Hi Alejandro....
I also have been wondering it there is a mechanism to do classpath scanning
to load the resources...
I have a couple of thoughts on this
1. When we move to OSGi in the relatively near future then we could use
OSGi extender patter to have each module declare the model objects that
provide and have a hibernate module automatically detect them and create the
hibernate session. It is described here:
http://www.osgi.org/blog/2007/06/osgi-and-hibernate.html
2. Since we are not currently using OSGi however we can use spring to do
something similar. We can create a HibernateClassesFactoryBean that gathers
up the classes and creates a list that can be used as input to
AnnotationSessionFactoryBean I'm not exactly sure how to do this but in
Spring 2.5 there is a some package scanning that happens that might help.
That's where I'd look if I were trying to get that working myself.
Maybe I'll add that as a to do item for my 'sample app' that I'm using to
help with the DevJam architecture stuff
Hope that helps!
