在GAE上的Primefaces 3.5 JSF 2.1 ClassNotFoundException

Question

我嘗試將JSF 2.1 Webapp遷移到Google App引擎。

一切都可以在本地開發人員模式下正常運行，在GAE上也可以正常部署，但是當我嘗試訪問任何頁面時，都會得到HTTP Code500。日志文件顯示存在ClassNotFoundException：

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

我已經嘗試部署相應的庫jaxp-ri-1.4.jar，但沒有任何效果。

有關我的配置和第三方庫的更多信息：

- 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>

謝謝你的幫助！

Answer 1

經過一些調試后，我發現eBay Finding API導致了問題，因為它使用SOAP進行服務調用。 無需致電eBay Api，一切運行正常。

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

似乎eBay查找API與Google App Engine不兼容，因為它使用JAX-WS。
