    <p>I am trying to create transaction manager and use it with Hibernate for Oracle.</p> <p>My persistence.xml file is:</p> <pre><code>&lt;persistence-unit name="org.drools.persistence.jpa" transaction-type="JTA"&gt; &lt;provider&gt;org.hibernate.ejb.HibernatePersistence&lt;/provider&gt; &lt;jta-data-source&gt;jdbc/testDS1&lt;/jta-data-source&gt; &lt;class&gt;org.drools.persistence.session.SessionInfo&lt;/class&gt; &lt;class&gt;org.jbpm.persistence.processinstance.ProcessInstanceInfo&lt;/class&gt; &lt;class&gt;org.drools.persistence.processinstance.WorkItemInfo&lt;/class&gt; &lt;exclude-unlisted-classes&gt;true&lt;/exclude-unlisted-classes&gt; &lt;properties&gt; &lt;property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" /&gt; &lt;property name="hibernate.connection.autocommit" value="false" /&gt; &lt;property name="hibernate.max_fetch_depth" value="3" /&gt; &lt;property name="hibernate.jndi.class" value="bitronix.tm.jndi.BitronixInitialContextFactory"/&gt; &lt;property name="hibernate.show_sql" value="true" /&gt; &lt;property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.BTMTransactionManagerLookup" /&gt; &lt;/properties&gt; &lt;/persistence-unit&gt; </code></pre> <p>In applicationContext.xml of spring I added:</p> <pre><code>&lt;bean id="dataSource" class="bitronix.tm.resource.jdbc.PoolingDataSource" init-method="init" destroy-method="close"&gt; &lt;property name="className" value="oracle.jdbc.xa.client.OracleXADataSource" /&gt; &lt;property name="uniqueName" value="jdbc/testDS1" /&gt; &lt;property name="minPoolSize" value="1" /&gt; &lt;property name="maxPoolSize" value="5" /&gt; &lt;property name="driverProperties"&gt; &lt;props&gt; &lt;prop key="URL"&gt;myURL&lt;/prop&gt; &lt;prop key="user"&gt;username&lt;/prop&gt; &lt;prop key="password"&gt;password&lt;/prop&gt; &lt;/props&gt; &lt;/property&gt; &lt;/bean&gt; &lt;bean id="txManager" class="org.springframework.transaction.jta.JtaTransactionManager"&gt; &lt;property name="transactionManager" ref="bitronixTransactionManager"/&gt; &lt;property name="userTransaction" ref="bitronixTransactionManager"/&gt; &lt;/bean&gt; &lt;bean id="bitronixTransactionManager" factory-method="getTransactionManager" class="bitronix.tm.TransactionManagerServices" depends-on="dataSource,txManager" destroy-method="shutdown"/&gt; </code></pre> <p>However, when I run:</p> <pre><code>EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.drools.persistence.jpa"); </code></pre> <p>I get an exception:</p> <pre><code>Caused by: org.hibernate.HibernateException: Could not find datasource: jdbc/testDS1 </code></pre> <p>The exception is on <code>ds = (DataSource ) NamingHelper.getInitialContext(props).lookup(jndiName);</code> of Hibernate infra file.</p> <ol> <li><p>What could be the problem?</p></li> <li><p>How does Hibernate persistence knows to refer to spring <code>txManager</code> bean?</p></li> </ol>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
