I want to extend functions of dispatchAction class, like i want a class which extends DispatchAction and overrides the execute method, But keep all the existing functions,
But if i override the execute method, then i will have to code the same function available in origianl DispatchAction, and add my extra functions, ( like cut and paste the code) but then if in future DispatchAction is modified i will need to modify my class.
or have one class which will have all the functions of DispatchAction , but also want to add more functions.
What i have done in MyActionClass is
public abstract class MyAction extends Action
public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request,
HttpServletResponse response)
throws Exception
//common code for all action classes
CommonClass cc = new CommonClass();
// just sample method
return performTask(mapping, form, request, response);
// this is the method which will be implemented by each overriding class and add the necessary logic
protected abstract ActionForward performTask(ActionMapping mapping, ActionForm form, HttpServletRequest request,
HttpServletResponse response)
throws Exception;
I have a CommonClass for doing all the common function,
How can i do it DispatchAction
