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