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.)
PAS Web applications typically include:
A Progress ROOT application that replaces the default Tomcat ROOT application. Note that the server must have a ROOT application installed.
Optional administrative applications.
Progress applications, such as the "back-end" business logic 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 Progress ROOT application that replaces the default Tomcat ROOT application. Note that the server must have a ROOT application installed.
