i produce some java code and hbm files auto(use the hibernate.cfg.xml as connection),but after i produce the java code and hbm files,i had to add *.hbm file's path to hibernate.cfg.xml one by one,this action should be done by the hibernate tools aoto!

and you did not consider clicking the "generate hbm.cfg.xml" button ?

first time,i create the hibernate.cfg.xml,i map a new entity to hibernate.cfg.xml(add <mapping>...</mapping> node),the hibernate.cfg.xml should be update,not create the hibernate.cfg.xml again!!!!(here is just my logic).of course create the hibernate.cfg.xml can solve the question!
