    <p>I'm migrating a web app to Spring 3.2 and am enjoying the web.xml-free configuration. One part that's remaining is setting the webapp root key, which I previously did in web.xml like so:</p> <pre><code>&lt;context-param&gt; &lt;param-name&gt;webAppRootKey&lt;/param-name&gt; &lt;param-value&gt;webapproot&lt;/param-value&gt; &lt;/context-param&gt; </code></pre> <p>I know that Spring creates a default key, but in my case I'm running multiple versions of the same war and need to set the key to a different value in each. So optimally I'd like to take a value from a properties file and use that as the rootkey.</p> <p>I imagine that I would do this somewhere here:</p> <pre><code>public class WebAppInitializer implements WebApplicationInitializer { private static final Logger logger = Logger.getLogger(WebAppInitializer.class); @Override public void onStartup(ServletContext servletContext) throws ServletException { // Create the root appcontext AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext(); rootContext.register(AppConfig.class); servletContext.addListener(new WebAppRootListener()); // Manage the lifecycle of the root appcontext servletContext.addListener(new ContextLoaderListener(rootContext)); //servletContext.setInitParameter("defaultHtmlEscape", "true"); // The main Spring MVC servlet. ServletRegistration.Dynamic springapp = servletContext.addServlet( "springapp", new DispatcherServlet(rootContext)); springapp.setLoadOnStartup(1); Set&lt;String&gt; mappingConflicts = springapp.addMapping("/"); ...etc... </code></pre> <p>Thanks to anyone who can offer advice!</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.
