To expand upon my earlier idea ... petstore src/main/java <-- domain objects and service interfaces go here petstore/petstore-1 <-- specific technology combos petstore/petstore-2
This makes sense, but doesn't scale to cases where a particular demo uses more than one service library of some sort. I'd suggest we put the things like domain object libraries either at the same level as apps, or in the sandbox (since they typically will not have any Shale dependencies). The latter is what I'm planning to do with the MailReader entity classes ... a jar project named "mailreader-jpa" in the sandbox (created locally on my system, but not checked in yet). So you have a petstore.jar artifact produced in the top level module
and petstore-1.war and petstore-2.war in the lower levels. You are reusing the domain and service interfaces across all of the different combo apps. But if one combo uses facelets and another uses clay, we don't really want a whole separate war. Maybe we could have a switch in the maven build where you select your view technology? That might be kind of cool. I'm working on a project with Matt Raible (creator of appfuse) right now so maybe he has some ideas on how to cut down on duplication. Stylesheets and images are another area where we don't want to duplicate things.
If "choose your view technology" means choosing between JSP/Clay/Facelets but always using JSF components, this would be a matter of tweaking config files and swapping out some of the resources. But I worry that the machinery to make this happen would be complex enough and fragile enough to hide the simplicity we're trying to show off. My thinking is we want examples that have "one each" of the technology choices that someone would have to make, and perhaps have part of the docs talk about "if we had chosen xyz instead, we would have done this instead of that." By the way, there is a very nice full featured demo of Clay already (shale-clay-usecases). Sean Craig On 7/19/06, James Mitchell <[EMAIL PROTECTED]> wrote:
