Download and install the Java Development Kit (JDK)

JDK version 1.6 (or later) from Oracle must be installed on your machine in order to use isCOBOL products. For best results and performance, install the latest JDK version available for your platform.

1.	Go to "http://www.oracle.com/technetwork/java/javase/downloads/index.html".

2.	Click the first "Download" rounded square button below "Java SE Downloads"

3.	Accept the license agreement and click on the appropriate filename to download the JDK installer. For example, for Windows 64-bit click on "jdk-8-windows-x64.exe".

4.	Run the JDK installer or self-extracting binary. JDK installation instructions can be found at "http://www.oracle.com/technetwork/java/javase/index-137561.html".

 

After installation, verify that the PATH variable includes the JDK bin directory.

On Windows platforms, the JDK and JRE are installed in subdirectories of "C:\Program Files\Java". For example:

C:\Program Files\Java\jdk1.8.0

On UNIX and Linux platforms, the JDK and JRE may be installed in any directory. It is common to see "/opt/java" on Linux. For example:

/opt/java/jdk1.8.0

Note - Oracle doesn’t provide Java for every UNIX platform. Some UNIX platforms provide their own Java environment. Refer to your UNIX documentation for details.
