One of the other interesting things on devoxx is the presentation of the coming JCP release for Servlet Spec 3.0.
A short list of changes.
A great addition to Servlets is modularization. Not everything needs to be defined in one web.xml file. But different modules/parts of an application can now have different fragmented
web.xml. In the same time there will be support for Annotations that can define stuff you would normally define the in web.xml file.
e.g.
@WebServlet (value=”/shoppingcart”)
