    <blockquote> <p>(...) all actual business logic lies in "manager" classes to which the session beans forward their calls.</p> </blockquote> <p>That was a very common pattern with EJB 2.x allowing to unit test the "manager" classes easily, outside the container, without any adherence to the EJB API.</p> <blockquote> <p>Can I somehow make these manager classes capable of being injected into the EJBs via @Resource and then having the other EJBs injected into them via @EJB?</p> </blockquote> <p>Not out-of-the-box with Java EE 5. Injection is limited only to first class constructs defined in the Java EE platform, including:</p> <ul> <li><code>SessionContext</code> object</li> <li><code>DataSources</code> object</li> <li><code>UserTransaction</code></li> <li><code>EntityManager</code> interface</li> <li><code>TimerService</code> interface</li> <li>Other enterprise beans</li> <li>Web services</li> <li>Message queues and topics</li> <li>Connection factories for resource adaptes</li> <li>Environment entries limited to String, Character, Byte, Short, Integer, Long, Boolean, Double, and Float.</li> </ul> <p>In Java EE 6, this would be possible using CDI (<a href="http://jcp.org/en/jsr/detail?id=299" rel="nofollow noreferrer">JSR-199</a>) and the <code>@Inject</code> annotation in EJBs to inject your managers and also in you managers to get EJBs injected. </p> <p><strong>Maybe</strong> you could try to deploy <a href="http://seamframework.org/Weld" rel="nofollow noreferrer">Weld</a> (the RI of JSR-199) as part of your application on GlassFish v2.1. I didn't experiment this myself, so I can't confirm anything. Just in case, maybe have a look at the <a href="http://docs.jboss.org/weld/reference/1.0.0/en-US/html/environments.html" rel="nofollow noreferrer">Chapter 18. Application servers and environments supported by Weld</a> (GlassFish v2.1 hasn't been tested, but it doesn't mean it doesn't work).</p>

    1. COUgh, that's what I feared. Will look into Weld, but this being a corporate environment (which is the reason for Glassfish 2), it's probably not allowed.

    2. COAt least you HAVE glassfish so upgrading is at least _possible_ :) Weld can run in a servlet 2.5 environment by the way.

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).
