    <p>I have a form which when submitted stores data from it's fields to the database. The action forward in the struts-config maps back to the same page on Success/Failure of data insertion into the database. I would like to alert the user once this is successfully completed, so I set a session attribute(i.e. success/failure) in the method of the action class for the form. I then get and print out this session attribute once the jsp page has been accessed again.</p> <p>So far I have done this in the Action Class:</p> <pre><code> public static void setJavaScriptNotification(HttpServletRequest request, String notificationText) { HttpSession session = request.getSession(true); session.setAttribute("notification_javascript", notificationText); } </code></pre> <p>And in the jsp file that contains the form I have:</p> <pre><code> &lt;% String notificationJavaScript = (String) request.getSession().getAttribute("notification_javascript"); pageContext.setAttribute("notification_javascript", notificationJavaScript); request.getSession().removeAttribute("notification_javascript"); %&gt; &lt;html&gt; &lt;head&gt; &lt;logic:present name="notification_javascript"&gt; &lt;script type="text/javascript" language="JavaScript"&gt; function showAlerts() { alert("&lt;bean:write name="notification_javascript"/&gt;"); } &lt;/script&gt; &lt;/logic:present&gt; &lt;/head&gt; &lt;body onload="doPreOnload(); showAlerts();"&gt; </code></pre> <p>When I print out the session attributes in the jsp, I can't find the notification_javascript attribute. I'm new to HTTP, so I could be doing something wrong there.</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.
