    <p>As for every "3rd party library" which you'd like to use in your webapp, just put them in <code>/WEB-INF/lib</code> folder of your web project. This way it will automatically be taken in the classpath/buildpath.</p> <p>You only need to ensure that you have <strong>not</strong> extracted the JAR file(s) and placed its loose contents in the classpath as well and/or hardcoded the taglibs in webapp's own <code>web.xml</code>. Some poor online tutorials such as <em>roseindia</em> (cough) namely suggests it that way. Don't do that. It will make things only worse.</p> <p>Then, in your JSP files ensure that you're using the right taglib URI's as outlined in the <a href="http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/" rel="noreferrer">JSTL TLD documentation</a>. For example, <a href="http://java.sun.com/products/jsp/jstl/1.1/docs/tlddocs/c/tld-summary.html" rel="noreferrer">JSTL core</a> needs to be declared as follows:</p> <pre><code>&lt;%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %&gt; </code></pre> <p>Note the <code>/jsp</code> path. It was introduced since JSTL 1.1. The JSTL 1.0 doesn't have the <code>/jsp</code> path. If you omit it in JSTL 1.1/1.2, then things won't work. Also note that you should't use the <code>_rt</code> suffix such as <code>/core_rt</code>, this was the old prototype version.</p> <p>By the way, in <a href="http://download.java.net/maven/1/jstl/jars/jstl-1.2.jar" rel="noreferrer">jstl-1.2.jar</a> the standard.jar is obsolete. If you want, just delete both the jstl and standard JAR's you currently have and use this single JAR instead (yes, just drop in <code>/WEB-INF/lib</code> and anything will go flawlessly).</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.
