java.lang.ClassNotFoundException: com.sun.faces.config.ConfigureListener when using MyFaces with WASCE/Geronimo

Question

I am trying to create a simple JSF web application using MyFaces v 2.1 with WebSphere Application Server Community Edition v3.0.0.1 and Eclipse Juno but when I try to run the application the following error is returned

    java.lang.ClassNotFoundException: com.sun.faces.config.ConfigureListener

Presumably the error is occurring because the MyFaces jar files are not in the class path however I cannot figure out where I’m going wrong as the build path in Eclipse contains the required jars. I’ve also tried copying the jar files into the WEB-INF/lib directory but to no avail.

The screenshot below shows the project structure along with the libraries.

Is there something specific I need to do either in Eclipse or WASCE to include the jar files or does the problem lie elsewhere?

The missing class is part of Mojarra, which is actually the competitor of MyFaces.

You shouldn't need that class at all when using MyFaces. This exception can have the following possible causes:

• There's a manually definied <listener> entry in webapp's web.xml or the web-fragment.xml of any of the deployed JARs in /WEB-INF/lib which references this Mojarra-specific listener class.

• There's somewhere a loose Mojarra .tld file in the classpath (very unlikely, who would ever extract a JAR file and put its loose contents in the classpath?). TLD files get autoinitialized and can contain a <listener> entry which can trigger autoregistration of a ServletContextListener implementation (such as the Mojarra ConfigureListener).

Those conflicts can be fixed by just removing it.
