Don't know for sure, but you can start by adding the web.xml
org.apache.myfaces.CHECK_EXTENSIONS_FILTER context-param to get rid of
the warning.
Typically if you have a duplicate class issue, it's because you have
two copies of the jar file, possibly with different versions, in your
path somewhere. I think the class in question is part of
myfaces-impl.jar. Make sure you don't have any old version jars like
myfaces-all or myfaces-shared in your path as well.

Hi,
We are trying to trace the root cause of the following run-time exception
which seems to be happening every time the server gets restarted and a link
in the application gets clicked. We use Weblogic 8.1 sp2 with the following
myFaces jars:
myfaces-api-1.1.4.jar
myfaces-impl-1.1.4.jar
tomahawk.jar-1.1.3.jar
Has anyone experiensed this error? Any suggestions on how to prevent it from
happening?
