    <blockquote> <p><em>I've read there is no need to mention the servlet in web.xml.</em></p> </blockquote> <p>You're probably confusing with the legacy Tomcat-builtin <a href="http://tomcat.apache.org/tomcat-4.1-doc/catalina/funcspecs/fs-invoker.html" rel="nofollow noreferrer"><code>InvokerServlet</code></a> which was present in older versions of Apache Tomcat (and still mentioned in poor and outdated tutorials/books). It indeed allowed to invoke servlets like that without the need to map anything. However, it was later confirmed that it was a <a href="http://wiki.apache.org/tomcat/FAQ/Miscellaneous#Q3" rel="nofollow noreferrer">security hole and vulrenable to attacks</a>. It was disabled and deprecated on Tomcat 5.0 and removed on Tomcat 7.0. In such case, you really need to map your servlet in <code>web.xml</code> (and put it in a package!).</p> <p>Another source of confusion may be the new Servlet 3.0 <a href="http://download.oracle.com/javaee/6/api/javax/servlet/annotation/WebServlet.html" rel="nofollow noreferrer"><code>@WebServlet</code></a> annotation. When you're already using a Servlet 3.0 container like Tomcat 7.0, then you could use this annotation to map the servlet without the need to fiddle with <code>web.xml</code>.</p> <pre><code>package com.example; @WebServlet("/MyServlet") public class MyServlet extends HttpServlet { // ... } </code></pre> <p>Then you'll be able to access it the way you want.</p> <h3>See also:</h3> <ul> <li><a href="https://stackoverflow.com/tags/servlets/info">Our Servlets wiki page</a></li> </ul>

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.
