Java EE (Java Enterprise Edition) General Discussion

Hi,
I get the following error when deploying my webapp to Tomcat 4.0:

[Thu Dec 18 12:03:16 EST 2003] stdout: StandardWrapper[DeployApp:Faces Servlet]: Marking servlet Faces Servlet as unavailable
[Thu Dec 18 12:03:16 EST 2003] stdout: StandardContext[DeployApp]: Servlet /BULDeployApp threw load() exception: javax.servlet.ServletException: Wrapper cannot find servlet class javax.faces.webapp.FacesServlet or a class it depends on
[Thu Dec 18 12:03:16 EST 2003] stdout: javax.servlet.ServletException: Wrapper cannot find servlet class javax.faces.webapp.FacesServlet or a class it depends on

The jsf-ri.jar is copied in $tomcat_home/common/lib (to solve the ConfigListener error) and following libraries are a part of web-inf/lib:
commons-beanutils.jar, commons-collections.jar, commons-digester.jar, commons-logging.jar, jsf-api.jar, jstl.jar, standard.jar.


Please help.
