To learn the power of Spring/Hibernate, i'm creating a prototype application. This would be an useful application internally if i could provide a nice user interface for this app. Hence I would like to develop a simple web based Client for this app. I've some experience with Struts (Actions/forms) and good knowledge of servlet, but not an expert, as i'm mainly a service side developer.
It would be great if you guys could suggest me to build a client using some existing IDE framework.
