Dependency injection of web services In my last blog, I wrote how JSR-250 defines the annotation for defining injection of resources. Java API for XML Web services 2.0 (JSR-224). You can use the javax.xml.ws.WebServiceRef annotation to define dependency and injection targets for a Web service.   Here is an example of a WebService annotation. The values for type and name are derived from the injection target:   @WebServiceRef public PurchaseOrderService poService;   This is much simpler than J2EE 1.4 where we first define the service-ref element in client's deployment descriptor and then do a JNDI lookup to get a reference to the service endpoint.   The injection will certainly simplify client-view of web services in Java EE 5.0 7:58:20 AM    comment []
