That makes it more difficult :-)
I checked my downloads of myfaces-api and myfaces-impl and tomahawk for
duplications - it was a long shot - but as expected no duplicates.
Try this - take out the myfaces-impl jar from the "WEB-INF/lib" because that
is where the duplicate entry is. If it really is duplicate it should load
or give you some other error because the JSF version will be wrong. But the
key is that the duplicate entry will be gone. If that happens then you know
there is another entry somewhere.
I've also had times when I forgot that I put myfaces jars into a shared lib
directory. Just for sanity - I would check that too.
Hope that helps,

Thank you for your answers.
I've put the suggested by Mike
org.apache.myfaces.CHECK_EXTENSIONS_FILTERcontext-param tag in
the web.xml and it eliminated the previous errror, but introduced a
similar one on another component on the page (see below).
Jay, WebLogic version we are using is 8.1 and it doesn't include JSF for
sure (it didn't exist at the time it was released), I only have the jars I
mentioned before in the app, and I don't mix RI and myfaces, just myfaces
are used.
What we have is this stanza in weblogic.xml:
</jsp-descriptor>
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
and here are all the jars we have in web-inf/lib:

*Subject:* Re: duplicate class definition exception
Hello,
I have gotten this exception when I have multiple tomahawk jars, or jsf
jars (RI or myfaces) in the classpath.
I originally got this issue when using jboss and a war file that packaged
the MyFaces jars. The classloader is basically finding two instances of the
class, and not able to determine which to use. This may also be a check in
JSF itself - I'm not sure.
I would check if web logic packages a JSF implementation, If so the only
way I found to get around it was to update the rev in JBoss to the one I
wanted and not include my own in my war. If this is not an option I think
you'll have to remove the jsf jars from web logic.
Hope this helps,
Jay
