Yes, delegation is the common alternative for multiple inheritance. If you are using IntelliJ, you can use the Code / Delegate Methods menu option. It will write the methods for you :)

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]
