Tracker Map View System Requirements

Below is an image of the Tracker Map View frame. If this frame does not appear when the applet is launched, check the System Requirements below.

Tracker Map View Display Map

System Requirements:

Windows:

Tracker Map View requires both a browser and a Java virtual machine. Tracker Map View works properly with either the Sun or Microsoft VM. However, Microsoft discontinued support for their VM, January 2004. For this reason, we recommend using the Sun Java Plug-in (currently version 1.4.2). [external link]

NOTE: There are issues with Tracker Map View not working properly with the Sun Java plug-in version 1.3. The symptom is that the applet will seem to start, the map will be displayed, but no data will be received. If this occurs, try upgrading the Java plug-in (to 1.4.x).

  • Netscape Communicator 4.5-4.8
    These older versions of Netscape [external link] have a built-in Java virtual machine. No separate plug-in is required.
  • Netscape 6/7
    These versions of Netscape require a Java plug-in, which is offered as an option when you download Netscape, or is otherwise available from Sun [external link].
    Download a current version of Netscape.
  • Mozilla
    Mozilla requires the Sun Java Plug-in [external link].
    Download a current versions of Mozilla [external link].
  • Microsoft Internet Explorer, versions 4.01 to 6
    Versions of IE prior to 6 included the Microsoft Virtual Machine, which does work with Busview. Version 6 does not include a Java virtual machine (though if you upgrade from an earlier version of IE, you will likely already have the Microsoft VM, which version 6 can use. If you install version 6 of IE and you do not already have the Microsoft VM, it is suggested that you download the Sun Java Plug-in [external link], which will also work with Internet Explorer 6.
    Download a current version of Internet Explorer.

Macintosh:

We do not have newer Macs available, and so we are not able to test Tracker Map View on current versions of the Mac OS. However, users have reported that Tracker Map View works fine under OSX 10.3.5, with Java 1.4.2, using Safari 1.2 or Mozilla 1.7. The following notes pertain to older Macs and browsers on which we have tested Tracker Map View.

Tracker Map View DOES work on the Mac with Internet Explorer 4.5 but only if you use the Apple 'Mac Runtime for Java' (MRJ) version 2.1 [external link] and NOT the Microsoft Java virtual machine that used to ship with IE. (MRJ2.1 requires a PowerPC with 32 MB of RAM and Mac OS 7.6.1 or later.)

Tracker Map View does NOT work with any current versions of Netscape Communicator/Navigator (through 4.6/4.08). Netscape does not support the necessary version of Java. A future release of Netscape is expected to include support for the Apple 'Mac Runtime for Java'. This should make it possible to run Busview under Netscape on the Mac.
