Thanks, this is the best explanation I've read so far on switching modules.
One issue I have with this. In my applications I always have an application specific BaseAction that all of my Action classes extend from. This is to enforce my business rules on every request. I do not use generic/predefined Actions. When I have found the need for the functionality of the predefined actions (Success, Dispatch, Switch, etc) I've reimplemented them so they extend my BaseAction. What I would like to see, and this is targeted to the community in general, is a way to use these generic behaviors without having to bypass my BaseAction or reimplement them. Maybe as helper classes that I call from my actions. There are several ways to solve this and I just thought I should put it out there to see if others have experienced the same issues and have some other solutions. > -----Original Message----- > From: Srikanth Shenoy [mailto:[EMAIL PROTECTED] > Sent: Thursday, March 11, 2004 7:30 PM > To: [EMAIL PROTECTED] > Subject: Re: help implementing modules... > > Hi Gary, > > I would suggest download the following free chapter from my book - > Struts Survival Guide. > Go to http://www.objectsource.com and find the link there to download > Chapter 4. > It tells you how to setup and use modules. > > Hope that helps, > > Srikanth Shenoy > Author > Struts Survival Guide: Basics to Best Practices > <http://www.objectsource.com/strutsbook.html> > J2EE Project Survival Guide > <http://www.theserverside.com/books/review/J2EESurvivalGuide.tss> > > > "Damm, Gary" <[EMAIL PROTECTED]> wrote in message > news:<[EMAIL PROTECTED]>... > I've successfully used Struts for several applications and have been > very happy with it.
