Deploying a Java Project on Tom Cat

I have a java project (not a web application, no web.xml etc) I need to deploy it as a WAR on a tomcat with init servlet. Can anyone help me with the steps to do the same?

Any project that is to be deployed to a Java web container, despite that it does not have any web front-end i.e webservice, EJB3 project, needs to have a web.xml. Map your servlet in web.xml and then package the project as war file and it is as easy as dropping it to $CATALINA_HOME/webapps.
