OutsideViewWEB and Java Virtual Machines

Technical Note

OutsideViewWEB requires a web browser with a Java Virtual Machine (VM) that fully supports version 1.1 of the Java Development Kit (JDK 1.1). You may experience problems running OutsideViewWEB on certain VM versions. Use this technical note to identify your VM version and obtain a VM that works well with OutsideViewWEB.

Java Virtual Machine

The Java Virtual Machine (VM) is the engine that processes Java programs and applets. Java instructions are not executed directly by the hardware of the local computer. Instead, the VM intercepts and compiles the Java code so that it can run in the browser's environment. This allows Java developers to write one standard Java program that can be run on multiple platforms.

Problems with Java Virtual Machines

Even if your browser is supported by OutsideViewWEB, it may be running with a VM that cannot run OutsideViewWEB with full functionality. Many products, such as Visual Studio, install their own versions of the VM, overwriting the VM originally included with the browser.

If you experience one of the following errors when running OutsideViewWEB, proceed to the sections below to determine if the problem is caused by your VM version:

	Applets appear as red or gray boxes on the Administrative WebStation pages.
	OutsideViewWEB sessions crash when loading a configuration file.
	An error appears when exiting Internet Explorer after running OutsideViewWEB.
	In the Button Palette Setup or Keyboard Map Setup dialog boxes, switching from the terminal keyboard view to the transmit string view causes a Java exception in Internet Explorer.
	In Netscape browsers, OutsideViewWEB cannot switch to another emulation type within the same browser session.
	In Internet Explorer 5.0, the Administrative WebStation Search tool always returns the following result: Number of pages found:0
	When metering is enabled and a metering host is required, a host connection cannot be made because the metering host does not respond.
	In Internet Explorer, if you browse to another web page while running a OutsideViewWEB session with an encrypted connection in a separate window, you will not be able to reconnect to the host. The following error message appears: Could not find certificate in storage
	When printing, the margin widths on printouts do not match the margins specified in the Print Setup dialog box.

Internet Explorer for Windows

If you experience problems running OutsideViewWEB with Internet Explorer for Windows, follow the steps below to identify the version of your Java VM, and then compare it with the list titled Problematic VMs. (These VMs may not run OutsideViewWEB with full functionality.)

Determining Your Java Virtual Machine Version

To determine the version of your VM, follow these steps:

Open the MS-DOS Command Prompt. At the command line, enter:
jview (for Microsoft VM)
java -version (for Sun Java)

Look for the version number on the first line returned.

Compare your VM version to the VMs listed below. If your VM appears on the list, proceed to the next section to obtain the most recent VM.

Obtaining the Latest Java VM

You may obtain the Sun Java Plug-in by going to http://java.sun.com/j2se/ and downloading their latest J2SE.

The Microsoft VM is no longer available through Microsoft's Install on Demand feature or as a download. The latest version of Microsoft Internet Explorer no longer includes a VM by default. You may obtain an archived copy of the Microsoft VM from this web site by going to our Support, Downloads page.

Known Issue

The Sun Java Plug-in and the Microsoft Java VM are not compatible. Therefore, when creating sessions within Deployment Director, it is necessary to identify which VM is expected. In environments where users may be running either VM, it is necessary to create two versions of each session file - one for Microsoft vm and one for Sun Java.
