    <p>It's not working in your example because the <code>ATTR_CURRENT_USER</code> constant is not visible to the JSTL tags, which expect properties to be exposed by getter functions. I haven't tried it, but the cleanest way to expose your constants appears to be the <a href="http://jakarta.apache.org/taglibs/sandbox/doc/unstandard-doc/index.html#useConstants" rel="nofollow noreferrer" title="Unstandard tag library from Apache">unstandard tag library</a>.</p> <p>ETA: Old link I gave didn't work. New links can be found in this answer: <a href="https://stackoverflow.com/questions/127328/java-constants-in-jsp">Java constants in JSP</a></p> <p>Code snippets to clarify the behavior you're seeing: Sample class:</p> <pre><code>package com.example; public class Constants { // attribute, visible to the scriptlet public static final String ATTR_CURRENT_USER = "current.user"; // getter function; // name modified to make it clear, later on, // that I am calling this function // and not accessing the constant public String getATTR_CURRENT_USER_FUNC() { return ATTR_CURRENT_USER; } } </code></pre> <p>Snippet of the JSP page, showing sample usage: </p> <pre><code>&lt;%-- Set up the current user --%&gt; &lt;% session.setAttribute("current.user", "Me"); %&gt; &lt;%-- scriptlets --%&gt; &lt;%@ page import="com.example.Constants" %&gt; &lt;h1&gt;Using scriptlets&lt;/h1&gt; &lt;h3&gt;Constants.ATTR_CURRENT_USER&lt;/h3&gt; &lt;%=Constants.ATTR_CURRENT_USER%&gt; &lt;br /&gt; &lt;h3&gt;Session[Constants.ATTR_CURRENT_USER]&lt;/h3&gt; &lt;%=session.getAttribute(Constants.ATTR_CURRENT_USER)%&gt; &lt;%-- JSTL --%&gt; &lt;%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %&gt; &lt;jsp:useBean id="cons" class="com.example.Constants" scope="session"/&gt; &lt;h1&gt;Using JSTL&lt;/h1&gt; &lt;h3&gt;Constants.getATTR_CURRENT_USER_FUNC()&lt;/h3&gt; &lt;c:out value="${cons.ATTR_CURRENT_USER_FUNC}"/&gt; &lt;h3&gt;Session[Constants.getATTR_CURRENT_USER_FUNC()]&lt;/h3&gt; &lt;c:out value="${sessionScope[cons.ATTR_CURRENT_USER_FUNC]}"/&gt; &lt;h3&gt;Constants.ATTR_CURRENT_USER&lt;/h3&gt; &lt;c:out value="${sessionScope[Constants.ATTR_CURRENT_USER]}"/&gt; &lt;%-- Commented out, because otherwise will error: The class 'com.example.Constants' does not have the property 'ATTR_CURRENT_USER'. &lt;h3&gt;cons.ATTR_CURRENT_USER&lt;/h3&gt; &lt;c:out value="${sessionScope[cons.ATTR_CURRENT_USER]}"/&gt; --%&gt; &lt;hr /&gt; </code></pre> <p>This outputs: </p> <h1>Using scriptlets</h1> <h3>Constants.ATTR_CURRENT_USER</h3> <p>current.user <br /></p> <h3>Session[Constants.ATTR_CURRENT_USER]</h3> <p>Me</p> <hr /> <h1>Using JSTL</h1> <h3>Constants.getATTR_CURRENT_USER_FUNC()</h3> <p>current.user</p> <h3>Session[Constants.getATTR_CURRENT_USER_FUNC()]</h3> <p>Me</p> <h3>Constants.ATTR_CURRENT_USER</h3> <p><br /><hr /></p>

    1. COAwesome answer! I can't seem to find a way to download the unstandard taglib, do you know if it's still available?

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).
