J2EE.9.3 Transactions

Application clients are not required to have direct access to the transaction facilities of the J2EE platform. A J2EE product is not required to provide a JTA User Transaction object for use by application clients. Of course, application clients can invoke enterprise beans that start transaction, and they can use the transaction facilities of the JDBC API. If a JDBC API transaction is open when an application client invokes an enterprise bean, the transaction context is not required to be propagated to the EJB server.
