You can install the AppServer Internet Adapter (AIA) when you install the AppServer, or you can install AIA separately on another machine. You must have one of the following installed on the machine where you intend to install the AIA:
A Java container, with HTTPS enabled if you are using Secure Sockets Layer (SSL) connections
A Web server with an integrated Java container, with HTTPS enabled if you are using SSL connections
For more information on AIA installation, see OpenEdge Getting Started: Installation and Configuration.
