The 'new' (as of 2018) Sling Servlet annotations were presented by Konrad Windszus at adaptTo() 2018. We’ll take a look at three annotations WebServlet, WebFilter, and WebListener that can help us nix our web.xml files. So, the root declaration of your web.xml must look like below (make sure you remove any DOCTYPE from web.xml too, otherwise it will still be interpreted as Servlet 2.3). Registering a Servlet using Java Annotations. In this tutorial, we’re creating a Java web application using Servlet 3.0+. The support for servlet API annotations was only added in Servlet 3.0 (Tomcat 7). JAX-RS is part of JDK, so you don’t need to include anything to use it’s annotations. The mode described on this page slightly improves things by enabling a stricter selection of path-bound servlets, but that's only minor improvements. Ranking, 5105 in MvnRepository (See Top Artifacts). JAX-RS uses annotations to simplify the development and deployment of web services. Java Specifications JSON Libraries JVM Languages Language Runtime Core. This in turn will put the the MyApp.jar at WEB-INF/lib automatically at deployment on server. First, we’ll implement the WebApplicationInitializer interface, then implement the WebMvcConfigurer interface,which allows you to override preset defaults instead of having to specify each particular configuration setting, saving you time and allowing you to work with several tried and true settings out-of-the-box. Java API for RESTful Web Services (JAX-RS) is the Java API for creating REST web services. It appears one also need to add the MyApp.jar to Deployment Assembly of the MyAppWEB project, and not only in Manifest Entries.
