Java Servlet
A Java Servlet is a Java object that responds to HTTP requests. It runs inside a Servlet container.
A Servlet is part of a Java web application. A Servlet container may run multiple web applications at the same time, each having multiple servlets running inside.
A Java web application can contain other components than servlets. It can also contain Java Server Pages (JSP), Java Server Faces (JSF) and Web Services. This tutorial is about Java Servlets only, though.
