Installation

Hardware and Software Requirements

Easy Java Simulations has been written completely in Java language and, as such, can be run on any hardware platform that supports Java 2. Ejs has been successfully tested on the following platforms:

Ejs itself requires (including examples) some 9 Mb of hard disk space. We always recommend as much memory as possible, but it should run well with 64 Mb.

Installing and Running Ejs

The distribution file is a Windows compressed ZIP file. Installation of Ejs consists in uncompressing this file anywhere on your hard disk.

To run Ejs, you'll need to have the Java Runtime Environment (JRE), versión 1.5 or later, installed in your computer. You can obtain the JRE from Sun's official server at http://java.sun.com.

To run Ejs, double-click on the EjsConsole.jar file that you will find in the directory created when you uncompressed Ejs. If this doesn't work, open a system terminal, change to Ejs directory, and type the command: "java -jar EjsConsole.jar". You may need to fully qualify the java command if it is not in your system path.
