Sorry for this leak, PeterJ. I have in mind this :) I use for developing WinXP with Java 1.5, of course I don't use 1.4.x for EJB3. I have tried today Java 6 for running but still had the same results - but on the forum I read that the correct version for running is only 1.5. Yes So first of all - I don't understand how the deployment process works in JBoss AS 5.0 beta 1. I put in folder deploy my EJB jars, wars,ears, my datasources - > nothing happened (in both server configuration - all and default). I suppose I have to turn on some services in config files, but I don't know exactly what and where? Second - (if you know) can I use in this version of Jboss AS @EJB annotation in servlets, etc?
