Hi all I have an entity in which I need to assign my own ID to its primary key, I put the code to extract the id and set it to the field in a PrePersist method, however, the ejb validates the entity before calling that callback method so the exception will be thrown my question is where should I put this code or how can I say the EJB not to validate before persisting! any comment would be of great help thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4147047#...
