    <p>I am very new to the whole J2EE architecture. Could somebody help me out?</p> <p>I have a Swing client with Login, Password fields on machine A.</p> <pre><code>Properties p = new Properties(); p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces"); p.put(Context.PROVIDER_URL, "jnp://localhost:1099/"); InitialContext ctx = new InitialContext(p); ejb = (MyBeanRemote) ctx.lookup("DemoServer/MyBean/remote"); </code></pre> <p>I have an EJB 3.0 on JBoss5 on machine B:</p> <pre><code>@Stateful @DeclareRoles({"editor", "viewer"}) public class MyBean implements MyBeanRemote, Serializable { @RolesAllowed({"editor"}) public boolean modify() throws Exception { if(!ctx.isCallerInRole("editor")) throw new SecurityException("Can't modify"); return true; } @RolesAllowed({"viewer","editor"}) public boolean view() throws Exception { if(!ctx.isCallerInRole("viewer")) throw new SecurityException("Can't view"); return true; } } </code></pre> <p>I have a DB with users and roles on server (conf/login-conf.xml):</p> <pre><code>&lt;application-policy name="jboss-secure"&gt; &lt;authentication&gt; &lt;login-module code="org.jboss.security.auth.spi.DatabaseServerLoginModule" flag="required"&gt; &lt;module-option name="unauthenticatedIdentity"&gt;guest&lt;/module-option&gt; &lt;module-option name="dsJndiName"&gt;java:/MyDerby&lt;/module-option&gt; &lt;module-option name="principalsQuery"&gt;SELECT Password FROM Users WHERE Username=?&lt;/module-option&gt; &lt;module-option name="rolesQuery"&gt;SELECT Role, 'Roles' FROM Users WHERE Username=?&lt;/module-option&gt; &lt;/login-module&gt; &lt;/authentication&gt; &lt;/application-policy&gt; </code></pre> <p>META-INF/jboss.xml:</p> <pre><code>&lt;jboss&gt; &lt;security-domain&gt;java:/jaas/jboss-secure&lt;/security-domain&gt; &lt;/jboss&gt; </code></pre> <p>As I understand, I shouldn't get ejb reference until client is authenticated properly. How do I use LoginContext, and do I use it at all? Can/should I use <code>@EJB private MyBeanRemote ejb</code>? And how do I make the whole thing work?</p> <p>I am just trying to build a seemingly trivial thing: authorization of application client. I feel stupid.</p> <p>Thank you very much.</p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
