Thumbnail Plug-ins are based on Java classes and enable the generation of preview images for objects of certain MIME types.

 

Integration

  • On UNIX system, the following entry is listed for the headless mode in the Java VM settings:

    You make this setting in the SAP AS Java Engine Config Tool (see SAP Note 710146).
