Hey, I could really be missing the point and I haven't had time to delve into the struts/validator code. To me, it sounds like you might want to look into dynamically building a validator action (or whatever object is defined in the validation.xml) and map that to your form. If your jsp then has the client-side validator tags, you will get client-side validation. You will also get server-side validation if you have validation turned on. I have not looked into doing this, but with my limited knowledge of struts, it seems feasible. To summarize, I suggest that you dynamically build what normally would be defined in validation.xml in struts1.1.

Do you mean to use the validator "outside" struts (in the business layer) and delegate all validations in the form to the business object? Like this: MyForm extends ActionForm { .. public ActionErrors validate(..) { ... Questionnaire->validate(); ... } } That was my first idea, too. But in this case I don't know how to use client side validation (and that's a really nice feature). And it still doesn't solve the problem of dynamically created questionnaires/forms. I'm thinking about a way to extend/modify the validator for supporting "runtime configuration". I hope that this is not too complicate - I guess that I only have to exchange the digester creation by a runtime configuration. Or by simply "extending" the digester for creating my own "business" classes, adding some features which I require, and add the ability to the business classes (or add a layer between with this ability) to generate the validator framework classes on the fly, based on the extended definition.
