Hi Navjot, I never said that these helper classes are not required..Infact I am using them heavily in my application..
What i am saying is U need not extend those acions or copy thier code in your base action....BEcause that does not serve any purpose.. U can use the dispatch action as it is... regards, Shirish -----Original Message----- From: Navjot Singh [mailto:[EMAIL PROTECTED] Sent: Monday, March 31, 2003 3:23 PM To: Struts Users Mailing List Subject: Re: Design Problem Action Class hi shirish, SAY We write 2 methods in Action (MUST extend DynamicAction here) Class public ActionForward add(...) public ActionForward del(...) AND we have action tag in config file saying <action type=".." parameter="param" > Calling URLs a.do?param=add a.do?param=del will directly call those methods. AND there by save 2 IFs in execute(...) method :-) Hope now you would agree THIS Helper Action class is really useful ;-) regards Navjot Singh ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, March 31, 2003 6:36 PM Subject: RE: Design Problem Action Class But I dont get the point of extending those Helper Actions... Becasue those helper classes will never fulfill a request on thier own..So ultimately whtever is the application logic in your base action(Like login check etc..)will be executed as the call finally goes to some Other applicationAction... And Also I am not sure what u mean by delegation here..But beware...If u mean caling one action which does all of this from all other actions, it is stringly discouraged in struts..Use of Actions as APIs is strongly discouraged.. -----Original Message----- From: Dario Geier [mailto:[EMAIL PROTECTED] Sent: Monday, March 31, 2003 2:56 PM To: Struts Users Mailing List Subject: RE: Design Problem Action Class I am having the same problem shortly. I am thinking of the following solution: First, you'll need to inherit from all the action type classes you'll need in your application. Action DispatchAction SwitchAction Y Y Y MyAction MyDispatchAction MySwitchAction >From this custom layer, use delegation to call common to all actions functionality. Then, you write this functionality just once, and it is "actiontype independent". -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, March 31, 2003 3:35 PM To: [EMAIL PROTECTED] Subject: RE: Design Problem Action Class I had faced simalr problem.. We have our own AbstractAction and other action hierarchy..And i still wabnted to use the action classes from Scaffold package(FindForward action etc..) But what I have done is I am using those action classes as they are,they do not belong to my applications action hierarchy..And that makes sense.. BEcause most of those action classes are utility classes .So they do not belong to your applications action hierarchy.And even if they do not extend from the AbstractAction of u r appliaction, u will not have any problem.BEcause they are necven called directly.They are used some where in the application flow as utility classes. hope this helps, Shirish -----Original Message----- From: Navjot Singh [mailto:[EMAIL PROTECTED] Sent: Monday, March 31, 2003 2:28 PM To: Struts Users List Subject: Design Problem Action Class Hi geeks, I have class hierarchy like this. CustomerAction Y AppAction Y Action Now that i have seen DisapatchAction, I wish to use it for my further actionclasses. BUT the problem is DispatchAction extends Action. One way i can think of is to change AppAction to start extending DisptachAction. BUT all of my classes don't need the functionality of DisptachAction. Just a few need this functionality. How can I go about it? regards Navjot Singh --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
