But when one starts EJS, the 64 bit VM is used. In our installation, when one double clicks on a jar file, the 32 bit VM is used.

We use both the 32 bit and 64 bit Java VM and they work fine. We recommend that users only install the 32 bit VM unless they are very knowledgeable. Firefox, for example, needs the 32 bit VM to run applets because it is a 32 bit program. However, there can be complications because there are 32 and 64 bit Java Virtual machines (VM) for Windows.

For Linux/Unix environment details of how to obtain JRE vary from distribution to distribution, so no generic instructions can be given.

To this end, visit the Mac OS X update page for Java.

MacOS X comes with a fully configured and ready-to-use Java Development Kit.

For Windows, download the JRE installer it is available in both online (smaller initial download size) and offline (self-contained) versions.

(Note that only the Java Runtime Environment is needed the Java Development Kit contains JRE as well as other things which are not needed to run EJS.) The current version of EJS requires JRE 1.5 or later.

There is no problem in overwriting previous copies of the "bin", "doc", or other folders/directories under "workspace", and the "EjsConsole.jar" file. 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. 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.

The concept of an EJS workspace is discussed here. The folder/directory called "workspace" contains a sample work area.The "doc" directory contains a copy of this Wiki. Similarly, do not touch the folder/directory called "doc".The "bin" folder/directory contains the library files for EJS.

Do not alter any files within the folder/directory called "bin", and do not change the name of the folder/directory called "bin".

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".
