When I am developing a JSF project in Tomcat 7, the server keep arguing this class not found. May I know which jar am I missing?
Caused by: java.lang.ClassNotFoundException: javax.el.CompositeELResolver
I have already put this jar in the Tomcat lib folder:
Beside this, I also have servlet-api-2.5.jar and servlet-api.jar, not sure which one is currently using by Tomcat 7.
Tomcat 7 is a Servlet 3.0 container. It already comes along with JSP/Servlet/EL libraries by itself. You can find them all in
/libfolder of the default (and untouched) Tomcat installation.You should not add libraries of a different servletcontainer make/version in there. You should only add libraries which are not already provided by Tomcat itself. So the following statements
are not a good indication that you understood it. You should remove all Servlet API libraries which you explicitly added yourself. This would only conflict with Tomcat’s own ones and result in this kind of classpath troubles.
