<p>In EJB 3.0 applications, transaction properties are most frequently declared for methods in session beans. If a method requires transaction, all operations in the method, including database updates, are only committed after the method exits normally. If an uncaught application exception is thrown in this method (or in the methods it calls), the transaction manager rolls back all the changes (i.e., database updates). The transaction declaration annotation is <code>@TransactionAttribute</code>. It can take the following arguments.</p>
-
-<ul>
- <li><code>REQUIRED</code>: The annotated method is executed within a transaction. If the caller method is already inside a transaction, the transaction is used; if not, a new transaction is generated.</li>
-
- <li><code>MANDATORY</code>: The annotated method must be invoked inside a transaction (i.e., the caller must have a transaction already). Otherwise, an error is thrown.</li>
-
- <li><code>REQUIRESNEW</code>: The annotated method is executed within a newly generated transaction. If the caller method is already in a transaction, it is suspended.</li>
-
- <li><code>SUPPORTS</code>: If the annotated method is called within a transaction, the transaction is used. If it is called without a transaction, no transaction will be created.</li>
-
- <li><code>NOT_SUPPORTED</code>: If the annotated method is called within a transaction, an error will be thrown.</li>
-</ul>
-
-<p>If a method does not have a transaction annotation, it is assigned the default transaction property <code>REQUIRED</code> by the EJB 3.0 container.</p>
-
-<p>In EJB 3.0, the <code>EntityManager</code> must run in a transactional context to ensure the database integrity. The transaction manager always synchronizes the database when it commits (recall that, by default, the database is synchronized at the end of the current thread), or before the next database query, whichever comes first. You can call <code>EntityManager.flush()</code> to flush the in-memory updates to the database in the middle of a transaction.</p>

+<p>Click on the following button to launch the new currency update application. Try to update the currency several times and you will see either all the records are updated or none of the records is updated. There is no case when only part of the records are updated, even the exceptions are thrown in the middle of the updating loop. The exception is thrown for about half of the updates.</p>
