The interesting fact is that deployment works fine...i.e. my EJB is successfully deployed with no errors which means it jBoss Application Server successfully found the DataSource java:/jdbc/myDS but when I try to access the same in my auto-start code it fails! Also just to add here, if I directly lookup JNDI (which is not desired because it won't work on WebSphere, WebLogic) it finds the resource OK.
I have done this many times with other JCA resources and never faced a problem, I think I might have missed something which I am not able to pin point! Can you please help?
