Hi wolf and Bill (nice talk at JavaOne btw): As per section 4.5.1 in the ejb-3_0-fr-spec-ejbcore entitled, "Stateless Session Bean State Diagram", see Figure 6. And I quote from the spec: "When the container no longer needs the instance (usually when the container wants to reducethe number of instances in the method-ready pool), the container invokes the PreDestroy lifecycle callback interceptor methods for it, if any. This ends the life of the stateless session bean instance." [pg 85] I would think undeployment would definitely fit under that statement. Bill, with all due respect, I shouldn't have to plug anything in...that's your job! :D! Also, why aren't naming contexts removed from JNDI space still? Is that expected behavior? -aps View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3962481#...
