無法運行GWT示例

我正在嘗試運行GWT示例StockWatcher。我用戶webAppCreator按照Google教程中的所有說明獲取eclipse的progect。然後，將我的項目導入Eclipse，在項目屬性中設置「使用Google Web Toolkit」複選框，然後單擊調試爲 - > Web應用程序。然後我得到無法運行GWT示例

這裏是我的的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

    version="2.5"

    <!-- 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>

這裏是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>

重複，即使這個問題我從教程頁面下載項目。我該如何解決這個問題？

UPD：奇怪，但是當我試圖再次啓動它（無變化）我有「的問題發生」窗口：
