不能实例化侦听器guiceListner，ClassNotFoundException

我想在Google App Engine上使用Jersey创建一个RESTFul Web服务。我正在尝试添加Guice进行依赖注入。不能实例化侦听器guiceListner，ClassNotFoundException

我已addeded在web.xml

<listener> 
     <listener-class>com.archit.guice.GuiceListener</listener-class> 
    </listener>  

    <filter> 
     <filter-name>guiceFilter</filter-name> 
     <filter-class>com.google.inject.servlet.GuiceFilter</filter-class> 
    </filter> 
    <filter-mapping> 
     <filter-name>guiceFilter</filter-name> 
     <url-pattern>/*</url-pattern> 
    </filter-mapping>

下面我还定义在包com.archit.guice类GuiceListener。

在类GuiceListener的代码是：

public class GuiceListener extends GuiceServletContextListener { 

    private ServletContext servletContext = null; 

    @Override 
    public void contextInitialized(ServletContextEvent servletContextEvent) { 
     servletContext = servletContextEvent.getServletContext(); 

     super.contextInitialized(servletContextEvent); 
    } 


    @Override 
    protected Injector getInjector() { 
     return Guice.createInjector(new GuiceServletModule(), 
       new MainShiroWebModule(servletContext), ShiroWebModule.guiceFilterModule()); 
    } 
}

当我部署应用的AppEngine和调用任何REST API，我得到404错误和AppEngine上提供的错误日志：

即使我定义了类，ClassNotFoundException的原因可能是什么。我已尝试使用干净版本
