Tomcat5 - conflicting libraries

The following error occured while trying to deploy a .ear
with scoped classloading on JB3.2.4RC1.
This ear-file contained an older version of the jakarta-
digester than the one in jbossweb-tomcat50.sar
directory.

When I removed the servlet-api.jar and jsp-api.jar from
jbossweb-tomcat50.sar, the exception disappeared.
(These api's are still in the server lib folder named as
javax.servlet.jar and javax.servlet.jsp.jar)
