text: The generic applet viewer (“applet viewer”) is a Java applet, which can handle various types 
  of documents, such as PDF and Microsoft Office documents (which it renders), images, line 
  data, and AFP documents. The generic applet viewer might be an option if you work with 
  images that are stored in Content Manager OnDemand. 
  
  If you want to avoid the use of Java applets and your content is viewable by browsers (for 
  example, certain image types or textual data), try the browser pass-through viewer, which lets 
  the browser handle the data natively. If you work with AFP and must use the AFP browser 
  plug-in, register the Content Navigator plug-in, AFPViewerPlugin.jar, and configure the 
  viewer map that is assigned to your Content Navigator desktop to use the AFP viewer for the 
  application/afp MIME type. The AFPViewerPlugin.jar file ships with Content Navigator. You 
  must choose the web browser pass-through viewer. 
  
  The Ajax viewer is a Web 2.0 JavaScript application that provides basic document functions, 
  such as page-wise browsing, rotation, or zoom. It is not a Java applet.
