JPA Hibernate @Version annotations and BOOL/TinyInt(1) => boolean mapping

Just starting out with JPA using Hibernate, and I'm able to autogenerate my persistence.xml file and related Object classes from my MySQL DB.  But there are a couple of "fix-ups" I seem to have to do after-the-fact that are a bit tedious and I was hoping to find a way to configure them as the defaults.

First, columns in my MySQL table that are BOOL (well, I guess technically TinyInt(1)) end up mapping to byte by default.  I can go through each one and change it to boolean from the Import Database Schema dialog window, but it's a bit of a pain to have to do this for each one.  Is there a way to change the default mapping?

Second, I'm using optimistic locking with a version field.  If I go in and add the @Version annotation to the generate classes, everything works great.  But I'd rather not have to do that after they're generated.  Is there a way to get the generated classes to add them automatically?

Thanks,

Doug
