Apache Tomcat Server is an open source web server used for the deployment of Java based Web applications using Java Servlet and JavaServer Pages technologies. The Java Servlet and JavaServer Pages specifications are developed by Sun under the Java Community Process. Web Servers like Apache Tomcat support only web components.
