i'm having the same issue...the UserTransaction bean initialzation tries to find TransactionManager in a new InitialContext(). it doesnt supply its own properties to the InitialContext(), so the default ones (in my case, the apache tomcat ones) are being picked up. how do i tell tomcat to launch w/ the jboss jndi properties are the default? i tried putting the jndi.properties in my webapp's WEB-INF/lib and WEB-INF/classes, and in tomcat's server\classes dir, to no avail. where does it go?
