How does the id get generated? Say I have a simple entity bean with 2 attributes id and desc. Attribute id is tagged with @Id @GeneratedValue(strategy=GenerationType.AUTO). Can I create a new object of this class with just the desc and let Hibernate create the id? In the database end, do I create the table for this entity with column id declared as bigint? Thanks in advance for your help. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4024395#...
