Chalk - Clear Java Cache (Instructor and Student)

This article explains how instructors and students can clear their Java Plug-in Cache in both Windows and Mac computers, should they receive a Certificate pop-up when using various tool options and the control panel in Chalk.

To Clear Java Plug-In Cache (Windows-All Versions)

Occasionally, after logging into Chalk and trying to use a course tool (students and instructors) or the control panel (instructors), a pop-up certificate warning may appear. If this happens, just answer "yes" or "accept". But if a problem occurs thereafter, clearing the Java Cache helps. Here are the directions to clear the Java cache.

  1. Click Start > Control Panel.
  2. Double-click the Java icon in the control panel.
    The Java Control Panel appears.

  3. Click Settings under Temporary Internet Files.
    The Temporary Files Settings dialog box appears.

  4. Click Delete Files.
    The Delete Temporary Files dialog box appears.

  5. Click OK on Delete Temporary Files window.
    Note: This deletes all the Downloaded Applications and Applets from the cache.
  6. Click OK on Temporary Files Settings window.
    Note: If you want to delete a specific application and applet from the cache, click on View Application and View Applet options respectively.
