Just a heads up for everyone out there. I needed to make the following changes to guvnor's POM in order to get the webapp to work properly on Tomcat. I would imagine some of these issues would appear on JBoss also but have not tried.
1. Changed seam from 2.1.0.BETA1 to 2.1.0-SNAPSHOT to prevent classloader problem
POM Changes
<dependency>
<groupId>org.jboss.seam</groupId>
<artifactId>jboss-seam-remoting</artifactId>
<version>2.1.0-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>org.jboss.seam</groupId>
<artifactId>jboss-seam</artifactId>
<version>2.1.0-SNAPSHOT</version>
</dependency>
