Java Plug-in Installation

The Java Plug-in is used to bypass the internal Java Virtual Machine (JVM) of your browser.

For example, Macintosh Netscape's internal JVM is very old and cannot run newer applets due to the rapidly changing nature of the Java language. By installing the MRJ Plug-in your Browser will use the external MRJ JVM which is very up-to-date.

Please choose your platform from the list provided below to install the plugin.
