The examples are tested on Tomcat 6.0. For Tomcat 5.5, I believe that you need to have the Sun EL JAR (el-api.jar)on the classpath.
Thanks Michael that worked. What I am trying to do is use seam purely as a web frontend framework without using any of its persistence related capabilities. I have gotten this to work with all the config info in place. Now what I need to do is get rid of all the redundant persitence/jta etc libraries. Would you happen to know what those are besides a trial an error process of removing libraries and checking if the app works or blows up?
