proper way to inject Context objects?

[Jeff Wang]

I'm running CXF 2.5.2 with Spring 3.1.1

I declare my beans via

@Service
public class FooImpl implements IFooService {
}

inside FooImpl, @Autowired fields work just fine.  However, @Context
UriInfo gave me a IllegalArgumentException for trying to set a $Proxy
to a UriInfo.  I then added a <aop:aspectj-autoproxy
proxy-target-class="true"/> to my spring file.  This worked (I think)
but a @Context mc gave a null pointer exception when I try to access
it.  adding setters and moving the @Context annotation to the setters
did not help.  heck,

        @Context
        public void setMc(org.apache.cxf.jaxrs.ext.MessageContext mc) {
                System.out.println("***mc is set");
                this.mc = mc;
        }

did not result in the println being executed.

Finally, when I put the @Context MessageContext mc as a method
parameter, the injection works fine.  Am I doing anything that's
unexpected with regard to MessageContext?

thanks
