无法运行GWT示例

我正在尝试运行GWT示例StockWatcher。我用户webAppCreator按照Google教程中的所有说明获取eclipse的progect。然后，将我的项目导入Eclipse，在项目属性中设置“使用Google Web Toolkit”复选框，然后单击调试为 - > Web应用程序。然后我得到无法运行GWT示例

这里是我的的web.xml文件：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

    <!-- Servlets --> 
    <servlet> 
    <servlet-name>greetServlet</servlet-name> 
    <servlet-class>com.company.gwt.stockwatcher.server.GreetingServiceImpl</servlet-class> 
    </servlet> 

    <servlet-mapping> 
    <servlet-name>greetServlet</servlet-name> 
    <url-pattern>/stockwatcher/greet</url-pattern> 
    </servlet-mapping> 

    <!-- Default page to serve --> 
    <welcome-file-list> 
    <welcome-file>StockWatcher.html</welcome-file> 
    </welcome-file-list> 

</web-app>

这里是StockWatcher.gwt.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<module rename-to='stockwatcher'> 
    <inherits name='com.google.gwt.user.User'/> 

    <inherits name='com.google.gwt.user.theme.clean.Clean'/> 

    <entry-point class='com.company.gwt.stockwatcher.client.StockWatcher'/> 

    <source path='client'/> 
    <source path='shared'/> 

</module>

重复，即使这个问题我从教程页面下载项目。我该如何解决这个问题？

UPD：奇怪，但是当我试图再次启动它（无变化）我有“的问题发生”窗口：
