Spring MVC Portlet和Weblogic Portal

Question

我试图创建一个Spring MVC Portlet（版本3.0.0）在Weblogic Portal（10.3.2）中进行部署，但在进入门户页面时出现以下错误已经把我的portlet：

The portlet "helloWorld" is not available. The portlet class org.springframework.web.portlet.DispatcherPortlet is not found. javax.portlet.UnavailableException: The portlet "helloWorld" is not available. The portlet class org.springframework.web.portlet.DispatcherPortlet is not found.

是否有可能在Weblogic Portal中使用Spring Portlet MVC还是我在这里浪费我的时间？上面看起来有点像ClassNotFoundException，但是我在Portlet的WEB-INF/lib文件夹中有所有需要的弹簧罐，所以我不确定它可能意味着什么。

任何帮助将不胜感激。

貌似有我的portlet.xml文件中的一个问题，我有以下几点：

<portlet> 
    <portlet-name>helloWorld</portlet-name> 
    <portlet-class> 
    org.springframework.web.portlet.DispatcherPortlet     
    </portlet-class> 
... 
</portlet> 

有在标签之间的一些标签，当我删除了空白看起来像这样：

<portlet> 
    <portlet-name>helloWorld</portlet-name> 
    <portlet-class>org.springframework.web.portlet.DispatcherPortlet</portlet-class> 
... 
</portlet> 

它的工作！什么是恼人的问题，我假设的portlet容器将能够读取类名称和去除任何空格，但显然不是:(
