For my Seam app, I use Hibernate Tools (hbm2java) via 'seam generate-entities' command to reverse engineer my tables.

I am using sqljdbc.jar (MSSQL 2005 RDBMS) version 1.2.

I noticed that the following line is always omitted in the entity class that is generated for a table that has an identity column as PK (i.e. auto-generated/incremented PK int):



So I end up with an entity class like this:



Is there a way I can instruct hbm2java to include the @GenerateValue annotation in the entity class which is based on table with identity PK? If yes, how?

Currently, I must add this code manually...

So I found a partial answer in Bauer/King JPA/Hibernate book.

In section 2.3.2 Customizing reverse engineering, there is an example foo.reveng.xml file.

For a particular table, you can specify the Hibernate identifier generator as follows:



But how can you configure this xml file such that it uses IDENTITY column for @GeneratedValue for all tables that will be reverse engineered?

There are not a lot of example on customizing the revengr. Perhaps it's best to view the revengr dtd???
