<p></p> <p><b>New page</b></p><div>&#039;&#039;&#039;A typical message-driven object has the following characteristics:&#039;&#039;&#039;<br /> *Executes upon receipt of a single client message.<br /> *Is asynchronously invoked.<br /> *Can be transaction-aware.<br /> *May update shared data in an underlying database.<br /> *Does not represent directly shared data in the database, although it may access and update such data.<br /> *Is relatively short-lived.<br /> *Is stateless.<br /> *Is removed when the EJB container crashes. The container has to re-establish a new message-driven object to continue computation.<br /> <br /> ----<br /> <br /> A typical EJB container provides a scalable runtime environment to execute a large number of message-<br /> driven objects concurrently.</div>
