Successfully launching Web Meet Live depends on having a properly configured Java installation. This means that Java, Java Web Start and your web browser successfully work together to launch an application.

Note: Much of this article applies only to users of Microsoft Windows. Java comes pre-installed on the Mac and is therefore unlikely to be mis-configured.

The following test will determine if you are able to launch a sample Java program using Java Web Start. At this point, we are testing only your Java installation — This test does not involve Web Meet Live in any way. Unfortunately, Apple still ships Java version 5, and the sample application below requires Java version 6.

Click the following link: Progress Bar Demo

If Java is working properly, you should see a “Java Starting” window followed by the “Progress Bar Demo” sample application.

If you see the windows above, then your Java installation is properly configured.

If you do not see the windows above, follow the steps below to update your Java installation. This will ensure that you are running the latest Java update and that no older versions of Java are getting in the way. It will also update your web browser settings to work properly with the new installation.

1. Print out this guide as a reference
2. Restart your computer. This step is important to ensure that none of the Java files are in use.
3. Close any applications that run automatically at startup.
4. Open Windows Control Panel -> Add/Remove Programs (Programs and Features on Vista).
5. Uninstall any program from Sun Microsystems beginning with Java or J2SE. Four such applications are pictured below, and all should be removed.
   
6. Restart your computer. This step will allow windows to clean up any remaining Java files.
7. Close any applications that run automatically at startup.
8. Open your web browser
9. Install the latest Java from:
   http://www.java.com/en/download/manual.jsp
10. Attempt to launch the Progress Bar Demo application

If the sample application still does not launch, then verify that you are running the latest version of your web browser. Windows users should be running the latest version of Internet Explorer or Firefox. Mac users should be running the latest update of Safari or Firefox.

If your browser is fully up to date, and you still cannot launch the sample application, then then trying a different browser will help determine if the problem is with your Java installation, or with your web browser configuration:

• Internet Explorer users: try the latest version of Firefox instead.
• Firefox users: try the latest version of Internet Explorer instead.

Following installation of a new browser, run the Java installation program again to be sure that Java has fully configured your new browser.

If changing browsers allows you to launch the sample application, then the problem is likely with your browser’s handling of JNLP files. Such problems can be caused by security software, spyware, download accelerators or other browser add-ons. Removing browser add-ons and/or reinstalling Java may resolve the issue, however, Web Meet Live cannot provide any specific advice on configuring 3rd party software.

If changing browsers, reinstalling Java and restarting your computer still do not enable running of the sample application, then some other issue on your computer is preventing Java and/or Java Web Start from functioning properly. Contact your security software vendor or PC manufacturer’s technical support department for assistance with the issue.
