Re: Maven + HIbernate3 + Annotations, problems with SchemaExport

Hendrik,

I found this out the hard way not long after asking for help. It
always seems that I beat my head against the proverbial wall for what
seems like an eternity, ask for help, and then find the answer.

Adding the mapping in the hibernate configuration does indeed work. I
tried the "package" attribute, but it seems that when that mapping is
used Hibernate expects a class called 'package-info' to live in the
package with annotations that map to all of the annotated class files.
The package-info class doesn't appear to be documented anywhere based
upon my searching. It's mentioned in the hibernate annotation
documentation briefly, but with any real explanation.

Since this is likely to be a simple application running in a servlet
container and not a full blown J2EE stack I was hoping to find a way
to have Hibernate "discover" all the annotated classes without
explicit mappings. I'm fine with creating the mappings, I just missed
that step initially.

Thank you for the help!
