This document provides instructions for automatically deploying a Java application to Tomcat using Jenkins. It involves: 1) Creating a Tomcat manager-gui and manager-script user, 2) Configuring Maven settings.xml for Tomcat deployment, and 3) Adding the Tomcat Maven plugin to the project's pom.xml to define the deployment settings. Once configured, Jenkins can be set up to build and deploy the application to Tomcat with the tomcat7:undeploy and tomcat7:deploy goals.
