Re: [Hibernate] extends Configuration Tricks

[Max R. A. <max...@jb...>]

oh and of course Hibernate Tools relies on being able to access a fully  
build Configuration
without any need of reflection (assuming the types have been specified in  
the mappings by the user)

A request for enhancement would be somehow for me to hook into these  
reflection calls so i could
provide my own "worldview" to it e.g. from Eclipse's sourcemodel (it is  
definitly not a requirement;
but could give me some nice ways of building a SessionFactory without the  
actual classes having to be loaded)
