MRJ IS NOT INSTALLED OR NOT ENABLED
The MRJ is the software that allows Java applications and applets to run under the Macintosh Operating System. In order to run the Periodic Table Live! Graphing Applet on your computer, the MRJ files MUST be installed on your system. Additionally, the web-browser that you are using must have java and the MRJ enabled.
In order for this particular applet to run, MRJ version 2.2 or higher is required. The fact that you are viewing this page indicates that either the MRJ software does not exist on your computer, or that MRJ is not enabled in your web-browser. In order to correct this problem, follow the instructions below.
IF YOU THINK THAT THE MRJ SOFTWARE DOES EXIST ON YOUR SYSTEM:
If the MRJ is present on your system, your must enable it in your web browser.
Netscape Navigator:
Even if MRJ is present on you system, Netscape Navigator (all versions) requires a plug-in to be installed before it can use the MRJ software. There are separate plug-ins for Netscape version 4 and version 6. Both of these plug-ins can be found on this CD in the Installation:Macintosh:MRJPlugin folder. Click here for more complete directions. Alternatively, this plug-in can be downloaded free of charge from Mozzilla at http://www.mozilla.com/oji/MRJPlugin.html. From this page, download the plug-in folder and follow the installation instructions. Once the plug-in has been installed to your Netscape Navigator directory, from the Netscape Navigator menu bar select Edit -> Preferences -> Advanced. Select the check-boxes labeled Enable Java and Use MRJ.
Internet Explorer:
If MRJ is present on your system, Internet Explorer will use it to handle any Java applets by default. Therefore, you simply need to enable java. To enable Java, select the Edit menu from the Internet Explorer menu bar. Then select Preferences -> Web Browser -> Java, and select the checkbox labled Enable Java. Note that if MRJ exists on your system, the check-box will actually be labeled Enable Java (Apple MRJ). If the label does not contain the text Apple MRJ, then MRJ does not exist on your system, and you will need to install it.
IF THE MRJ SOFTWARE DOES NOT EXIST ON YOUR SYSTEM:
If the MRJ Software version 2.2 or higher does not exist on your system, you will need to install it. A number of steps will be required to install it.
The MRJ 2.2.4 software installer, which is the most recent version of the MRJ software that can be redistributed, is located on this CD in the Installation:Macintosh:MRJ Install folder. To run the installer, double-click the file named Installer, and follow the on-screen directions. The latest version of the MRJ software can be downloaded free of charge from http://developer.apple.com/java/download.html.
VERY IMPORTANT: The MRJ Software installed to your computer does not include one of the files required to run the Periodic Table Live! Graphing Applet. This file, which is named swingall.jar, is located on the CD in the Installation:Macintosh folder. After you have run the MRJ Installer, you must copy the swingall.jar file from the CD to your System. Swingall.jar needs to be placed on your computer in the folder System Folder:Extensions:MRJ Libraries:MRJClasses.
