I noticed I can specify default_schema and default_category in hibernate property configuration. When I use Hibernate Tool 3.2b8 with MySQL 5 I noticed there is no schema attribute generated when I set default_schema="name". Only category attribute is generated in hbm file when I provide default_category="name".

I am wondering what the difference is between schema and category, and how can I generate a schema attribute? Thanks!

hibernate only generates schema/catalog info iif they are different from default_schema/default_catalog

so if you want them in the files don't specify a default one...and if you don't want them for a specific catalog/schema then specify the default ones.
