| <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> |
