    <p>I came up with the following solution to add roles programmatically after login, which works at least on GlassFish 3.1.2 build 23.</p> <pre><code>import com.sun.enterprise.security.SecurityContext; import com.sun.enterprise.security.web.integration.PrincipalGroupFactory; import java.security.Principal; import java.util.Set; import javax.security.auth.Subject; import org.glassfish.security.common.Group; public class GlassFishUtils { public static void addGroupToCurrentUser(String groupName, String realmName) { Subject subject = SecurityContext.getCurrent().getSubject(); Set&lt;Principal&gt; principals = subject.getPrincipals(); Group group = PrincipalGroupFactory.getGroupInstance(groupName, realmName); if (!principals.contains(group)) principals.add(group); } } </code></pre> <p>You will need to add <code>security.jar</code> and <code>common-util.jar</code> from GlassFish to your project libraries.</p> <p>And don't forget to create a <code>&lt;security-role&gt;</code> section in your web.xml for the roles you wish to add.</p> <p>Note that I am using functionality which does not appear to be part of a published stable API, so there is no guarantee that this will keep working in future releases of GlassFish.</p> <p>I got the information on how to add roles from the source code of <code>sun.appserv.security.AppservPasswordLoginModule.commit()</code> of GlassFish. If a future GlassFish release breaks my code, this function would be a good place to start in order to find out how to fix it.</p>

    1. CONice solution for one part of the problem. However, I still have to define the roles statically inside the web.xml. But I want to add roles dynamically without having to restart the Server. We ended up doing it a different way. Cannot remember in detail, but I think we replaced a big part of the Glassfish security mechanism with our own.

    2. COI agree with ifischer. The only real solution is not having to add anything statically. This should be added to the spec really. The forced declaration might seem to have been a good idea once, but in practice it's severely limiting and especially in Glassfish needlesly verbose.

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.
