Apache Tomcat is an open-source Java Servlet Container that is developed by Apache Software Foundation (ASP). It makes our Java applications run on a server. Apache tomcat is configured on the port 8080. Also, tomcat acts like a development server on your desktop to use for testing building applications that uses servlets/JSP or other Java based dynamic web technologies. EasyApache 4 does not support Tomcat. Tomcat installation is only applicable for the panel that uses EasyApache 3.
