8.4 Client Tier Transactions

The J2EE platform does not require transaction support in applets and application clients, though like distributed transactions, a J2EE product might choose to provide this capability for added value. So, whether applets and application clients can directly access a UserTransaction object depends on the capabilities provided by the container. To ensure portability, applets and application clients should delegate transactional work to enterprise beans, either directly or by way of the Web tier.
