Would you tell me why:

public int ejbCreate() throws javax.ejb.CreateException

is not a valid create method in a CMP entity bean?

According to EJB specification Page 197, the return type of ejbCreate()
should be primary key class, which must provide suitable implementation of hashCode() and equals(Object) methods.

So that will rule out primitives, it can be wrapper classes though.
