我正在使用JSF 2编写Web应用程序。我已经下载了mojarra-2.1.3-FCS-binary.zip和myfaces-core-assembly-2.1.3-bin.zip,并且每个库,我都是得到以下异常:

对于Mojarra,我在javax.faces.jar
文件夹中包含了WEB-INF/lib
,对于MyFaces,我用以下内容替换了jar:myfaces-api-2.1.3.jar,myfaces-bundle-2.1.3 .jar,myfaces-impl-2.1.3.jar。
我已经包含了jstl-api-1.2.jar以及jstl-impl-1.2.jar。
在这些罐子里发现了ApplicationFactory
。在这些情况下,JSF有什么问题?
我正在使用Tomcat 7来运行我的Web应用程序。
答案 0 :(得分:2)
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Tomcat/lib
,JRE/lib
,JRE/lib/ext
和/或Tomcat common lib中删除Mojarra JAR,最后删除除/WEB-INF/lib
以外的webapp运行时类路径中的所有位置。
