I've got the same probleme under Tomcat, it's caused
by tomcat class loader when yours actions
(baepp.Authentication) are not loaded in the class
loader witch load struts classes.
I don't know JRun, but under tomcat, we must have
struts.jar in every webapp:
[WEBAPP]/WEB-INF/lib/struts.jar
[WEBAPP]/WEB-INF/classes/baepp/Authentication.class
