 */

@WebService(endpointInterface = "net.spring.webservice2.GreetingService",serviceName = "aaa",targetNamespace = "sdjfsdl")
public class GreetingServiceImpl implements GreetingService {

	@Resource
	private WebServiceContext webServiceContext;

	@Override
	public String greeting(String userName) {

		HttpServletRequest request = (HttpServletRequest) webServiceContext
				.getMessageContext().get(MessageContext.SERVLET_REQUEST);
