For Mojarra, I included javax.faces.jarin WEB-INF/libfolder, and for MyFaces, I replace the jar with the following: myfaces-api-2.1.3.jar, myfaces-bundle-2.1.3.jar, myfaces-impl-2.1.3.jar.
对于 Mojarra，我包含javax.faces.jar在WEB-INF/lib文件夹中，对于 MyFaces，我将 jar 替换为以下内容：myfaces-api-2.1.3.jar、myfaces-bundle-2.1.3.jar、myfaces-impl-2.1.3.jar。
I've included jstl-api-1.2.jar as well as jstl-impl-1.2.jar.
我已经包含了 jstl-api-1.2.jar 和 jstl-impl-1.2.jar。
And ApplicationFactoryis found in those jars. What is the issue with JSF in these instances?
并且ApplicationFactory是在那些罐子里找到的。在这些情况下，JSF 有什么问题？

This exception suggests that the Mojarra API was been loaded from the server-dedicated classloader while the Mojarra/MyFaces impl is loaded from the webapp-dedicated classloader. Remove the Mojarra JARs from Tomcat/lib, JRE/lib, JRE/lib/extand/or Tomcat common lib and eventually all places in webapp's runtime classpath other than /WEB-INF/lib.
此异常表明 Mojarra API 是从服务器专用的类加载器加载的，而 Mojarra/MyFaces impl 是从 webapp 专用的类加载器加载的。从取出钻嘴鱼科的JAR Tomcat/lib，JRE/lib，JRE/lib/ext和/或Tomcat共同lib和最终所有的地方比其他Web应用程序的运行时类路径/WEB-INF/lib。
