The Web applications deployed to a Progress Application Server (PAS) instance are generated as Web application archive (WAR) files. When deployed, Web application WAR files are expanded in the server's Java Servlet container (usually the server's /webapps directory.)
In PAS for OpenEdge, the /webapps folder typically includes:
A PAS for OpenEdge ROOT application that replaces the default Tomcat ROOT application. Note that the server must have an application named ROOT installed.
Optional administrative applications.
The ABL Web applications that the application server runs in response to a client request.
A deployed Web application is represented by a Context container in the /conf/server.xml file.
A PAS for OpenEdge ROOT application that replaces the default Tomcat ROOT application. Note that the server must have an application named ROOT installed.
