| 25 | <h1>JSP 2.0 Examples - Shuffle Example</h1> |
|---|
| 26 | <hr> |
|---|
| 27 | <p>Try reloading the page a few times. Both the rows and the columns |
|---|
| 28 | are shuffled and appear different each time.</p> |
|---|
| 29 | <p>Here's how the code works. The SimpleTag handler called |
|---|
| 30 | &lt;my:shuffle&gt; accepts three attributes. Each attribute is a |
|---|
| 31 | JSP Fragment, meaning it is a fragment of JSP code that can be |
|---|
| 32 | dynamically executed by the shuffle tag handler on demand. The |
|---|
| 33 | shuffle tag handler executes the three fragments in a random order. |
|---|
| 34 | To shuffle both the rows and the columns, the shuffle tag is used |
|---|
| 35 | with itself as a parameter.</p> |
