    <p>On a glassfish 3.1 server, I have a <code>@Stateful</code> session bean which is injected into another stateful session bean.</p> <p>The stateful session bean which is injected presents my entity access layer, it itself has it's EntityManager injected with <code>@PersistenceContext</code> and it looks like this.</p> <pre><code>@Stateful MyEAO { @PersistenceContext EntityManager em; MyEAO() { // default constructor } .... } </code></pre> <p>This access layer is injected into another stateful bean:</p> <pre><code>@Stateful public class ShopAdmin implements ShopAdminInterface { @EJB MyEAO; .... } </code></pre> <p>This worked! - BUT NOW as soon as I added another constructor to MyEAO, injecting MyEAO into the 2nd bean fails with an exception.</p> <p>The strange thing is, that both beans used to be <code>@Stateless</code> session beans in the past and there were no problems at all.</p> <p>BTW, I used the second constructor to pass the entity manager for my JUnit tests which run outside of the glassfish container.</p> <p>Short: In the "stateless era" everything worked as expected!</p> <p>I'm quite new to EJB - so what am I missing here ?</p> <p>Here is the stack trace:</p> <pre><code>com.sun.faces.mgbean.ManagedBeanCreationException: Bei der Ressourcen-Einspeisung auf dem verwalteten Bean securityGuardBean ist ein Fehler aufgetreten. at

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).
