<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
<my:shuffle> 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>
