Comments:

It's today's checked out hbm2java ant task (hibernate 3) from sourcesafe. I had never tried before 2 classes with same name but distinct tables and packages on hibernate, and I don't know if it's a know limitation or a bug, or maybe something that I'm not doing right ;)
But I thought it may be a situtation that may happen in a large system.

Thanks

that is an illegal hibernate mapping! you need to use entity-name to have the same class mapped twice. (btw. i actually dont know how hbm2java will react on this since it would need to merge these two classes to get the proper mapping)

But it´s not the same class, that's two different classes that happens to have the same name (but not package), each in a different hbm file and table and methods and so on. What identifies a java class is not only it´s name but name+package right ? (at least in java language)
I haven´t tried entity-name yet, but seems to be for another propouse (using maps instead of classes or mapping a class to two tables ?)
is package1.Class1 == package2.Class1 ?
Thanks

if you have non-unique class names (without the package name) you will have to disable auto-import for one of them.
