    <p>If it are application wide constants, just put them in the application scope during application startup. You can use the <code>init()</code> method of an arbitrary servlet for this or, better, a <code>ServletContextListener</code>.</p> <pre><code>@WebListener public class Config implements ServletContextListener { @Override public void contextInitialized(ServletContextEvent event) { Map&lt;String, String&gt; creditCardTypes = new LinkedHashMap&lt;String, String&gt;(); creditCardTypes.put("M0", "MasterCard"); creditCardTypes.put("D0", "Discover"); // ... event.getServletContext().setAttribute("creditCardTypes", creditCardTypes); } // ... } </code></pre> <p><em>(note that I used <code>LinkedHashMap</code> as it maintains insertion order in contrary to <code>HashMap</code>)</em></p> <p>This way it's available as <code>${creditCardTypes}</code> by EL in any JSP. You can then use <a href="https://stackoverflow.com/tags/jstl/info">JSTL</a> <code>&lt;c:forEach&gt;</code> to iterate over it. It also supports iterating over a <code>Map</code> and each iteration will give a <a href="http://download.oracle.com/javase/6/docs/api/java/util/Map.Entry.html" rel="nofollow noreferrer"><code>Map.Entry</code></a> back which in turn has <code>getKey()</code> and <code>getValue()</code> methods which are accessible in EL as well.</p> <pre><code>&lt;%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %&gt; ... &lt;select id="creditCardType" title="select card type" name="creditCardType"&gt; &lt;c:forEach items="${creditCardTypes}" var="creditCardType"&gt; &lt;option value="${creditCardType.key}"&gt;${creditCardType.value}&lt;/option&gt; &lt;/c:forEach&gt; &lt;/select&gt; </code></pre>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
