OK, I got a Java 5 Proxy to be invoked thru CXF. I had to:
* Declare an interface for the service class
* Annotate interface with @WebService
* Annotate interface method with @WebMethod, @WebResult, and all the @Web
Param annotations
* Declare a service class that implements the interface
* Annotate class with @WebService. Set the attributes for serviceName and
endpointInterface
* there is _no_ need to add @WebMethod, @WebResult, or @WebParam to the
class
* In the Spring XML: Proxy your class
Thanks,
Hamlet
