I'm running Sun One Appserver 8. I have a hibernate.properties that configures the database specifics and I use Configuration.addClass() to specify the classes to be mapped.

I just can't seem to find where to put the hibernate.properties so that it will be found. The reason that I'm not using an XML config is because I am specifying my mapping with addClass(), and the XML parser complains if my hibernate.cfg.xml doesn't have at least one mapping tag.

Can anyone give me a hand?

You should put it somewhere in the root of the classpath for your application.
