How to configure Jax-WS with Spring 3 using annotations only?

Question

I failed to access the url http://localhost:8080/mn_webapp/CustomerService?wsdl

with this configuration below :

@Configuration
@ImportResource({ "classpath:META-INF/cxf/cxf.xml"})
public class ContextConfig extends SpringBootServletInitializer {   
    @Bean 
    public ServletRegistrationBean dispatcherServlet() {        
        return new ServletRegistrationBean(new CXFServlet(), "/*"); 
    } 
    @Autowired
    private Bus cxfBus;     
    @Bean 
    public EndpointImpl endpoint() { 
        EndpointImpl endpoint = new EndpointImpl(cxfBus, applicationContext.getBean(IWCustomerService.class) ); 
        endpoint.publish("/CustomerService"); 
        return endpoint; 
    }     
}

and the web.xml

  <context-param>
      <param-name>contextClass</param-name>
      <param-value>   
   org.springframework.web.context.support.AnnotationConfigWebApplicationContext
      </param-value>
  </context-param>
  <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>com.dev.core.init.ContextConfig</param-value>
  </context-param>        
  <listener>  
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
     </listener>    

it seems that dispatcherServlet() and endpoint() are never called?
