Websphere异常：找不到工厂：javax。面孔。上下文FacesContextFactory

Question

问题是，找不到工厂：javax。面孔。上下文FacesContextFactory，但在Websphere application server上。

我有一个Web应用程序，其中包含我自己的jsf impl、Mojarra 2.1.24和表达式语言2，但为此我遵循了IBM指南配置JavaServer Faces实现。如IBM所述，我创建了一个共享文件夹，其中放置了以下jar（我从WEB-INF/lib中删除了它）：

• el api。jar
• el impl。jar
• jsf api。jar
• jsf impl。jar
• jstl。震击器

然后我部署了webapp，并将共享库链接到webapp。

web.xml如下：

        <welcome-file>index.html</welcome-file>
    </welcome-file-list>

应用程序启动会产生以下异常：

Answer 1

我回答我自己的问题，因为我发现没有其他关于Webphere的问题，我想与社区分享我的发现。解决方案是将以下xml片段添加到web.xml：

<listener>
    <listener-class>com.sun.faces.config.ConfigureListener</listener-class>
</listener>

因为ServletContainerLaunalizerServlet 3.0功能似乎不适用于Webphere。
