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 On 1/25/07, Mike Kienenberger <[EMAIL PROTECTED]> wrote:
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.
