Using JSP, is the deployment descriptor (web.xml) obsolete?

I should preface this question by saying that I am new to JavaServer Pages. I have been researching the purpose and use of the deployment descriptor (commonly referred to as web.xml). I found this document which says that some Java annotations can be used to describe things that would typically be put in the deployment descriptor. So, my question is:

  1. Using the latest version of JSP, is it possible to only use annotations to describe what would otherwise go in the deployment descriptor?

That is sort of the point. Rather than using web.xml, you would annotate your classes that fulfill those various functions. A Servlet would be annotated with @WebServlet, a Filter with @WebFilter, etc.

Here's a good article: http://www.servletworld.com/servlet-tutorials/servlet3/new-features.html

Note that this is a common trend in Java EE - the move away from XML configuration to annotations. Spring, for example, is following this trend with the v3.1 introduction of @Configuration classes which can take the place of XML config files.
