我有一个JSF webapp在Linux Tomcat7和Windows（Tomcat7和Tomcat8.0.24）中完美地工作。但是在Linux Tomcat8.0.32中，它失败并出现错误：
javax.faces.FacesException: /app/login/IndexLogin.jsp (line: 8, column: 0) Absolute Uri: http://java.sun.com/jsf/core can not resolve
org.apache.myfaces.context.servlet.ServletExternalContextImpl.dispatch(ServletExternalContextImpl.java:431)

我已经阅读过有关JSTL 1.1和1.2的内容，虽然我不知道如何检查我正在使用哪一个，但令我感到困惑的是，为什么在Windows中它起作用，在Linux中也是如此jar库，它没有？ ????
