Applet did not start or is not privileged


EnlightKS Candidate requires a Java web browser plug-in to be installed and functioning. If your browser cannot start a Java applet, or if Java runs with insufficient permissions you will not be able to start a test.

Problem reported by the System Requirements Check:

  1. If there is a message "Java: Not starting" or "Applet startup", then the browser is unable to start Java at all. View details.
  2. If there is a message "Privileged No", then Java is functioning but has insufficient permissions. View details.
  3. If there is a message "Java enabled in browser: False", then java is disabled in the browser settings. View details.

Verify that the browser can run Java applets

If Java is installed, you can run Sun's Java test applet to verify that that you can run applets in your browser.

  1. Download and run both applets. If one of them runs but not the other, then there is a problem with your configuration.
  2. Check if you can open the Java Console. Read this if you want to know how to enable the Java Console.

If Java is installed but the download fails you will be able to see this in the Java console. If you need help with this problem, please include the contents of the Java console when contacting EnlightKS support.

In some cases a proxy or content filtering firewall may block applets (.jar files) from being downloaded and you may need to contact your network administrator.

Permission problems

EnlightKS Candidate requires that you can run a privileged Java applet. The first time you start a test, the Java Security Warning dialog will be shown. The Java Security Warning also shows up when the digital signature of the applet has not been accepted. The warning should provide a guarantee that the digital signature has been validated by a trusted source and that the applet is secure.

A checkbox, labeled "Always trust content from this publisher" or similar enables you to approve that you trust this content. If you mark the checkbox and answer "Run" tot the dialog, the warning will not appear again and the certificate will be permanently approved.

In some cases, an administrator may have disabled these warnings to that a regular user cannot approve applets to run. In such case an action may be required by your administrator.

If you answer "Cancel" on the Java Security Warning, the security certificate will not be approved for the current session and you will be unable to use any tests until you restart your browser.

If the Java Security Warning does not show at all even after restarting your web browser, try the following:

  1. Open the Control Panel.
  2. Open Java.
  3. Click on the Security tab.
  4. Click on trusted certificates and list trusted certificates in the User tab.
  5. Select the certificate identified by Enlight AB or EnlightKS AB. Press delete.

Enable Java in browser

In Firefox, Java can be enabled/disabled in the Tools->Options menu. There is a checkbox for Enable Java and that must be checked.

Other problems with the Java installation

Your java installation may be too old, unsupported or broken. Typically it is easier to just reinstall it than to pinpoint the problem. We suggest that you download the latest version and install it. For details, see Installing Java.

We have also seen problems at customers with a large number of versions installed in parallel and with multiple 1.4, 1.5, and 1.6 versions in parallel. The solution for them was to uninstall all their java versions and re-install only the latest one.

Installing Java

Please note that to install Java on your computer, you will need to have administrative permissions on it. In many classroom situations this is typically not the case and an administrator will have to perform the required steps for you.
