Java & Java3D Runtime Installation

To run the applets found in the Free Software section of this website, you will need to install the Java Standard Edition runtime environment, which can be downloaded from http://java.sun.com. For those applets that use 3D graphics, you will also need to install the Java3D Optional Package, which can be found at http://java.sun.com/products/java-media/3D/. Please read the installation instructions included on the Sun website as they offer help with most problems likely to be encountered.

Running An Applet

The Exploratories applet description pages include links in the left-hand margin that launch the specified applet in a number of ways:
  • Run with JavaWebStart will attempt to run the applet using the JavaWebStart engine included with modern releases of the Java Runtime Environment. The applet will run in a separate window and a copy will be cached locally, allowing you to access the applet whether or not your computer is online.
  • Run with browser java will attempt to run the applet using the Java virtual machine that came packaged with the browser you have installed on your computer. This may not work for certain applets on this website, as they use extensions and features that are not typically included in the browser Java virtual machines. You will need to be connected to the internet to use this method.
  • Run with java plugin will attempt to run the applet using the Sun Java plugin which gets installed when you install the Sun Java Runtime Environment. The applet will be embedded inside a web page and your computer must be connected to the internet.
  • Download JAR file allows you to download the applet to your local hard drive. If you have the Java Runtime Environment installed, this will allow you to double click your local copy of the JAR file to run the applet. You will not need to be online to do so.
