- <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>
