The spec specifies flat transactions, but some app servers support nested transactions(Orion is one of them).

Hi All, I have a few Questions 1.How to decide between cmp and bmp. 2.There is no method newInstance() according to spec(if i am right) , then why is it specified as the first method called in and Entity Bean Life Cycle 3.Does EJB support Transactions based on the underlying Database.Like Does EJB support Nested Transaction only if Oracle supports.. Like that.
