Occasionally a problem arises involving the Java cache. Most typically this is seen in cases where the Blackboard gradebook fails to load, but instead a blank white screen appears. The solution to this problem is to clear the browser cache and then the Java cache. To clear the Java cache, complete following steps:

Windows

  1. Open a web browser and login to Blackboard. This will initiate Java on your computer.
  2. Look for the Java icon located in the bottom-right corner of the Windows task bar.
  3. Right click on the icon and select "Open Control Panel."
  4. Once the control panel is open, click the "Settings" button under the General tab.
  5. Next, click the "Delete Files" button.
  6. When prompted to "Delete the following temporary files," make sure both options are checked and click "OK."

Mac OSX

  1. Using the spotlight tool, search for "Java Preferences"
  2. Open Java Preferences and click the "Network" tab.
  3. Click the "Delete Files" button.
  4. When prompted to "Delete the following temporary files," make sure both options are checked and click "OK."
