Body
Closing the entire session factory <code>mHibernateSessionFactory.close()</code> in your DAO code is an obvious no-go. Also you can't access mSession after the factory has been closed, it is stated in the java docs. <code>void org.hibernate.SessionFactory.close() throws HibernateException</code> <blockquote> Destroy this SessionFactory and release all resources (caches, connection pools, etc). It is the responsibility of the application to ensure that there are no open sessions before calling this method as the impact on those sessions is indeterminate. </blockquote> If you are using the <code>getCurrentSession()</code> method, the typical pattern is to delegate the session opening and closing to Spring and use the <a href="http://static.springsource.org/spring/docs/3.0.x/reference/transaction.html#transaction-declarative" rel="nofollow">@Transactional</a> annotation <pre><code> @Override @Transactional public void empLogin_Dao(Employee employee) { System.out.println("m in dao"); //Please note that declaring mSession as a class member is another no-no //because DAO are typically singletons, so there's only ONE dao and ONE mSession variable //that will be shared by all users - it's possible your class mSession field will be accessed //simultaneously, which will lead to an exception Session mSession = mHibernateSessionFactory.getCurrentSession(); System.out.println(employee.getEmpID()); Query query = mSession .createQuery("from Employee where userName = :username "); query.setParameter("username", employee.getUserName()); List list = query.list(); } </code></pre> You can read about the rollback policy <a href="http://static.springsource.org/spring/docs/3.0.x/reference/transaction.html#transaction-declarative-rolling-back" rel="nofollow">here</a>.

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.
