使用Apache Axis2发布Web服务出错，求大神指点！在线等！

[大风歌1]

在Eclipse中配置了tomcat 跟 axis2 ， 在浏览器地址栏中输入如下的URL：
http://localhost:8080/axis2/ 显示Axis2安装成功。

做一个简单的例子：
public class SimpleService {
public String getGreeting(String name) {
return "你好 " + name;
}
public int getPrice() {
return new java.util.Random().nextInt(1000);
}
}

编译SimpleService类后，将SimpleService.class文件放到<Tomcat安装目录>\webapps\axis2\WEB-INF\pojo目录中（如果没有pojo目录，则建立该目录）。现在我们已经成功将SimpleService类发布成了WebService。在浏览器地址栏中输入如下的URL：
http://localhost:8080/axis2/services/listServices

却显示：
Faulty Services

C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0\webapps\axis2\WEB-INF\pojo\SimpleService.class
