I have set up RequestDispatcherProvider to redirect from OAuth 2.0 authorization service (implemented by AuthorizationCodeGrantService) to different JAX-RS service, both served by the same CXFServlet.
The problem is HttpServletRequestFilter in RequestDispatcherProvider do not returns correct RequestURI path - the context root path of the web application is missing.
RequestURI is used then by HttpUtils to built JAX-RS service matching path and since the request URI is not correct, the service is not found.
Configuration of request dispatcher is the following:
"rest" is the name of the application (context root where the application is deployed)
"/*" is CXFServlet's URL pattern
"/oauth2" is the jaxrs:server address
"/implicitauthorize" is the path of the mentioned JAX-RS service where the redirect should go
