Running JSim inside a Web Browser

Introduction

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:

• Windows
• Macintosh
• Linux
• NSR systems

Users with additional or updated information to share regarding Java plug-ins and JSim compatibility with different browsers should contact butterw@u.washington.edu.

Windows Plugin Configuration

Configuration for Windows 2000 and XP:

• Firefox 1.0.4: Runs fine with 1.5 plugin.
• Mozilla/Netscape: not yet tested.
• Internet Explorer: As part of its unending struggle to be incompatible with all common standards, Microsoft distributes a crippled version of Java that should not be used. JSim will run fine after installing one of the recommended Sun plugins. However, this browser is extraordinarily insecure, and a primary infection path for viruses, trojan horses and spy-ware. As a result, we strongly discourage use of IE.

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

• Netscape 7.2: works OK. Plug-in is pre-installed.
• Firefox 1.0: works OK. Plug-in is pre-installed.
• Internet Explorer: not yet tested.

Mac OS X: no plugin is necessary

Java 1.5 is pre-installed on "Mac OS 10.4 ""Tiger""":http://www.apple.com/macosx/tiger/. Earlier OS X versions (10.3 and lower) have only Java 1.4.2 installed; it is not possible to install Java 1.5 on these systems. JSim will not run with OS 10.2 or lower:

• Safari: recommended browser
• Firefox, Camino, Sea Monkey: The applet may be displayed only partially or remain blank. Scrolling or resizing the enclosing window will restore the applet. Some older versions may not work with 1.5 or not work at all.
• Netscape, Mozilla: PowerPC only. The current versions of this browsers cannot display JSim applets on Intel based Mac. For PowerPC-based macs, user must install Java plugin. See sourceforge.net . A more user-friendly set of installation instructions for this download may be found here . The binary files to be installed are in the ppc folder; those in the Binaries folder do not work. The applet may be displayed only partially or remain blank. Scrolling or resizing the enclosing window will restore the applet.
• Internet Explorer: does not work. The Macintosh version has officially been discontinued by Microsoft.

Linux Plugin Configuration

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

• FireFox/Mozilla works fine with the 1.5 version plug-in. User must install the plug-in first. Some older versions may not work with 1.5 plug-in.
• Netscape: not yet tested.

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/libjavaplugin_oji.so
