Need help understanding a struts error

[Mark Tobin]

[com.opensymphony.xwork2.conversion.impl.InstantiatingNullHandler] Entering nullPropertyValue [target=[com.myapp.novo.web.LoginAction@61b0d990, com.opensymphony.xwork2.DefaultTextProvider@4afbf04a], property=__sitemesh__decorator].

This application works in tomcat but in jboss I get the above error when trying to log in.

my struts.jars are in WEB-INF/lib

mu struts.xml an validators.xml are in WEB-INF/classes,

is there anything I need to add to make struts work in JBoss a struts-jboss xml file

Ignore this post, found the error a service is set up in tomcat but not set in jboss
