<h1>JSP
Samples</h1>
<p>This is a collection of samples demonstrating the usage of different
parts of the Java Server Pages (JSP) specification. Both JSP 2.0 and
JSP 1.2 examples are presented below.
<p>These examples will only work when these pages are being served by a
servlet engine; of course, we recommend
<a href="https://tomcat.apache.org/">Tomcat</a>.
They will not work if you are viewing these pages via a
"file://..." URL.
<p>To navigate your way through the examples, the following icons will
help:</p>
<ul style="list-style-type: none; padding-left: 0;">
<li><img src="images/execute.gif" alt=""> Execute the example</li>
<li><img src="images/code.gif" alt=""> Look at the source code for the example</li>
<li><img src="images/return.gif" alt=""> Return to this screen</li>
</ul>
<p>Tip: For session scoped beans to work, the cookies must be enabled.
This can be done using browser options.</p>

are formed by grouping together multiple EL expressions. Each of them is
evaluated from left to right, coerced to String, all those strings are
concatenated, and the result is coerced to the expected type.

<h1>JSP 2.0 Expression Language - Implicit Objects</h1>
<hr>
This example illustrates some of the implicit objects available
in the Expression Language. The following implicit objects are
available (not all illustrated here):
<ul>
<li>pageContext - the PageContext object</li>
<li>pageScope - a Map that maps page-scoped attribute names to
their values</li>
<li>requestScope - a Map that maps request-scoped attribute names
to their values</li>
<li>sessionScope - a Map that maps session-scoped attribute names
to their values</li>
<li>applicationScope - a Map that maps application-scoped attribute
names to their values</li>
<li>param - a Map that maps parameter names to a single String
parameter value</li>
<li>paramValues - a Map that maps parameter names to a String[] of
all values for that parameter</li>
<li>header - a Map that maps header names to a single String
header value</li>
<li>headerValues - a Map that maps header names to a String[] of
all values for that header</li>
<li>initParam - a Map that maps context initialization parameter
names to their String parameter value</li>
<li>cookie - a Map that maps cookie names to a single Cookie object.</li>
</ul>
<blockquote>
<u><b>Change Parameter</b></u>
<form action="implicit-objects.jsp" method="GET">
foo = <input type="text" name="foo" value="${fn:escapeXml(param["foo"])}">

<title>JSP 2.0 Examples - Shuffle Example</title>
</head>
<body>
<h1>JSP 2.0 Examples - Shuffle Example</h1>
<hr>
<p>Try reloading the page a few times. Both the rows and the columns
are shuffled and appear different each time.</p>
<p>Here's how the code works. The SimpleTag handler called
&lt;my:shuffle&gt; accepts three attributes. Each attribute is a
JSP Fragment, meaning it is a fragment of JSP code that can be
dynamically executed by the shuffle tag handler on demand. The
shuffle tag handler executes the three fragments in a random order.
To shuffle both the rows and the columns, the shuffle tag is used
with itself as a parameter.</p>

&lt;title>JSP 2.0 Examples - Shuffle Example&lt;/title>
&lt;/head>
&lt;body>
&lt;h1>JSP 2.0 Examples - Shuffle Example&lt;/h1>
&lt;hr>
&lt;p>Try reloading the page a few times. Both the rows and the columns
are shuffled and appear different each time.&lt;/p>
&lt;p>Here's how the code works. The SimpleTag handler called
&amp;lt;my:shuffle&amp;gt; accepts three attributes. Each attribute is a
JSP Fragment, meaning it is a fragment of JSP code that can be
dynamically executed by the shuffle tag handler on demand. The
shuffle tag handler executes the three fragments in a random order.
To shuffle both the rows and the columns, the shuffle tag is used
with itself as a parameter.&lt;/p>
&lt;hr>
&lt;blockquote>
&lt;font color="#ffffff">
&lt;table>
&lt;my:shuffle>
&lt;jsp:attribute name="fragment1">

<h1>JSPX - XHTML Basic Example</h1>
This example illustrates how to use JSPX to produce an XHTML basic
document suitable for use with mobile phones, televisions,
PDAs, vending machines, pagers, car navigation systems,
mobile game machines, digital book readers, smart watches, etc.
<p/>
JSPX lets you create dynamic documents in a pure XML syntax compatible
with existing XML tools. The XML syntax in JSP 1.2 was awkward and
required &amp;lt;jsp:root&amp;gt; to be the root element of the document.
This is no longer the case in JSP 2.0.
<p/>
This particular example uses
namespace declarations to make the output of this page a valid XHTML
document.
<p/>
Just to prove this is live, here's some dynamic content:
<jsp:useBean id="now" class="java.util.Date" />
<fmt:formatDate value="${now}" pattern="MMMM d, yyyy, H:mm:ss"/>

<title>JSP 2.0 SVG Example</title>
</head>
<body>
<h1>JSP 2.0 SVG Example</h1>
This example uses JSP 2.0's new, simplified JSPX syntax to render a
Scalable Vector Graphics (SVG) document. When you view the source,
notice the lack of a &lt;jsp:root&gt; element! The text to be rendered
can be modified by changing the value of the name parameter.
<p>
SVG has many potential uses, such as searchable images, or images
customized with the name of your site's visitor (e.g. a "Susan's Store"
tab image). JSPX is a natural fit for generating dynamic XML content
such as SVG.
<p>
To execute this example you will need a browser with basic SVG support. Any
remotely recent browser should have this.
<ol>
<li>Use this URL:
<a href="textRotate.jspx?name=JSPX">textRotate.jspx?name=JSPX</a></li>
<li>Customize by changing the name=JSPX parameter</li>
</ol>
<p style="margin-top: 2em;">
The following is a screenshot of the resulting image, for those using a
browser without SVG support:<br>
<img src="textRotate.jpg" alt="[Screenshot image]" style="border: 1px solid #000;">

&lt;h1>JSP 2.0 Examples - JSP Configuration&lt;/h1>
&lt;hr>
&lt;p>Using a &amp;lt;jsp-property-group&amp;gt; element in the web.xml
deployment descriptor, this JSP page has been configured in the
following ways:&lt;/p>
&lt;ul>
&lt;li>Uses &amp;lt;include-prelude&amp;gt; to include the top banner.&lt;/li>
&lt;li>Uses &amp;lt;include-coda&amp;gt; to include the bottom banner.&lt;/li>
&lt;li>Uses &amp;lt;scripting-invalid&amp;gt; true to disable
&amp;lt;% scripting %&amp;gt; elements&lt;/li>
&lt;li>Uses &amp;lt;el-ignored&amp;gt; true to disable ${EL} elements&lt;/li>
&lt;li>Uses &amp;lt;page-encoding&amp;gt; ISO-8859-1 to set the page encoding (though this is the default anyway)&lt;/li>
&lt;/ul>
There are various other configuration options that can be used.
