<p>
The <a href="http://jakarta.apache.org/slide/";>Jakarta Slide</a>
project
includes JSP tag libraries to support the creation of web-based
presentation layers accessing and displaying content stored in Slide
repositories.
</p>
<p>
To keep the tag library code lean, we have to decided to rely on
existing
tag libraries to support basic functionality like iteration and
conditionals. Two such libraries are currently supported:
<b>Struts 1.x</b> and the <b>JSP Standard Tag Library (JSTL) Early
Access</b> releases. The Slide Tag Library cannot effectively be used
on
its own, but requires one of the above fundamental libraries.
</p>
<p>
The following examples demonstrate the features of the Slide tag
library,
and its integration with the tag library providing the common
functionality.

<p>
This variant of the Slide tag library is based on
<a href="http://www.jcp.org/jsr/detail/52.jsp";>JSR-052</a>, the
JSP Standard Tag Library (JSTL). You can get the early access
releases of the reference implementation at
<a href="http://jakarta.apache.org/taglibs/";>Jakarta Taglibs</a>.
Please note that JSTL requires a Java Sevrlet 2.3 and JSP 1.2
compliant servlet container (like
<a href="http://jakarta.apache.org/tomcat/";>Tomcat 4</a>).
</p>
<p>
You will need to provide a couple of libraries by copying them
to the <code>WEB-INF/lib</code> directory of this web-app:
<br><br>
<table border="0" cellpadding="5" cellspacing="0">
<tr>
<td><code>js.jar</code></td>
<td>
<a href="http://www.mozilla.org/rhino/";>Mozilla
Rhino</a> -
A Java implementation of JavaScript/ECMAScript.
</td>
</tr>
<tr>
<td><code>jaxen-full.jar</code></td>
<td>
<a href="http://jaxen.org/";>Jaxen</a> -
The XPath engine used by the JSTL XML tag library.
</td>
</tr>
<tr>
<td><code>saxpath.jar</code></td>
<td>
<a href="http://saxpath.org/";>SAXPath</a> -
XPath API used by Jaxen.
</td>
</tr>
</table>
</p>
<p>
You'll also need a JAXP-based XML-Parser and XSLT-Processor to
run some of the examples (see
<a href="http://xml.apache.org/";>The Apache XML Project</a> for
distributions of Xerces and Xalan).
Apart from those, the JAR files <code>standard.jar</code>,
<code>slide-taglib-common.jar</code> and
<code>slide-taglib-jstl.jar</code> should be already included
in this web-app.

<h1>Slide/JSTL Tag Library Example</h1>
<p>
This example uses the JSTL core and xml tag libraries in conjunction with
the <code><slide:content></code> tag. A web.xml file is retrieved
from the Slide repository, parsed and the main servlet-related definitions
pretty-printed as HTML.
</p>

Enter location of a web.xml file in the Slide namespace:<br>

value="$params.uri[0]" default=""/>'/>
</core:when>
<core:otherwise>
<input name='uri' type='text' size='80' value='/files/WEB-INF/web.xml'/>
</core:otherwise>
</core:choose>
<input type='submit'>
<input type='reset'>
