IBM® Content Navigator works with several types of viewers. The IBM Content Navigator administration tool includes a default viewer map that specifies which viewer is used to open each file type.
A viewer map defines which MIME types are associated with each viewer that you want to use. For example, if you want to use the Applet viewer for a desktop, you associate it with the MIME type ANY. You then can add the back up viewers to use, such as Ajax or HTML, if the JRE failed. You can create multiple viewer maps if you want to use different viewers for different desktops, then go to any existing desktop and select a viewer map on that desktop.
The order in which you list viewer in your viewer map is important. The order determines which viewer is the fallback viewer if a mapping does not work.
You cannot edit the default viewer map. However, you can create a custom viewer map if you want to use different viewers or add file types to the mapping. You can associate only one viewer map with each desktop in your environment. If you create a viewer map, you must create a desktop to use that viewer map.
If you are creating a custom viewer, the viewer must be integrated as a plug-in before you can add it to the viewer map.
