In order to run JavaRisk you will need the Java Runtime Environment (JRE) at a minimum,
if you wish to edit and compile the source code you will need the Java SDK.
Download the JRE or the SDK here.  Note: This will open in a new window.

In either case version 1.4 or higher will be needed to run JavaRisk.
Please follow the directions given on the Sun site for installation regarding your platform.

Be sure to set up the bin path for the Java runtime:
If you don't do this or if the installation does not do it for you, you will have to
give the full path to the Java runtime when executing it.
i.e.
Linux: /usr/java/bin/java -jar JRiskv2_0.84.jar
Windows: c:\Program Files\Java\Java.exe -jar JRiskv2_0.84.jar

For Linux just append the path to the Java bin directory to your PATH environment variable.
i.e.

PATH=$PATH:/usr/java/bin
export PATH
You can include this in your startup scripts either for the machine or for the user.


This is only neccesary if the installer did not do this for you.
For Windows, you will need to add the path to the system or user variable PATH.
  1. To do this open the Control Panel and select System.
  2. Select Advanced and click the Environment Variables button.
    You should see a screen like this:
    • The top list shows the environment variables for the currently logged on user.
      Setting the PATH here will only apply to that user.
    • The bottom list shows the environment variables for the system.
      Setting the PATH here will apply to all users.
  3. We will go ahead and set it system wide, as that is probably what you want to do anyway.
    • In the bottom list scroll until you see PATH in the Variable column and select it.
    • Click the edit button.
      You will see a screen like this:
    • Go to the end of the path and add the path to the Java runtime.
      c:\Program Files\Java\bin

      Dont't forget to put a semicolon (;) after the last path before you add the path for the Java runtime.
