From Struts in Action:
attribute
(Set to name property)
The name of the request-scope or session-scope attribute that is used to access our ActionForm bean, if it is other than the bean’s specified name. Optional if name is specified, otherwise not valid.

From Programming Jakarta Struts
attribute
The name of the request- or session-scope attribute under which the form bean for this action can be accessed. A value is allowed here only if there is a form bean specified in the name attribute. This attribute is optional and has no default value. If both this attribute and the name attribute contain a value, this attribute will take precedence.

From Struts Kick Start
the attribute attribute enables you to specify a different unique ID to store the ActionForm under the request or session scope; otherwise, the name is used.

Posted by: JasonZhang Posted on: 2003-05-27 22:15 I think it equivalents to the form bean name. If you specify the attribute, the attribute will be used to identify the formbean. You can call request or session object’s method getAttribute(String attribute_name) to retrieve the formbean object.

Posted by: uu_snow Posted on: 2003-05-28 09:15 JasonZhang 在Action的execute的参数中，已经有FormBean了我直接就可以得到formbean object了，何必还有多弄出来一个attribute属性，去用getAttribute 取formbean object呢？
