With JAX-WS 2.0, I don't think theres a "clean" way to do this. You
could do something like:
Object getAnnotation(String classOfAnnotation);
and on the client side, provide a utility like:
public T getAnnotation(Class<T> classOfAnnotation) {
return classOfAnnotation.cast(
service.getAnnotation(classOfAnnotation.getName());
);
}
That kind of sucks though. With JAX-WS 2.1, you MIGHT be able to use
the @XmlJavaTypeAdapter annotation on the Class parameter to map it to a
String in the wsdl to do much of that automatically. To do that with
2.0 would require you to use wrapped doc/lit and to write
a "GetAnnotationRequest" class that hadd the @XmlJavaTypeAdapter on
the "classOfAnnotation" property.
The other issue you will run into is getting all the possible types of
<T> into the JAXB contexts so that they can be marshalled. The
jaxb.index files can come in there as well as the spring configurations
for the JAXB databindings and such.
