Hi,
Is there a way to dynamically load hbm files (meaning after the java process startup and before I start using the database)? If so can I just load it using my class loader?
Where should I place the hbm files when I use Dynamic models?


Thanks,
Adi.

This is not built into Hibernate.

But I'm on such a project and I can dynamically load mappings... But I do NOT use POJOs. This therefore means that if you do and your classes do not exist, you will fail to spawn a new session factory - which is no biggy since it won't scrap the existing one.

If you're interested, let me know.

Sure I'm interested, I use dynamic models so if I could load hbm files after startup it will be great.
Where do you load the mapping to? Is it to memory or you just add it as a resource in your class loader?

Regards,
Adi.

Well, I take a different approach: it's the user who submits a new mapping (I call this "object model") to the core via a Web interface. I then validate this model using Hibernate's Configuration object, and if the validation is OK, I replace the current SessionFactory.

I don't use the Configuration's .addResource(), or .addFile() method (although it could be possible). I use .addXML(), which takes an XML string corresponding to the mapping (and which I serialize to the database).
