| <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> | |
