dear slack –
Currently, the only way to add properties after generating the config file is to do it manually (beware that adding mappings regens the config file and whacks your changes), or just whack the original config file and create a new one (use New -> Other -> J2EE -> Hibernate 2.1 -> Hibernate Config File) – just remember to add your mapping files into the config file at that time.
Not sure if the hib.properties thing would work or not – is this a Hibernate feature?
