    <p>First of all - do you <em>really</em> need JTA? Typically spring+hibernate don't require it. You can use a simple <code>JpaTransactionManager</code> / <code>HibernateTransactionManager</code>.</p> <p>If you really want JTA, then you will need a JTA provider. If not running in an application server, check <a href="https://stackoverflow.com/questions/2552612/how-to-use-jta-support-in-tomcat-6-for-hibernate">this question</a> for how to use JTA in a servlet container. (Also take a look at <a href="https://stackoverflow.com/questions/117751/spring-jta-transactionmanager-config-supporting-both-tomcat-and-jboss">this question</a>)</p> <p>Finally, <a href="http://community.jboss.org/wiki/sessionsandtransactions#Transactions" rel="nofollow noreferrer">hibernate docs</a> specify that, for container-managed transactions:</p> <blockquote> <p>Declarative transaction demarcation is a standard feature of EJB, also known as container-managed transactions (CMT). In EJB 2.x you would use XML deployment descriptors to create your transaction assembly. In EJB 3.x you can use JDK 5.0 annotation metadata directly in your source code, a much less verbose approach. To enable CMT transaction demarcation for EJBs in Hibernate configuration:</p> <ul> <li>set <code>hibernate.transaction.manager_lookup_class</code> to a lookup strategy for your JEE container</li> <li>set <code>hibernate.transaction.factory_class</code> to <code>org.hibernate.transaction.CMTTransactionFactory</code></li> </ul> </blockquote> <p>The second point is perhaps something you've missed?</p> <p>What the documentation says in addition to that (the next section) is that if you want declarative transaction, hibernate is not where you should look at. You'd need to create an interceptor. That's exactly what spring transaction managers are. And that would be my choice given your technology stack (Spring).</p> <p>If you wish not to rely on a single JTA provider, then make two builds. For example maven has "maven profiles", which allow to make builds for different environments.</p>

    1. COYes, JTA is required. I wonder why people always assume it's possible to answer a question by omitting one of the elements. For 'lookup_class' and 'factory_class', I didn't miss that part, but I *must* not be dependend on the JEE container that is used, the application is to be deployed on (at least) two different application servers.

    2. CO@mleduque people with broader view on technology assume some things because of their experience. For example I've rarely seen a spring app with JTA, while I've seen many cases when people throw themselves into it without actually needing it. For the rest of your comment - see my update.

    3. COwhy would anyone use the Spring TM layer... it does not do anything its just another layer with different method names and adds no new or better functionality over JTA. In the end its going to do a jndi lookup (if one uses the JTA impl) which ends up in the same problem of magic Strings and singletons.

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.
