Body
Hm, i got it to work. <ol> <li>To test Transactions: a simple <code>em.flush()</code> is all i need (thanks to @TaoufikMohdit for the idea). If there is no transaction, <code>flush()</code> throws a <code>TransactionRequiredException</code>!</li> <li><code>@Transactional</code> is for Spring-Managed-Beans only. So i create a Service: <pre><code>@Service public class BasicTransactionalService { @PersistenceContext HibernateEntityManager em; @Transactional public void testFlushInTransactional() { em.flush(); } @Deprecated public void testFlushOutsideTransactional() { em.flush(); } @Transactional public void testFlushSubroutineTransactional() { testFlushOutsideTransactional(); } } </code></pre></li> <li>I changed the Tests to: <pre><code>@Autowired BasicTransactionalService bean; @Test public void testTransactionIsolation() { bean.testFlushInTransactional(); } @Test(expected = TransactionRequiredException.class) @SuppressWarnings("deprecation") public void testThrowsTransactionRequiredException() { bean.testFlushOutsideTransactional(); } @Test public void testTransactionalSubroutine(){ bean.testFlushSubroutineTransactional(); } </code></pre></li> </ol> Now it works fine. BTW This is my <code>app-config.xml</code> <pre><code><beans> <bean class="BasicTransactionalService" /> <bean class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean" /> <bean class="org.springframework.orm.jpa.JpaTransactionManager" /> <tx:annotation-driven /> <beans> </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
