Java, Code Generation, and Persistence Frameworks

Question

Are there any Java code generation persistence frameworks? Something that is "database first" rather than object model first? I know this is probably heresy in the Java world, I'd just like to know if any frameworks like this exist.

I'm more of a .NET guy these days. So on the .NET-side tools like .NET Tiers or CSLA come to mind.

Answer 1

sure, hibernate and netbeans for example can reverse engineering a database. You may be want to look at:

• Hibernate Tools; site in maintenance
• netbeans, with recent version of netbeans you can create JPA entities from a JDBC connection

My 2 cents.

Answer 2

The Apache Cayenne ORM framework is able to reverse engineer a database. See here.
