    <p>Is it possible to override the "directory.path" variable without recompiling the class. Add a <code>web.xml</code> file to your <code>WEB-INF</code> folder, that defines a a new init parameter.</p> <p>Change the <code>servlet-class</code> to the actual servlet class you are using.</p> <p>A restart of the container is necessary in order to take the changes into consideration, but no recompiling / rebuilding is needed.</p> <pre class="lang-xml prettyprint-override"><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"&gt; &lt;servlet&gt; &lt;servlet-name&gt;MyServletLinkName&lt;/servlet-name&gt; &lt;servlet-class&gt;your.path.to.servlet.YourServlet&lt;/servlet-class&gt; &lt;init-param&gt; &lt;param-name&gt;directory.path&lt;/param-name&gt; &lt;param-value&gt;/new/path&lt;/param-value&gt; &lt;/init-param&gt; &lt;/servlet&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;MyServletLinkName&lt;/servlet-name&gt; &lt;url-pattern&gt;/GetInfo&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; &lt;/web-app&gt; </code></pre> <p><strong>EDIT:</strong></p> <p>If you want to use a dynamic parameter that changes while the application runs, you could use a properties file that it is watched by a thread and inspected in a interval of X seconds.</p> <p>You may use a context param containing the location of the file together with a context initialized listener. The listener creates a watcher thread that updates some public variable that it is accessible by all your servlets.</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).
