[jboss-user] [EJB 3.0] - Re: EJB QL/ JPQL and search for inheritance

Hi Andy (and everybody else), thank you for fast reply. That works well and is a first step torwards a solution. But I still need access to properties of the subclasses in the collection. Speaking in plain java it would be condition like this: | if (tag instanceof PlaceMark && ((PlaceMark)tag).getPoint().getX() == 0.0d) | So is it possible to do something like a cast? I read through Mr Monsons-Haefels and Mr Brukes book an found nothing useful. Regards --- Joachim View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3991618#...
