Hi,

I'm new to the forums and kinda new to the Hibernate. After reading a bit about it in Hibernate in Action book and about the HBM2DDL tool, I decided to come here in hope for a tip.

What I need to do is build a java class that uses SchemaExport to build the DDL schemas instead of using an ant to do the job.

Actually, I think I need a class that works like SchemaExport, but does the job without needing an ant.

So, basically I need to know if there's anything like that done already so that I can check out or if there's any tips (including places to go check by myself) you guys could share with me.

Ant is just java so AFAIK you should be able to use the classes that implement the ant task directly in your code.

If you have the hibernate source download then look at the source for SchemaExport and SchemaExportTask in the package org.hibernate.tool.hbm2ddl.

Good luck.

SchemaExport can be used from code. I use the following in my application to build the database. Is this what you're looking for?

Code:

new SchemaExport(configuration).create(false, true);

Sorry for not coming back earlier, but I solved the problem by myself. Thanks for the answers.

I kinda figured it out once my boss explained me exactly what I had to do.

I thought I had to reinvent the wheel or something... :P

The fact is I really just needed to use the SchemaExport Class. Like you said. Hibernate in Action was enough to give me this answers so I didn't come back earlier.

Thanks for the answers again. :)
