Answer 1

That will work only when all the supporting classes are placed inside the WEB-INF/lib directory only in form of Jar files.
If any one of the Class is being loaded from outside of the WEB-INF/lib jars then you will definately face this issue......
Example:
Suppose "com.sun.faces.el.impl.parser.* " classes are present in some other Jar file outside WEB-INF/lib but rest of the JSF Jars and Parser Jars are present inside the WEB-INF/lib directory ..in that case you will see this kind of issue Because the JSF config Parser will change according to the version of JSF and WLS also provides some supporting Jars in "modules/" or "server/lib" or in "common/lib" directories.
