I'm working on a project where we faced a similar situation. We don�t have as many pages as you, but nonetheless. Here�s what we have done, maybe there�s some ideas in here for you.
We built two builder classes that contain a single static method in each (FormBuilder and ViewBuilder). We are using DynaValidatorForm�s and the action classes call the business tier and get back a view hierarchy of some sort. We pass this view into the FormBuilder by calling a populateForm() method. The FormBuilder populates the Map with the view�s attributes and any referenced views it knows about. We are using a nested notation as the keys, to prevent collisions. So, if this is the view hierarchy: UserView � addressView And supposed addressView has a property called firstName, the key in the map for this value is: AddressView.firstName After the DynaActionForm is populated, everything else works the same to display the JSP page. The property names in the JSP tags have to use the nested notation to access properties in sub views, but that�s OK. When the client submits the HTML, the DynaActionForm is populated as usual, using the property names. The Action class calls the method populateView() and passes in the DynaActionForm and the top-level view bean and the builder does a reversal and builds the view hierarchy back. >From there, the action invokes the business tier and so on. It seems to work pretty well for us, but maybe not for everybody. Timestamps, Enumerated types, and collections are a little tricky to deal with, but they can be done in a similar manner. I�m obviously leaving a few details out, but you get the point. Here are some decisions that we�ve made in order for this to work: - The DynaActionForm only deals with Strings - All business logic validation occurs in the business tier - Input validation is taken care because we are using the ValidatorActionForm Hope that helps, Chuck > Subject: ActionForm Design Thoughts.. > From: "Anand Jayaraman" <[EMAIL PROTECTED]> > === > Hi All, > > I am designing a Application and would like to get inputs from some > experienced ones out there. > > 1) I will be have close to 100 JSP pages and I dont want to write a > ActionForm for everything. > 2) I would like to design a generic one.
