Java system level deployment.properties

Question

Since 7u10, Java show new "out of date" warning if not using newest jre version. Java updates have been cause problems for our Java Web Start application. We want test our application with new update before we can say to our customers that its ok to update Java. I have trying to block new "out of date" warning in system level with no results. I have created two files deployment.config and deployment.properties in path C:\WINDOWS\Sun\Java\Deployment\ but looks like nothing works.

deployment.config-file:

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

deployment.properties-file:

deployment.javaws.autodownload=NEVER
deployment.expiration.check.enabled=false

Answer 1

deployment.system.config is the URL to the system (enterprise-wide) deployment.properties file. This property can be used by system administrators to centrally administer or "lock-down" user-specific configuration settings. For local files, use the file protocol in the URL, for example, file:///C:/Windows/Sun/Java/Deployment/deployment.properties.

Note the forward slashes (I had this issue before).

Answer 2

Your folder path is wrong - C\:/WINDOWS/Sun/Java/Deployment/deployment.properties

Try C:\Windows\Sun\Java\Deployment\deployment.properties

Answer 3

This deployment.expiration.check.enabled=false property works only starting from Java 7 Update 40 Which version are you testing ?
