Apache Tomcat is an open-source implementation of the Java Servlet, JavaServer Pages (JSP), Java Expression Language, and Java WebSocket technologies. It provides a pure Java HTTP web server and servlet container for hosting Java web applications. Tomcat exposes management APIs via the Manager application (HTTP text protocol), JMX for monitoring, and a Virtual Host Manager for configuration management. It is maintained by the Apache Software Foundation and is one of the most widely deployed Java application servers.
