JEOPS - The Java Embedded Object Production System

Download Page

Version: beta 1 - July 2, 1999
Author: Carlos Figueira Filho

Installation instructions

JEOPS source code is packaged as a single ZIP file. To use it, download the file (link below), extract the files inside it to a directory that is in your classpath, and then compile them. For example, if you download it to the c:\jdk\classes directory, including the following line into the autoexec.bat will set the system to work with JEOPS (if that directory was not already in the classpath):

set CLASSPATH=%CLASSPATH%;c:\jdk\classes

Under unix systems, if the file was downloaded into the /usr/local/bin/classes directory, the following command will set the classpath environment variable so that JEOPS can be used:

setenv CLASSPATH=$CLASSPATH:/usr/local/bin/classes

Actually, the syntax of the above command can be slightly different, depending on the unix shell you're using.

Note: JEOPS is not distributed in its compiled form due to a bug found when I compiled it with JDK 1.1 and tried to use it with JDK 1.2 (a NoSuchMethodException was thrown). In order to avoid this problem, I removed the compiled package from this download page.

Downloading JEOPS (Source Code)

Click to download (76KB) (see note above!)

If it doesn't work, try clicking the link with the right button of the mouse, and then choosing the "Save link as..." option in the popup menu to save it.

You're free to get JEOPS source code and modify it in order to suit your needs, as long as you agree to:
  1. Notify me of any changes made in the software;
  2. Preserve my name as one of the creators of the software.
Inside the zip file, there are also two rule files, used with the examples of the system, hanoi.rules and fibo.rules.
