Application Platform uses Software AG Web Server, which is based on Apache Tomcat. The Software AG Web Server is part of Software AG Common Platform. Integration Server, on the other hand, provides its own Tomcat instance via the WmTomcat package. The WmTomcat package must be disabled in servers that host Application Platform web modules. By default, the WmTomcat package is disabled when you first install Integration Server and when you create Integration Server instances by using the is_instance.sh/bat script. If the WmTomcat package is enabled on the Integration Server where you want to publish your Application Platform projects, follow the steps in this procedure.
