Wrapped is an implementation detail from the Java domain. Neither in the abstract contract (for instance, wsdl+schema) nor at the SOAP message level is a wrapped endpoint recognizable. A wrapped endpoint or client uses the individual document payload properties. Wrapped is the default and does not have to be declared explicitly.

@WebService
public class DocWrappedServiceImpl
{
   @WebMethod
   @RequestWrapper (className="org.somepackage.SubmitPO")
   @ResponseWrapper (className="org.somepackage.SubmitPOResponse")
   public String submitPO(String product, int quantity)
   {
   ...
   }
}
