I have tried this :

path = "./hib.cfg.xml"

annCfg.configure(path);

changeContent(path);

annCfg.configure(path);

Changings don't take effects. I don't understand why the configuration doesn't change. I would like to delete the first for reloading the second. How could i change mappings (delete add) of a configuration.

As far as I know, Hibernate does not support 'hot deployment' of mapping files. And therefore you have to restart your server.

Well, I don't know what your "server" is. If you would use JBoss and redeploy the application, the Hibernate mapping will automatically be reconfigured.

I've found a solution but I don't know if it's good (it works but is there desallocation problems ???). The mapping is reloaded only if I change the name of the .cgf file. I use current time to name the file.
