Java EE (Java Enterprise Edition) General Discussion

Hi all,

I am a newbie at JSF.
SITUATION:: I have a project already running with Java EE 1.4 and jsf 1.1.
PROBLEM:: I want to migrate the project to Java EE 1.5 and jsf 1.2.
SOLUTION:: ??

I tried using the converter plugin (http://blogs.sun.com/winston/entry/vwpprojectconverter) and managed to get rid of some bugging errors.
But i am still stuck on one exception::

SEVERE: Exception sending context initialized event to listener instance of class
com.sun.faces.config.ConfigureListener
java.lang.NoClassDefFoundError: javax/faces/application/StateManagerWrapper

and

SEVERE: Error configuring application listener of class com.sun.faces.extensions.avatar.event.DynaFacesContextListener
java.lang.NoClassDefFoundError: javax/faces/FacesException

I just cant understand why this error is coming.

What i have ALREADY tried::
1. copying the jsf-api.jar in tomcat lib.
2. jsf-extensions-dynamic-faces-0.1.jar to tomcat lib.

Please give me any suggestions or solutions if any....
