In PAS for OpenEdge, the default ROOT application is a deployment of oeabl.war, the OpenEdge Web application. The OpenEdge Web application is a type of Java Web application that is preconfigured, with security and Java Servlet interfaces that translate HTTP client requests into ABL requests and schedules their execution using the ABL Session Manager.
Note: The standard Tomcat configuration files and applications (like ROOT.war) are preserved in $CATALINA_HOME/extras.
