Accessing JAX-RS MessageContext in a filter
Hi All,
I am trying to get access to MessageContext in a filter (that implements RequestHandler interface)
by doing this:
private MessageContext mc;
@Context
public void setMessageContext(MessageContext msgC) {
mc=msgC;
}
Because I saw in the list that a bug was filed about if @Context was used on a fields like this:
@Context
private MessageContext mc;
But even using Context on the setter does not work. Do I need to do any wiring in the Spring file when I use the
Setter like above?
Is @Context suppose to work with filters ( I thought they should as filters are like providers)?
What I am trying to do using Context is set a Map that I created in the filter after processing http headers
And I want to access that Map in some other class later in the code and would like to use @Context to get the map.
Is this a good use of @Context? Or can I do this in any other way?
Thanks a lot for any help.

RE: HELP! Was:RE: Accessing JAX-RS MessageContext in a filter
Posted by "Pydipati, Karuna" <kp...@stubhub.com>.
I sent this mail to my team sometime back. Hope, this may be helpful. I
am using it in Impl class. Not in filter.
================
In the REST world, in order to get/set Cookie information or any other
information that is stored in httpRequest, here is the simple and
elegant way.
1. DO NOT add anything in web service interface. Not even in method
signature (Common mistake is that developers try to add arguments to get
Cookie information)
2. Have a filed MessageContext in Impl class and annotate it with
@Context
3. Try to access it in any method. This is thread safe interface because
it implements ThreadLocalMessageContext
4. You can access all the below mentioned information from
MessageContext
UriInfo,
SecurityContext,
HttpHeaders,
Providers,
Request,
ContextResolver,
Servlet types (HttpServletRequest, HttpServletResponse,
ServletContext, ServletConfig)
Here is example for usage of MessageContext
public class SomeWebServiceImpl implements SomeWebServiceService {
@Context
MessageContext resp;
public SomeApiResponse someMethod(SomeRequest someRequest) {
AuthenticatedSession authenticatedSession = null;
SomeApiResponse someApiResponse = new SomeApiResponse();
try {
HttpServletResponse httpServletResponse =
resp.getHttpServletResponse().addCookie(STUB_SESS);
HttpHeaders httpheaders = resp.getHttpHeaders();
HttpServletRequest httpServletRequest =
resp.getHttpServletRequest();
ServletConfig servletConfig = resp.getServletConfig();
ServletContext servletContext = resp.getServletContext();
UriInfo uriInfo = resp.getUriInfo();
Providers providers = resp.getProviders();
} catch ( Exception e) {
log.error(" Exception: " + e);
}
return someApiResponses;
}
public interface SomeWebServiceService {
@Path("identified")
@POST
public SomeApiResponse someMethod(SomeRequest someRequest);
}
====================

Hi cxf group,
Could you please respond to my question below? The main question is if
Context get/set is allowed in JAX-RS filters?
I need an answer urgently as I need to deliver some code by tomorrow And
I need to figure out whether to implement a work around or there is
Something simple I am missing and have overlooked in using JAX-RS CXF?
Thanks very much for your help in the past. Hope to hear from Someone
soon.
Sadhana

Hi Sadhana
Unfortunatley, it will only be possible to inject contexts in filters starting from 2.2.4.
However, as a workaround, you can get most of what you can get from a MessageContext using a provided Message instance
here's some examples :
HttpServletRequest request = (HttpServletRequest)message.get(AbstractHttpDestination.HTTP_REQUEST)
HttpHeaders headers = new HttpHeadersImpl(message);
UriInfo ui = new UriInfoImpl(m, null);
// etc...
let me know please if you need more info,
cheers, Sergey
