with
enums.
Note, setting a 'marker' entity in Response is needed because otherwise
RequestDispatcherProvider, being JAX-RS MessageBodyWriter, won't be
activated.
However you can avoid using RequestDispatcherProvider by doing something
like this in your custom ContainerRequestFilter (vaguely referred to in
http://cxf.apache.org/docs/jax-rs-redirection.html#JAX-RSRedirection-CustomRedirection):
1. inject "@Context HttpServletRequest request";
2.
PhaseInterceptorChain.getCurrentMessage().put(AbstractHTTPDestination.REQUEST_REDIRECTED,
true);
3. Use HttpServletRequest to get to RequestDispatcher and forward the
request to the chosen jsp resource
This will work fine too.
Finally, if you have CXFServlet using a wildcard url pattern, then you'd
need to further restrict it to ensure the above redirects do not get
captured by the same servlet
Which is described in more detail here
http://cxf.apache.org/docs/jax-rs-redirection.html#JAX-RSRedirection-WithCXFServlet

Thanks in advance.
