Class Set
java.lang.Object
 com.opensymphony.webwork.components.Component
com.opensymphony.webwork.components.Set
public class Set - extends Component
The set tag assigns a value to a variable in a specified scope. It is useful when you wish to assign a variable to a
complex expression and then simply reference that variable each time rather than the complex expression. This is
useful in both cases: when the complex expression takes time (performance improvement) or is hard to read (code
readability improvement).
Parameters
- name* (String): The name of the new variable that is assigned the value of value
- value (Object): The value that is assigned to the variable named name
- scope (String): The scope in which to assign the variable. Can be application, session,
request, page, or action. By default it is action.
Examples
<ww:set name="personName" value="person.name"/>
Hello, <ww:property value="#personName"/>. How are you?
