Nope .I wanted to get rid of the struts framework and find a easy common validation using a tag library.So I'm Not suing struts framework.I want to write a custom tag library and centralize it to reuse it for all the flied validation of JSP.I use spring web base for the moment but I'm planning to extend to use this custom tag lib in spring modular also in the future.What I'm trying to do here is small text flied where check the length of the input flied and if it's null pop up a message to convey the user.
