Servlets are designed to run inside a servlet container (eg. Apache Tomcat). Execution of a servlet happens in the following manner: The servlet container calls the
GenericServlet.service()method on a servlet which typically calls the appropriatedoXxx()method, eg.doGet(),doPost(), etc. ThedoXxx()method is responsible for interpreting the HTTP request and serving an appropriate response.GenericServlet.service()is roughly analagous tomain()in a plain old java class.
