Client platforms known to be compatible
with Reciprocal Net site software
Most users interact with Reciprocal Net site software by way of a web browser. The site software includes several Java applets for molecular visualization, some of which require special client-side support in order to function. Among these visualization tools are miniJaMM, JaMM1, and JaMM2 (the most advanced applet). This document details client-side environments that have been reported to be compatible.

Sun’s Java plug-in, also called the Java Runtime Environment, is a free download available from http://java.sun.com/. Netscape 4.x is compatible only with older versions of the plug-in earlier than 1.3. Netscape 6.x and 7.x are compatible only with newer versions of the plug-in (version 1.3 and later). Netscape 6 and 7 frequently are bundled with Sun’s Java plug-in, however, and thus in many cases a separate download is not required.
Microsoft’s Java VM, included with many versions of Internet Explorer and available as an optional add-on for others, does not support the newest Java standards and therefore is not compatible with JaMM2. The solution is to install and use Sun’s Java VM instead.
Sun’s Java plug-in, also called the Java Runtime Environment, is a free download available from http://java.sun.com/. For version 1.4.1-01, the runtime environment installs itself (including the plug-in) to the /usr/java/j2re-1.4.1_01/ directory. To activate the plug-in under Mozilla, create a symlink in /usr/lib/Mozilla-1.0.1/plugins/ (or similar) to the file /usr/java/j2re-1.4.1_01/plugin/i386/ns610/libjavaplugin_oji.so. Yes, the Java plug-in that Sun intended for use with Netscape 6.1 also happens to be compatible with Mozilla 1.0.1.
Macintosh Runtime for Java (MRJ) is an add-on to OS 9 published by Apple. Only the newest version (2.2.5) has been tested, but earlier versions might also be compatible. MRJ is a free download from http://www.apple.com/java/.
Microsoft Internet Explorer detects the presence of MRJ and seamlessly activates the MRJ plug-in when necessary; no special configuration is required.
Netscape Navigator includes its own Java VM that is not compatible with any of the visualization applets. The solution is to install a plug-in that couples Netscape to MRJ and allows Netscape to utilize MRJ’s Java VM instead of its own. The MRJ plug-in for Netscape was created by the Mozilla project and is a free download from http://www.mozilla.org/oji/MRJPlugin.html. Once the package is installed, the plug-in must be copied to Netscape’s Plugins directory and Netscape must be instructed to utilize the plug-in (inside Netscape, go to Edit/Preferences/Advanced and click the appropriate check box).
Unfortunately there is no Java VM available for MacOS 9 that would support the advanced Java features that JaMM2 requires. Purportedly MacOS X has such support, but this has not been verified.
