JAVA Information

CEM has experienced problems with newer versions JAVA SE Runtime software, due to increased security levels forced by JAVA.  (The higher security levels prevents some of the graphics from loading.) Version 7.0.9 (JAVA SE Runtime Environement 7u9) is the latest know version to run without causing any security issues within CEM, when using the standard JAVA installation settings.  Some users have indicated that changing the JAVA security level to “Medium” in the Java Control Panel can correct the issue, but it is unknown if this works for all JAVA versions that have this option available.  Starting with version 8u20, JAVA removed the “Medium” security level setting.

However, for versions 7u51 and later, the “Java Control Panel” was added, which contains the “Exception Site List” that will allow the applets to run on user designated websites or programs, and bypass the security level restrictions that cause problems within programs like CEM.

To configure the settings in Java using the “Exception Site List” to allow the applets to run in CEM, follow the step-by-step instructions contained in the PDF document below:

Note:  These procedures have only been validated on Windows 7, 8 & 10.  It is unknown if they work for earlier versions of Windows.
