Java ClassCastException:无法使用Tomcat 8将FaceSinializer强制转换为ServletContainerInitializer

在我将javaee-web-api-7.0.jar添加到我的JSF项目后，它会停止工作，并出现以下错误：

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

服务器ApacheTomcat8中没有这个库，我也没有使用maven。 在这里尝试了一些答案，但没有任何帮助

thx

全堆栈跟踪

因为我使用的是NetBeans 8，而我不能将TomEE与JEE Web 7一起使用，所以我不得不将javax.ejb放在{tomcat home}/lib中

不幸的是，netbeans仍然无法识别它，因此我更新了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lib并使用它进行构建，我不需要将其包含在项目libs中

java ee web api中唯一需要的是注释和ejb，现在我正在手动加载它们。

javaee-web-api-7.0.jar是否包含javax.servlet.*类？如果是这样，那么将其放入web应用程序是不合法的。如果你想在Tomcat中使用JavaEE，为什么不使用TomEE并把它从盒子里拿出来呢？我会尝试一下，谢谢你的想法：希望它能工作。
