You can package the interceptor in a jar in .ear/lib and then have a EJB within some other jar in the .ear and use @Interceptors to point to that interceptor class.
Sorry I went to fast here...
I dont want to use @Interceptors(Interceptorclass.class) for binding the Interceptor. I want to use CDI's @InterceptorBinding. Is this possible with an Ear wide Interceptor?
