Choosing a JVM for an Express Terminal Configuration

The Express Terminals included with Terminal Viewers are Java applets that require a virtual machine (also known as a runtime environment) in order to operate.

As indicated in the Readme file, certain versions of Microsoft virtual machine (VM) are required, and one of these versions must be installed at the clients before the clients can use the viewers and printer applets.

If the clients have problems running the viewers or printer applets using Microsoft VM, you can modify the configurations to use Sun Java 2 Runtime Environment (JRE) instead. However, if the clients use Sun JRE, and the viewer or printer applet appears in a secondary window, going to a different Web page closes the viewer or printer applet. To have multiple viewer or printer applet windows open simultaneously, you must either use Presentation Integrator to launch multiple viewers or printer applets from a single presentation, or users must open a separate instance of the browser each time they want to access a different viewer or printer applet. (To open a separate instance of the browser directly from the Presentations page, users can right-click the presentation and then click Open In New Window.)

Microsoft Virtual Machine

To obtain the latest version of Microsoft VM, users can go to, click Downloads, and follow the instructions. If they save the file rather than opening it, they must run the saved file before they can use the viewers or printer applets. In addition, when they have finished installing Microsoft VM, they must reboot their computers.

Alternatively, if you do not want users to access the Internet for this file, you can save it on a corporate server and have users install it from that location.

Sun Java 2 Runtime Environment

If you select Use Sun VM in a configuration's Display Properties, and Sun JRE 1.3.1 is not installed on the client, the user is prompted to install it.

For clients that run Internet Explorer (IE) 5.5 or newer, the installation of Sun JRE begins automatically as soon as the user accesses the presentation, and the viewer or printer applet runs as soon as the installation of Sun JRE is complete.

Clients that run earlier versions of IE or Netscape Communicator are prompted to initiate the installation, and the users must manually return to the Presentations page when the installation is complete.

To obtain the latest version of Sun JRE, users can go to, click Download, and follow the instructions.
