Hibernate is a persistence layer for SQL databases. Many Derby users have reported both success and failure using it. This Wiki page hopes to bring together everyone's experience -- feel free to edit this page.
Hibernate + Derby + Eclipse make a great GUI.
Spring + Hibernate + Derby -- DeveloperWorks article on integrating Spring and Hibernate that uses Derby as it's data source. Includes source code for the sample application.
DatabaseManager -- Recipe for a very simple class to manage Hibernate running on top of Derby.
As of Hibernate 3.1.2, Hibernate uses TableHiLoGenerator as the "native" generator instead of IdentityGenerator. I've documented this in this JIRA on Hiberate: HHH-1915 and for derby: DERBY-1518 (fixed).
Working with Derby and Hibernate shows how to get started.
Hibernate's Derby dialect: org.hibernate.dialect.DerbyDialect
What Does NOT Work
When you add a problem to the list below, please be sure to include the Hibernate version.
Hibernate Annotations do not work because Derby does not allow a unique column to be nullable. Version: hibernate-3.1beta1 and hibernate-annotations-3.1beta4
- The 'Create Schema' tool generates "bit" types, which derby does not recognize (Hibernate 3.0.5)
- The 'Create Schema' tool generates "if exists" when deleting tables, which derby does not recognize (Hibernate 3.0.5)
