ClassCastException：无法使用 Tomcat 8 将 FacesInitializer 转换为 ServletContainerInitializer

Question

在我将 javaee-web-api-7.0.jar 添加到我的 JSF 项目后，它停止工作并出现错误：

org.apache.catalina.startup.ContextConfig.processServletContainerInitializers Failed to process JAR found at URL [/RegaloCE] for ServletContainerInitializers for context with name [{1}]

java.io.IOException: java.lang.ClassCastException: Cannot cast com.sun.faces.config.FacesInitializer to javax.servlet.ServletContainerInitializer

好吧，服务器（apache tomcat 8）没有这个库，我没有使用 maven。
从这里（stackoverflow）尝试了一些答案，但没有任何帮助..

谢谢

完整的堆栈跟踪

好吧，因为我使用的是 NetBeans 8，而我无法将 TomEE 与 JEE Web 7 一起使用，我不得不将 javax.ejb 放入 {tomcat-home}/lib..

不幸的是 netbeans 仍然无法识别它，所以我更新了 nbproject 文件夹中的 project.properties 并将 ${j2ee.server.home}/lib/javax.ejb-api-3.2.jar 添加到 j2ee.platform.classpath 属性中。..

现在 netbeans 可以识别该库并使用它进行构建，我不需要将其包含在项目库中..

（我在 java ee web api 中唯一需要的是注解和 ejb，现在我手动加载它们..
