Instantiates a class that conforms to the JavaBeans specification. This tag has a body which can contain
a number of
Param elements to set any mutator methods on that class.
If the id attribute is set on the BeanTag, it will place the instantiated bean into the
stack's Context.
- id - the stack's context id (if supplied) that the created bean will be store under
- name* - the class name of the bean to be instantiated (must respect JavaBean specification)
Examples:
<-- in freemarker form -->
[@s.bean name="org.apache.struts2.example.counter.SimpleCounter" id="counter"]
[s:param name="foo" value="BAR"/]
The value of foo is : [s:property value="foo"/], when inside the bean tag.
[/s:bean]
<-- in jsp form -->
<s:bean name="org.apache.struts2.example.counter.SimpleCounter" id="counter">
<s:param name="foo" value="BAR" />
The value of foot is : <s:property value="foo"/>, when inside the bean tag <br />
</s:bean>
This example instantiates a bean called SimpleCounter and sets the foo property (setFoo('BAR')). The
SimpleCounter object is then pushed onto the Valuestack, which means that we can call its accessor methods (getFoo())
with the Property tag and get their values.
In the above example, the id has been set to a value of counter. This means that the SimpleCounter class
will be placed into the stack's context. You can access the SimpleCounter class using a Struts tag:
<-- jsp form -->
<s:property value="#counter" />
<-- freemarker form -->
[s:property value="#counter.foo"/]
In the property tag example, the # tells Ognl to search the context for the SimpleCounter class which has
an id(key) of counter
