10.16.3. WebServiceRef

The WebServiceRef annotation is used to declare a reference to a Web service. It follows the resource pattern exemplified by the javax.annotation.Resource annotation in JSR-250
There are two uses to the WebServiceRef annotation:
  1. To define a reference whose type is a generated service class. In this case, the type and value element will both refer to the generated service class type. Moreover, if the reference type can be inferred by the field or method declaration then the annotation is applied to the type, and value elements may have the default value (Object.class, that is). If the type cannot be inferred, then at least the type element must be present with a non-default value.
  2. To define a reference whose type is a SEI. In this case, the type element may be present with its default value if the type of the reference can be inferred from the annotated field and method declaration, but the value element must always be present and refer to a generated service class type (a subtype of javax.xml.ws.Service). The wsdlLocation element, if present, overrides theWSDL location information specified in the WebService annotation of the referenced generated service class. 
public class EJB3Client implements EJB3Remote
{
   @WebServiceRef
   public TestEndpointService service4;
   
   @WebServiceRef
   public TestEndpoint port3;
}
WebServiceRef Customization

In JBoss Enterprise Application Platform 5.0 we offer a number of overrides and extensions to the WebServiceRef annotation. These include:

  • define the port that should be used to resolve a container-managed port
  • define default Stub property settings for Stub objects
  • define the URL of a final WSDL document to be used
Example: 
<service-ref>
   <service-ref-name>OrganizationService</service-ref-name>
   <wsdl-override>file:/wsdlRepository/organization-service.wsdl</wsdl-override>
</service-ref>
.. 
<service-ref>
   <service-ref-name>OrganizationService</service-ref-name>
   <config-name>Secure Client Config</config-name>
   <config-file>META-INF/jbossws-client-config.xml</config-file>
   <handler-chain>META-INF/jbossws-client-handlers.xml</handler-chain>
</service-ref>
