The problem is probably due to having no persistent fields in the bean.
The second constructor's arguments would be the list of persistent
fields that fit the VO's 'match' parameter (match="*" in your case).

Just an option. If you don't include a class-level @ejb.dao tag, it
won't generate a DAO for the bean nor insert the calls to it.
