Java must be installed on your machine in order to use isCOBOL Server. For best results and performance, install the latest Java version available for your platform. isCOBOL Server is certified to work correctly with both Oracle JDK and OpenJDK from version 8 to version 17.

A JRE (Java Runtime Environment) is enough to run isCOBOL Server, however a JDK (Java Development Kit) is suggested in order to take advantage of advanced monitoring features.

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).
