Question

美好的一天，

现在我正在尝试将我当前正在运行的应用程序（Primefaces + EJB + JPA + Glassfish 4.0）迁移到WAS 8.5。我尝试使用mojarra来使Primefaces工作。我以为我已经成功了但是我在启动期间在SystemOut.log中的事件报告中偶然发现了这个例外：

FFDC异常：java.lang.IllegalStateException SourceId：com.ibm.ws.webbeans.services.JCDIWebListener.contextInitialized（）ProbeId：104 Reporter：com.ibm.ws.webbeans.services.JCDIWebListener@fa0f39fa java.lang.IllegalStateException：与JCDI一起使用的不支持的JSF实现

当我尝试按下调用＃{navigationBean.login}的按钮时，我得到了这个例外：

javax.el.PropertyNotFoundException: /login.xhtml @45,111 action="#{navigationBean.login}": Target Unreachable, identifier 'navigationBean' resolved to null

进一步的研究表明（如果我错了，请纠正我），使用MyFaces JSF实现，WAS的CDI实现（Apache OpenWebBeans）效果最好（或仅适用于？）。所以我怀疑这是因为我使用的是Mojarra而不是MyFaces。所以我继续尝试尝试替换OpenWebBeans只是为了发现我无法将其更改为Weld CDI Implementation（这是Glassfish使用的）。

有关如何解决此问题的任何建议？我真的希望能够在websphere中使用primefaces。

更新：更新：我能够显示我的第一页（使用primeface + MyFaces的登录页面）。但是，当我点击带有EL表达式的第一个元素（＃{navigationBean.login}）指向@Named类NavigationBean时，我仍然得到

javax.el.PropertyNotFoundException: /login.xhtml @45,111 action="#{navigationBean.login}": Target Unreachable, identifier 'navigationBean' resolved to null

此外，我还看到了这个异常跟踪：

通过进一步的研究，我的假设是:(你们都可以纠正，以便引导我走上正确的道路） - Websphere中的Primefaces + MyFaces运行良好。但是如果我想实现一个依赖注入，我将不得不求助于使用@ManagedBean而不是@Named CDI实现（到目前为止更好）

但是，如果有人知道如何使@Named仍然使用primefaces，你可以展示如何或至少指出我所知道的可以提供帮助的资源。

非常感谢。

我已经解决了自己的问题。 Primefaces适用于

MyFaces2.0+CDI(OpenWebbeans)+WAS8.5

我所做的是在我的bin文件夹中包含Primefaces所有必需的依赖文件，并在我的web.xml中进行一些调整然后它工作正常。：）

这是我的web.xml的一部分：

Primefaces + MyFaces + CDI（OpenWebBeans）+ WAS 8.5
