A JDK must be installed on your machine in order to use the Veryant isCOBOL extension. For best results and performance, install the latest JDK version available for your platform. isCOBOL is certified to work correctly with both Oracle JDK and OpenJDK from version 8 to version 21.

Note - Using Java 21 the default encoding is UTF-8 on every operating system.

Self-extracting setups are provided for the Windows platform.

On Unix/Linux platforms Java may be already installed. If it’s not the case, you can install it using the appropriate system commands (e.g. yum, or apt-get).
