Quickest way I found was to cut and paste the code from DispatchAction source into my own class that extended my base class instead of action, then I extend my DispatchActions from that. The disadvantage is that if you upgrade to a new version of struts you need to remember to update your base dispatch action class.
Nowdays though i prefer not to use dispatch actions, but rather hardcode an if statement to check the parameter in my execute and branch on that. Its a little more typing, but I find it gives more control and is more convienient in other ways. -----Original Message----- From: Pat Quinn [mailto:[EMAIL PROTECTED] Sent: Thursday, 18 September 2003 18:09 To: [EMAIL PROTECTED] Subject: Re: Template Method Design Take a look at Chapter 10 - Exception Handling in Programming Jakarta Struts by chuck cavaness.. i think you'll find this very helpful.
