jsf - Websphere异常: could not find Factory: javax. faces.context.FacesContextFactory

Question

问题是无法找到Factory:javax.faces.context.FacesContextFactory，但位于Websphere 应用程序服务器上。

我有一个 Web 应用程序，它附带了我自己的 jsf impl、Mojarra 2.1.24 和表达式语言 2，但为此我遵循了 IBM 指南 Configuring JavaServer Faces implementation 。正如 IBM 所说，我创建了一个共享文件夹，在其中放置了以下 jar(我从 WEB-INF/lib 中删除了它):

• el-api.jar
• el-impl.jar
• jsf-api.jar
• jsf-impl.jar
• jSTL.jar

然后我部署了 Web 应用程序并将共享库链接到 Web 应用程序。

web.xml 如下:

应用程序启动产生以下异常:

Answer 1

我回答我自己的问题，因为我发现没有关于 Websphere 的其他问题，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 中:

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

因为 ServletContainerInitializer Servlet 3.0 功能似乎无法在 Websphere 上运行。
