[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
