Thank you for quick reply Michael.
Yes I am talking about Struts Dialogs.
So I guess service layer calls should be made from WizardNode validate
method.
I see how you integrate rule engine with struts in your second article.
Struts Dialog looks really cool.

Hi All
I have look at struts dialog to implement wizard kind of screen flow. I
looks good. (took some time to understand that too).
Right... I know that current version is... er... overengineered. The
new version will be much simpler.
I have two questions?
1. If I have to make some calls to service layer to validate data
entered , where do I make that call?
I assume that you are indeed talking about Struts Dialogs, not about
Shale Dialogs. In the wizard solution that is used in Struts Dialogs
validation is the integral part of the wizard flow. Depending on
validity of a particular transition wizard decides what the next step
will be. This is used to create non-linear wizards where you can skip
one or several steps depending on a certain condition.
Therefore validation should be performed by the wizard, not by an ActionForm.
2. How scable is this solution?? My estimate is about 100 users at a
time on webspere.
No scalability tests were done, but I would say that 100 users is not a lot.
Michael.
