I know the more accepted pattern is to not have logic into the entity. However I am performing the migration of an application from EJB2 to EJB3 where there is logic into the entities. In my old entity bean (not session bean), I have code that call getCallerPrincipal from the EntityContext. I have tried, using @Resource, to inject EntityContext but I got a null value. Is there a way to access the callerPrincipal from entity in EJB3. Thank you very much for your help, An Phong Do View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4203647#...
