GAE上的Primefaces 3.5 JSF 2.1 ClassNotFoundException

我尝试将我的JSF 2.1 Webapp迁移到Google App引擎。GAE上的Primefaces 3.5 JSF 2.1 ClassNotFoundException

一切都运行在本地开发模式确定，部署也对GAE ok了，但是当我尝试访问任何网页，我得到HTTP代码500的日志文件表明，有一个ClassNotFoundException：

INFO: com.sun.faces.lifecycle.ELResolverInitPhaseListener populateFacesELResolverForJsp: JSF1027: [null] 
     The ELResolvers for JSF were not registered with the JSP container.

我已经试图部署相应的库jaxp-ri-1.4.jar，它没有任何作用。

一些更多的信息我的配置和第三方库：

- Mojarra JSF 2.1.12 
- Primefaces 3.5 
- Primefaces Extensions 
- Prettyfaces 3.3.3 
- Ebay Finding Api 
- STATE_SAVING_METHOD set to 'client' 
- i use EL 2.2 form jboss seam <context-param> 
    <param-name>com.sun.faces.expressionFactory</param-name> 
    <param-value>org.jboss.el.ExpressionFactoryImpl</param-value> 
    </context-param>

感谢您的帮助！

你看看这个：http://javadocs.wordpress.com/2009/10/17/mojarra-jsf-2-0-rc2-and-google-app-engine-sdk-1-2 -6 /＃more-242？ – 2013-04-25 19:42:26

是的，我检查了这一点。我已经实现了修改后的WebConfiguration.java。我认为lib文件夹中包含了旧文件。我重建所有内容并再次上传。同样的问题，但如果我访问该应用程序与网址：1.version.myapp.appspot.com - 它的工作！ – Sonic 2013-04-26 00:10:42

好吧，它不起作用。该页面现在呈现，但在任何ajax请求上，我收到了响应： class java.lang.NoClassDefFoundError<！[CDATA [无法初始化com.google.apphosting类.runtime.security.shared.stub.com.sun.org.apache.xerces.internal.dom.NodeImpl]]> – Sonic 2013-04-26 00:16:36

经过一番调试后，我发现eBay Finding API导致问题，因为它使用SOAP进行服务调用。不调用eBay Api，一切运行正常。

com.sun.org.apache.xerces.internal.dom.NodeImpl is a restricted Class

好像eBay的发现API是不是与谷歌App Engine的兼容，因为它使用JAX-WS。
