    <p>I understand that you're checking the presence of the logged-in user before displaying the content. This <em>may</em> be okay this way, but any user who opens the page without being logged-in will receive blank content. This is not very user friendly. You'd like to redirect a non-logged-in user to the login page.</p> <p>This is normally already taken into account if you're using Java EE provided container managed authentication. But if you're homegrowing authentication, you'd need to create a <a href="https://stackoverflow.com/tags/servlet-filters/info">servlet filter</a> for this. If you collect all restricted pages in a common folder like <code>/app</code> so that you can use a common URL pattern for the filter, e.g. <code>/app/*</code> (and put all public pages such as the login page <em>outside</em> this folder), then you should be able to filter out non-logged-in users as follows, assuming that <code>#{userBean}</code> is a session scoped JSF <code>@ManagedBean</code> or some session attribute which you've put in session scope yourself:</p> <pre><code>@WebFilter("/app/*") public class LoginFilter implements Filter { @Override public void init(FilterConfig config) throws ServletException { // NOOP. } @Override public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { HttpServletRequest request = (HttpServletRequest) req; HttpServletResponse response = (HttpServletResponse) res; HttpSession session = request.getSession(false); UserBean user = (session != null) ? (UserBean) session.getAttribute("userBean") : null; if (user == null || user.getCognome() == null) { response.sendRedirect(request.getContextPath() + "/login.xhtml"); // No logged-in user found, so redirect to login page. } else { chain.doFilter(req, res); // Logged-in user found, so just continue request. } } @Override public void destroy() { // NOOP. } } </code></pre> <h3>See also:</h3> <ul> <li><a href="https://stackoverflow.com/questions/9965708/how-to-handle-authentication-authorization-with-users-in-a-database">How to handle authentication/authorization with users in a database?</a></li> </ul>

    3. COYou're welcome. To give the bounty, I believe you have to click some other button right below the accept button (which the answerer can't see, but the asker can "see"). But you can also wait for the bounty period to be ended, the bounty will then automatically be awarded to the accepted answer, if it has at least 2 upvotes.

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.
