Dropping the struts-example.war and struts-validator.war files into default/deploy of JBoss 3.0.3-Tomcat4.1.12 generate the following error (and other similar errors). Interestingly, doing the same with JBoss 3.0.0-Tomcat4.0.3 works just fine. Anyone know what has changed or what I may have configured incorrectly?
