Hello :)

What would be the best way to map the following many-to-many situation?

I want to map User (userId, username, password, firstname, lastname, roles)

to

Role (roleId, name)

A role is really just a name and the system contains 4 roles (admin, user, etc). Each User can have one or more roles, and each Role can be assigned to one or more Users. These roles never change, so what I need in the database is a USER table with user data and a ROLE table with just 4 records that never change and an association table between them.

Is there a way to specify the roles in a HBM mapping, kinda like an Enum?
