Java security settings

January 28, 2014

Java 7u51 has been a headache so far with security settings, especially on a terminalserver. I needed to adjust the security setting for Java for all users on the terminalserver and add a website (example.com) to the exception site list in Java.

The solution was to create 3 text files and place them all in the folder C:\Windows\Sun\Java\Deployment

filename: Deployment.config

deployment.system.config=C:\WINDOWS\Sun\Java\Deployment\deployment.properties
deployment.system.config.mandatory=true

filename: deployment.properties

deployment.security.level=MEDIUM
deployment.security.level.locked=
deployment.user.security.exception.sites=C\:\\WINDOWS\\Sun\\Java\\Deployment\\exception.sites

filename: exception.sites

https://www.example.com

After these 3 textfiles are created, the new java settings till take effect at next logon, and you can verify it by looking at the security tab in java control panel.
