I am trying to run Seam 2.1.0 on a WAS 6.1.0.15 server.  I have run into many classpath issues with the JSF implementation and other needed JARs, all which I have resolved so far.  Now I am getting this error when trying to run the 'Helloworld' example from the book 'JBoss Seam, Simplicity and Power ....'.
