FaqDesktopDatabaseIdentityColumn

How do I use an IDENTITY column in a Java Desktop Application?

If you get an error when trying to save a new record in a Java Desktop Application created with the Database Application shell on a database that has an IDENTITY column, it might be because the New Project wizard did not generate the correct annotation in the entity class.

To fix:

1. Open the entity class for the table that has the identity column.
2. Add the following annotation below the line with the @ID annotation:

@GeneratedValue(strategy=GenerationType.IDENTITY)
