ARCHIVE - Java Settings - Manually configure Java to allow Voyant to be cached, allow desktop shortcuts, and to work through proxy servers **Voyant Adviser, UK and Ireland**

How to manually configure the Java Runtime Environment (only when necessary)

If left to its default settings, Java (the JRE) should normally be set to allow Voyant to be installed, cached and launched and for shortcuts to be created on the computer for use in launching the software in the future. Moreover, updates of the software should be delivered to the computer automatically via Java WebStart. There are, however, a few settings to check in case you encounter problems launching the software.

To check Java settings, launch the Java Control Panel. On Windows computers the control panel can be launched either by going to the Start menu, select Control Panel, select Programs, and click Java. On older version of Windows you may need to go down a level into Programs and select Java.

On Mac OS, click Macintosh HD (the Apple icon top-left) > Applications > Utilities > Java > Java Plugin Settings.

The Java control panel should open, as shown right. Click the Settings button, bottom-right.



Allow Files to be Cached Locally into Java

Voyant is cached into Java WebStart; therefore, Java must be configured (as it should be by default) to allow files to be stored locally.

Verify that the “Keep temporary files on my computer” option is ticked.

If unticked, files for Voyant cannot be cached locally and the software will not run.

On the same panel, disk space should be configured to allow for adequate space to cache application files. Ideally, set this to the maximum allowable caching space.



Allow Java to Create Desktop Links

Voyant is normally launched via links added to the computer desktop and on Windows computers, in the Windows Start menu, All Programs menu > Voyant Adviser folder.


To allow these links to be added to the computer during installation, Java should be left, by default, to allow desktop links, as shown in the settings below. You might change this setting to Always Allow, but this should not be required. 


How to manually configure proxy server settings in Java

If you are unable to launch the application, it may be that your network uses a proxy server and the special settings required to pass requests through the proxy server are not being passed successfully from the browser to Java.

Normally, Java should detect these settings automatically from the default browser. However, if you are experiencing problems launching and your network uses a proxy server or an automatic proxy configuration script, you may add these settings manually, if necessary, on the Java Control Panel.

Tip: If you are having problems launching Voyant but aren't sure whether your requests are being routed through a local or network proxy server, a good place to check is in your browser's settings on the computer in question. Read more >>
