I have some confusion about which one is good JSF or GWT. both are at their own best but I find that for GWT there is no drag & drop thing for designing purposes. instead of I am using NetBeans in which for JSF there is drag and drop available for all designing components.
so which technology is best to learn and use in the project.
There's also a Drag and Drop IDE for GWT - however, this wouldn't be a deciding factor for me in what toolkit to choose - drag and drop builders are usually good for nothing other than quick prototypes of layout and brainstorming - especially for web apps. I'd use something like Balsimiq or DENIM that is only a visual tool.
