How to generate DDL in Hiberante3 with annotations aproach

rocket · **Posted:** Fri Feb 04, 2005 12:19 pm

Hibernate version:
3beta3

Name and version of the database you are using:
Postgres 8rc1 on WindowsXP

In Hibernate2x I use xdoclet to create hbm files and Ant task to generate DDL scripts...

But, in Hibernate3, using Java annotations (in ejb3 on JBoss) how can I create DDL script?

I know that's possible to use

Code:

hibernate.hbm2ddl.auto=create

property in ejb3 package, but I can't use It.

I just wrote a little program that uses the SchemaExport class programatically like the following.

Code:

SchemaExport se = new SchemaExport(SessionHelper.getConfiguration());
se.create(true, true);

It would be great it someone could write a new ant task based on the old one to handle schema generation.
Most certainly not so long.

How do you see this working with regard to the separation between Hibernate and Hibernate-Annotations?

I guess the options are either adapt SchemaExportTask.getConfiguration() in Hibernate to attempt to construct an AnnotationConfiguration via reflection, or provide an annotation-specific version of SchemaExportTask that explicity creates an AnnotationConfiguration.

STOP! ;)

we have an ant task for this (committed last week) in the tools package.

it will be part of the soon to be here tools release.

you can go build it from cvs if you want.

Super, I assume you meant:

I'll look forward to the alpha3 release!
