[jboss-user] [JBoss Seam] - How to use @Id @GeneratedValue(strategy=GenerationType.AUTO)

[tonylmai]

My apology for posting the following Persistent/Hibernate question on this board. I had posted it on the Persistent/Hibernate forum but found myself visit this forum more frequent than others.

The question is: How does an ID declared as @Id @GeneratedValue(strategy=GenerationType.AUTO) get generated?

Say I have a simple entity with 2 attributes id and message. I don't want to worry about generating an unique ID for this record so I think would like to declare attribute id with @Id @GeneratedValue(strategy=GenerationType.AUTO).

Can I create a new object of this class with just the message 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.
