Thanks to all who replied. After much toiling, I got the example working
under weblogic. As Anshum indicated, SP6 was necessary. However, SP5 may
have worked as well, according to an article that I read.
I also used the weblogic classloader "hack" descibed at:
http://archive.covalent.net/jakarta/struts-user/2000/10/0009.xml
Thanks again,
Jeff

Download and install Service Pack for WL5.1. That should get rid of this
problem.
