NOTE - The JDK and JRE are not distributed with isCOBOL Evolve. They must be installed before using isCOBOL Evolve. For most platforms, they can be downloaded free of charge from “http://www.oracle.com/technetwork/java/javase/downloads/index.html”. For more information, refer to the installation section.

The minimum Java version required is 1.7. Previous versions are not supported.

The JDK contains the Java compiler, utilities and a copy of the JRE.

On Microsoft Windows® platforms, the JDK and JRE are installed in subdirectories of “C:\Program Files\Java”. For example, the default installation directory for JDK 7 is “C:\Program Files\Java\jdk1.7.0”.

The default installation directory for the JRE that comes with JDK 7 is “C:\Program Files\Java\jdk1.7.0\jre”.

The JRE is distributed separately for production-only sites where no development kit is needed. The default installation directory for JRE 7 is “C:\Program Files\Java\jre1.7.0”.
