This tag enables developers to call actions directly from a JSP page by specifying the action name and an optional namespace.

• name* (String) - name of the action to be executed (without the extension suffix eg. .action)
• namespace (String) - default to the namespace where this action tag is invoked
• executeResult (Boolean) - default is false. Decides wheather the result of this action is to be executed or not
• ignoreContextParams (Boolean) - default to false. Decides wheather the request parameters are to be included when the action is invoked
