I’ve seen others use a customised version of DWR in combination with annotations. We looked at it to the point of almost going with it but in the end the decision was made it wasn’t worth the effort.
We have little in the way of duplication. The approach we took was to be all nice-nice on the JS validation with regards to client feedback and then be more abrupt on the server side as we could assume that if the client side validation failed, either somebody was doing something they shouldn’t be or something had gone wrong in a big way. If server side validation failed on items that JS had supposedly validated we just threw the user to an error page. I like the looks of the JSONValidation Interceptor, but I’m just a little concerned about the number of round trips. It looks like each form submission occurs twice, once for validation via ajax and a second regular HTTP request after. Z. > > @Wes : Thanks for the samples, I'll check it.
