Actually, I've confirmed ejb3 file did contain stuff. with jar -xf Also tried using *.* for jar command to pick up *.class & *.java. Also noticed status messages for JBoss 18:49:15,718 INFO [JmxKernelAbstraction] installing MBean: jboss.j2ee:jar=SimpleSessionApp.ejb3,name=SimpleSessionBean, service=EJB3 with dependencies: 18:49:15,859 INFO [EJBContainer] STARTED EJB: beans.SimpleSessionBean ejbName: SimpleSessionBean 18:49:15,890 INFO [EJB3Deployer] Deployed: file:/C:/apps/jboss-4.2.2.GA/server/all/deploy/SimpleSessionApp.ejb3 18:49:15,921 INFO [TomcatDeployer] deploy, ctxPath=/jmx-console, warUrl=.../deploy/jmx-console.war/ So is there some problem that JBoss has with doing JNDI lookups on Interface SimpleSession? If I was to do bind to SimpleSessionBean and cast this to Interface I think I might solve problem.. But it begs the question why is the interface not available to bind to?
