Description
This tag enables developers to call actions directly from a JSP page by specifying the action name and an optional namespace. The body content of the tag is used to render the results from the Action. Any result processor defined for this action in struts.xml will be ignored, unless the executeResult parameter is specified.
Parameters can be passed to the action using nested param tags.
Placement in context
The action will not be published to the context until the whole tag is evaluated, meaning that inside the body of the tag, the action cannot be accessed, For example:
Will print:
Is "myAction" null inside the tag? true
Is "myAction" null outside the tag? false
