Tag Name: <a2:action />

Description

Execute an action from within a view

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 xwork.xml will be ignored, unless the executeResult parameter is specified.

id (String) - the id (if specified) to put the action under stack's context.
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

  public class ActionTagAction extends ActionSupport { public String execute() throws Exception { return "done"; } public String doDefault() throws Exception { ServletActionContext.getRequest().setAttribute("stringByAction", "This is a String put in by the action's doDefault()"); return "done"; } }

   ....  success.jsp   success.jsp  ....

  The following action tag will execute result and include it in this page
 
  
 The following action tag will do the same as above, but invokes method specialMethod in action
