Accessing the web service implementation class from an interceptor

[Lucas Madar]

I need to access the web service implementation class from an 
interceptor to see if it has a particular custom annotation on it. How 
do I find out the class of the service implementation from an 
interceptor? Since I only need to read the annotation from the class 
itself, in this case I don't need the instance, just the class.

However, in another case, I would like to be able to inject something 
into the class in an interceptor (this isn't as important, though). Is 
it possible to get access to the class instance as well?

Thanks,
