Users with additional or updated information to share regarding Java plug-ins and JSim compatibility with different browsers should contact us.

Windows Plugin Configuration

Configuration for Windows 7 and Windows 10:

Mac OS X Configuration

Java 1.5 is pre-installed on Mac OS 10.4 "Tiger", OS 10.5 "Leopard" and OS 10.6 "Snow Leopard". JSim will not currently run on Mac OS 10.3 or lower due to the lack of Java 1.5 support

Mac OS 10.7 "Lion" does not have the Java plugin installed. Java must be installed and the plugin enabled in your browser.
To install browser support for java applets:

Java 6 plugins

As of July 23, 2007 the JSim applet requires the user's browser have a Sun Java 6 compatible plug-in installed. Previously, Java 1.4 and 1.5 plug-ins were supported. Those still using 1.4 or 1.5 plug-ins should update their Java plugins. Older versions of Sun's Java plug-in or off-market Java plug-ins may not run JSim correctly.

NSR Systems

The Java 1.6 SDK has already been downloaded on NSR systems in /usr/local/jdk1.6. To install the Java 1.6 plugin under Firefox Linux on NSR systems, you need only issue the following commands:
