WebAccess, the Calendar Publishing Host, and Monitor rely on the presence of a Web server in order to fulfil their functions. A number of Web servers are supported. See GroupWise System Requirements
in Installing a Basic GroupWise System
in the GroupWise 2012 Installation Guide.
On Linux, the GroupWise Web applications are installed into the Apache Web server and the Tomcat Java Servlet Container. On Windows, the GroupWise Web applications are installed into the Internet Information Server (IIS) and the Tomcat Java Servlet Container. On both platforms, configuration files, log files, and working files, are stored in a separate directory outside of your Web server and Tomcat installations.
