问题 I have an ExtJS application and some different environments (local machine, development, production-like test environment, and production). The ExtJS application is backed by a Java backend which is also running on either a local machine, in a development environment, a production-like test environment or a production environment (not the same servers as where the front end application lives though). For the last two environments, I want to build ONE build of the ExtJS app and first deploy it

问题 I have got a particular requirement where some critical algorithms have to be handled in the client-side script and it got to be secured. Using javascript will just expose the algorithm. I am currently evaluating ways to secure the algorithm on the client script. Appreciate any suggestions and alternative approaches.

问题 A few years ago client Java was unsuitable for web development because a remarkable part of web users did not have Java installed. ( I don't remember exact numbers, more than 10%). Now I see the Google Analytics stats for a big site and it tells that >98% of users have Java installed. Is these stats very biased by Javascript usage?

问题 Each form in the application has a set of radiobuttons. Once selected, only certain fields associated with that radiobutton will need to be validated. I am using MVC 3 and need the validation to work client side. Simply using DataAnnotations I can only validate all fields on the form. IValidatableObject doesn't work clientside.
