Download and Install

Download

At minimum, you need to download the EJS bundle. If your system does not have Java installed, you will also have to download the installation package for the Java Runtime Environment.

 

  • Download the EJS package. The latest version is available at EJS release 4.0 (built on August 29th, 2008).

 

There have been important changes in version 4.0, including new features that will make your simulation experience even better. Previous users of EJS are advised to read the release notes. The package includes examples in a sample workspace directory. To obtain more examples, go to the Demos/Examples page.

 

Some users need the connection EJS with Matlab/Simulink (only available for Windows operating systems). This feature is not currently supported in version 4.0. If you really need this feature, then download EJS release 3.47 (built on March 1st, 2008). But only in you really need this feature! EJS 4.0 is far superior and is the only version currently supported.

 

  • The distribution file is a Windows compressed zip file, so you will need a tool to uncompress it. Most modern operating systems include one such tool. If not, here are our suggestions:
    • For Windows, use any of the zipping/unzipping tools. Such as 7-zip, available at http://www.7-zip.org, or the classical Winzip tool, available at http://www.winzip.com.
    • For Linux/Unix, there are several tools, such as unzip and gunzip. These usually come with the distribution.
    • For MacOS, use MacZip or StuffItExpander, available in several places.

 

Install

  • Unpack the distribution. It will create a new folder/directory called "EJS_X.X" (where X.X stands for the current version, such as "EJS_4.0"), and that folder/directory will contain: the file "EjsConsole.jar", and three folders/directories: "bin", "doc", and "workspace".
    • Do not alter any files within the folder/directory called "bin", and do not change the name of the folder/directory called "bin". The "bin" folder/directory contains the library files for EJS.
    • Similarly, do not touch the folder/directory called "doc". The "doc" directory contains a copy of this Wiki.
    • The folder/directory called "workspace" contains a sample work area. The concept of an EJS workspace is discussed here.

 

Note when reinstalling EJS: If you need to reinstall EJS, or upgrade to a newer version of it, follow the same procedure to unpack the new EJS bundle. You may want to make a backup copy of the existing "workspace/source" folder/directory in the installation directory (not your personal one) if you did changes to the sample simulation files included in it. There is no problem in overwriting or deleting the previous copies of the "bin", "doc", or other folders/directories under "workspace", and the "EjsConsole.jar" file.

 

  • If you need to install Java, go to http://java.sun.com/javase/downloads. The current version of EJS requires JRE 1.5 or later. (Note that only the Java Runtime Environment [JRE] is needed; the Java Development Kit [JDK] contains JRE as well as other things which are not needed to run EJS.)
    • For Windows, download the JRE installer; it is available in both online (smaller initial download size) and offline (self-contained) versions.
    • For Linux/Unix, download either the JRE installer or an rpm package which will do the installation.
    • MacOS X comes with a fully configured and ready-to-use Java Development Kit.
