Hibernate version: Hibernate 2.1

Hi, I'm new in hibernate.
I've create my first application with hibernate and it goes.
But now I've a question ... with hibernate mapping file and pojo must be in the same package?
I'd like have 2 package:
data.xml with all file .hbm.xml and
data.db with all pojo

If I try I've an error: the sistem doesn't find file.hbm.xml in package data.db. ...And in fact they aren't there...
Where can I tell in what package search my mapping file?
In hibernate.cfg.xml?

Thanks

How are you configuring your SessionFactory ?
If you're using the cfg.addClass(MyClass.class) then it will expect the mapping file to be in the same package. But if you use cfg.addResource("MyClass.hbm.xml") you specify the package of the pojo inside this file so you should be okay. Or,as you eluded to, if you specify the hbm files in the hibernate.cfg.xml, you should also be okay as long as the resource mappings point to the hbm files.

<mapping resource="data/xml/MyClass.hbm.xml"/>

All that said, I think most users prefer to keep these in the same package. It makes changing things easier since they're both in the same folder in the filesystem.

And if you're truely new to hibernate, I'd recommend using the 3.0x release.

Yep you can declare them in hibernate.cfg for example:

<session-factory>
<mapping
resource="com/yourco/blah/blah/MyMapping.hbm.xml"/>
</session-factory>

It is possible.You have to set absolute path for hbm.xml in .cfg.xml
