无法调用rest cxf服务

我是RESTful服务的新手，我按照教程here .

我的部署描述符web.xml

<?xml version="1.0"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">

   </servlet-mapping>
</web-app>

cxf.xml描述符：

<beans xmlns:jaxrs="http://cxf.apache.org/jaxrs"   
       xmlns:util="http://www.springframework.org/schema/util"          
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      </entry>
    </jaxrs:extensionMappings>
  </jaxrs:server>
  <bean class="com.example.rest.OrderInfoImpl" id="order"></bean>
</beans>

我的休息服务 Interface OrderInfo.java：

package com.example.rest;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

@Path("/Order/")
public interface OrderInfo {

  @GET
  @Produces("application/xml")
  @Path("{orderId}")
  public Order getOrder(@PathParam("orderId") int officeId);

  @GET
  @Produces("application/xml")
  @Path("All")
  public OrderList getAllOrders();

}

实现OrderInfoImpl.java .

当我尝试运行localhost：8080 / RestDemo / services？_ wadl，localhost：8080 / RestDemo / services / order / 1我得到 404 Error .
