    <p>I have an Java app, which i used to test with this persistence unit with in memory Derby driver:</p> <pre><code>&lt;persistence-unit name="TestPU" transaction-type="RESOURCE_LOCAL"&gt; &lt;provider&gt;org.hibernate.ejb.HibernatePersistence&lt;/provider&gt; &lt;properties&gt; &lt;property name="hibernate.connection.url" value="jdbc:derby:memory:ProjectDB"/&gt; &lt;property name="hibernate.connection.driver_class" value="org.apache.derby.jdbc.EmbeddedDriver"/&gt; &lt;property name="hibernate.dialect" value="org.hibernate.dialect.DerbyDialect"/&gt; &lt;property name="hibernate.hbm2ddl.auto" value="create-drop"/&gt; &lt;property name="hibernate.connection.username" value=""/&gt; &lt;property name="hibernate.connection.password" value=""/&gt; &lt;/properties&gt; </code></pre> <p></p> <p>Now i added an EJB service layer and i have been unable to write a working persistence unit using the same in memory db since. The following works fine, but i'd like to have it in memory</p> <pre><code>&lt;persistence-unit name="moduleNamePU" transaction-type="JTA"&gt; &lt;provider&gt;org.hibernate.ejb.HibernatePersistence&lt;/provider&gt; &lt;jta-data-source&gt;jdbc/sample&lt;/jta-data-source&gt; &lt;properties&gt; &lt;property name="hibernate.hbm2ddl.auto" value="create-drop"/&gt; &lt;/properties&gt; </code></pre> <p></p> <p>How can i alter the second persistence unit in order to work with in memory db?</p> <p>EDIT: As an EJB container i use Glassfish 3.1</p> <p>Entity Service:</p> <pre><code>@Stateless @Local(value=EntityServiceLocal.class) public class EntityService implements EntityServiceLocal { @EJB private EntityDaoLocal entityDao; @Resource private SessionContext ctx; public void setEntityDao(EntityDaoLocal entityDao) { this.entityDao = entityDao; } } </code></pre> <p>Dao Layer service:</p> <pre><code>@Stateless public class EntityDao implements EntityDaoLocal { @PersistenceContext private EntityManager em; } </code></pre>

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).
