3.3 About Tomcat Manager
Tomcat Manager is a browser-based administration tool you can use for installing and deploying Web applications.
HINT:Web application is a term used to describe two or more servlets and JSPs, or a combination of both, working together to provide a set of end-user functions or services. However, Web application is also often used synonymously with servlet.
