Apache Tomcat

aid: apache-tomcat
name: Apache Tomcat
description: 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.
