Installation instructionsUnpack the distribution. It will create a new folder/directory called “EJS_X.X” (where X.X stands for the current version, such as “EJS_4.2”), and that folder/directory will contain: the file “EjsConsole.jar”, and three folders/directories: “bin”, “doc”, and “workspace”.
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.)
