    Method Overloading and SOAP Annotations

    Narayanan Raghavan Newbie

      I have my HelloWorld EJB3 service with 3 overloaded methods and corresponding SOAP Annotations.

      Hello World Impl Code:

      public class SomeServiceBean implements SomeService {
      
       @WebMethod
       @WebResult(name="someData")
       public string SomeMethod ( @WebParam(name="somedaylong") long X,
       @WebParam(name="somedaylong") long Y,
       @WebParam(name="somemonth") string Z) {
      ....
      }
      
       @WebMethod
       @WebResult(name="someData")
       public string SomeMethod ( @WebParam(name="somedayint") int X,
       @WebParam(name="someweekint") int Y,
       @WebParam(name="somemonth") string Z) {
      ....
      }
      
      
       @WebMethod
       @WebResult(name="someData")
       public string SomeMethod ( @WebParam(name="somedaylong") long X,
       @WebParam(name="someweekint") int Y,
       @WebParam(name="somemonth") string Z) {
      ....
      }
      }
      
      


      Per the WSDL Spec, the combination of method name and in/out parameter name should be unique as in this case i.e.,

      [SomeMethod, somedaylong, somedaylong, somemonth]
      [SomeMethod, somedayint, somedayint, somemonth]
      [SomeMethod, somedaylong, somedayint, somemonth]

      When I deploy this service in my JBoss 4.2.1 GA container i get the following error message:
