Do I really need web.xml for a Servlet based Java web application?

Question

I haven\'t been working on real world web projects. At university we used both Servlets and Spring for Java web development. In both projects we were given web.xml files alr

Answer 1

No, there will be no need of web.xml for servlet based application if you are using servlet version >3.0 and tomcat 7 as it will not run in the previous versions of tomcat.

Annotation represents the metadata. If you use annotation, deployment descriptor (web.xml file) is not required. Have a look Here for all available annotation.
