PDFreactor and the application server running the PDFreactor Web Service are Java based, so you need a supported Java VM. The PDFreactor installer (including Web Service) for Windows and macOS already contain a Java VM which will be installed exclusively for PDFreactor. If you are installing PDFreactor on UNIX/Linux you have to install a compatible Java VM suitable for your distribution.

Officially Recommended Java VM for the PDFreactor Library/Web Service:

  • OpenJDK 15

Other Java VMs Supported by the PDFreactor Library/Web Service:

  • Oracle JRE 8

The latest updates and service packs should be installed. We have customers successfully using the product in Oracle or IBM JVMs, but we don't officially test on those platforms.
