primary key field confusion

I've posted this question in the EJB 3.0 Persistence forum but I think it is a general Hibernate problem.
Basically I have a class with two fields: id and uuid. Uuid is the primary key field. When I write a Hibernate query that references the id field, it gets translated into the uuid field.

See this thread for details:

There is no way around it: 'id' has specific meaning in the Hibernate's HQL, that is why it gets resolved into uuid.

You need to have a different name (or accessors) for that 'id' field for Hibernate to work with it.

Simplest way is to rename 'id' to something like 'businessId'

Thanks for your answer.
However, I'm using the EntityManager and EJBQL 3.0. Does 'id' also have a predefined meaning in EJB 3.0?

Renaming is not an option. What else can I do?
