Running JSim inside a Web Browser

This page is for the older JSim version 1.6. Click here for the latest JSim 2.0 version.


JSim can run inside WWW pages as a Java applet. To do this, your browser must have an appropriate Java plugin installed. This page provides configuration information for many common platforms. For more information about JSim, see the JSim Home Page .

Java 5 & 6 plugins

As of July 23, 2007 the JSim applet requires the user's browser have a Sun Java 5 or 6 compatible plug-in installed. Previously, Java 1.4 plug-ins were supported. Those still using 1.4 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. At this time, we have tested Java 5, but not Java 6, plugins on this site. However, we have every expectation that Java 6 plugins should work fine.

Specific plugin configuration information:

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 2000 and XP:

Windows 98 is not officially supported, but here's some info anyway:

Mac OS X: no plugin is necessary

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:

Linux Plugin Configuration

The following tests apply to i386 Linux. amd64 and ia64 browsers have not yet been evaluated:

NSR Systems

The Java 1.5 SDK has already been downloaded on NSR systems in /usr/local/jdk1.5. To install the Java 1.5 plugin under Firefox Linux on NSR systems, you need only issue the following commands:

cd ~/.mozilla/plugins
ln -sf /usr/local/jdk1.5/jre/plugin/i386/ns7/
