    <p>I am experimenting with Hibernate 4.1.2. </p> <p>Wrote the following class to help me get a session using new ServiceRegistry approach</p> <p>=====================================================</p> <pre><code>package com.debaself.samples; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.cfg.AnnotationConfiguration; import org.hibernate.cfg.Configuration; import org.hibernate.service.ServiceRegistry; import org.hibernate.service.ServiceRegistryBuilder; public class SessionFetch { private static SessionFactory sessionFactory = null; public SessionFactory getSessionFactory(){ if(sessionFactory == null){ Configuration cfg = new AnnotationConfiguration().addResource("hibernate.cfg.xml").configure(); ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(cfg.getProperties()).buildServiceRegistry(); sessionFactory = cfg.buildSessionFactory(serviceRegistry); } return sessionFactory ; } public Session getSession(){ return getSessionFactory().openSession(); } } </code></pre> <p>=============================================== </p> <p>Now I wrote a test</p> <p>===============================================</p> <pre><code>public class SessionFetchTest { @Test public void getSessionFactoryTest(){ SessionFetch fetch = new SessionFetch(); SessionFactory factory = fetch.getSessionFactory(); assertNotNull(factory); assert(!factory.isClosed()); factory.close(); } @Test public void getSessionTest(){ SessionFetch fetch = new SessionFetch(); Session session = fetch.getSession(); assert(session.isOpen()); assert(session.isConnected()); } } </code></pre> <p>==================================================</p> <p>The weirdness is </p> <p>when I run the test methods individually both tests succeed. But when I run them in one go the getSessionTest() invariably fails and throws an UnknownServiceException. </p> <p>Can anyone explain this behaviour please?</p>

    1. COMy first guess is its something to do with the static member of type SessionFactory but still I do not have a definitive answer for this.

    2. COI guess because you close the session factory in your first test ...

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).
