Thanks Daniel. I'll try to look at this w/in the next week. My goal is to convert an existing Struts app to use Spring's MVC framework with minimal changes. So far, I've got Struts Menu, the DisplayTag and Tiles working. All were pretty trivial. Next up - Action to Controller and Validation. I'm using XDoclet pretty heavily in my existing app - so I'm somewhat motivated to continue generating validation.xml from POJOs. I'll probably have to hack XDoclet to make this work - since it only works for ValidatorForms right now. Of course, after looking at the attributes stuff, they might actually be easier to use than XDoclet. The one advantage of XDoclet, however, is that the XML files are still generated, so stuff can be changed after compilation. As far as I understand the attributes stuff - it'll stay hardcoded in your class (no XML generation). Of course, I rarely change any of this stuff after compilation - but it is a nice option.
