The web server that is supported for your operating system, for use with the GroupWise Administration console, the agent consoles, WebAccess, Monitor, and the Calendar Publishing Host:

A Linux repository should be available when you run the GroupWise Installation Wizard. Apache, Tomcat, the JRE or JDK, and the ModProxy Module are automatically installed from the Linux repository if they are not already present on the Linux server.
If no Linux repository is available during the GroupWise installation, you are prompted to manually install these required components from the Linux media, and then restart the GroupWise installation.
Windows Server 2012 R2 or Windows Server 2016
Microsoft Internet Information Server (IIS) 7 or later plus:
Tomcat 7
Oracle Java 6 Runtime Environment (JRE) or later

Tomcat, Oracle JRE, and Jakarta Connector are automatically installed along with the GroupWise software if they are not already present on the Windows server.
ISAPI support
ISAPI support is no longer installed by default when you install Windows Server 2008 R2 or later and Internet Information Services (IIS). If ISAPI support was not manually selected when IIS was installed, you can add it after the fact. See Section F.0, ISAPI Configuration.
