|---|
| 25 | <hr> |
|---|
| 26 | <p>The new <jsp:attribute> and <jsp:body> |
|---|
| 27 | standard actions can be used to specify the value of any standard |
|---|
| 28 | action or custom action attribute.</p> |
|---|
| 29 | <p>This example uses the <jsp:attribute> |
|---|
| 30 | standard action to use the output of a custom action invocation |
|---|
| 31 | (one that simply outputs "Hello, World!") to set the value of a |
|---|
| 32 | bean property. This would normally require an intermediary |
|---|
| 33 | step, such as using JSTL's <c:set> action.</p> |
|---|

| 35 | <jsp:useBean id="foo" class="jsp2.examples.FooBean"> |
|---|
| 36 | Bean created! Setting foo.bar...<br> |
|---|
| 37 | <jsp:setProperty name="foo" property="bar"> |
|---|
| 38 | <jsp:attribute name="value"> |
|---|
| 39 | <my:helloWorld/> |
|---|
| 40 | </jsp:attribute> |
|---|
| 41 | </jsp:setProperty> |
|---|
| 42 | </jsp:useBean> |
