|
| 29 | action or custom action attribute.</p>
|
| 30 | <p>This example uses the &lt;jsp:attribute&gt;
|
| 31 | standard action to use the output of a custom action invocation
|
| 32 | (one that simply outputs "Hello, World!") to set the value of a
|
| 33 | bean property. This would normally require an intermediary
|
| 34 | step, such as using JSTL's &lt;c:set&gt; action.</p>
