If you’re unsure about how to set up transactions in an enterprise bean, here’s a tip: In the bean’s deployment descriptor, specify container-managed transactions. Then, set the Required transaction attribute for the entire bean. This approach will work most of the time.
Table 14-2 lists the types of transactions that are allowed for the different types of enterprise beans. An entity bean must use container-managed transactions. With container-managed transactions, you specify the transaction attributes in the deployment descriptor and you roll back a transaction with the setRollbackOnly method of the EJBContext interface.
