Software Deployment

Setting the value of deployment.user.security.exception.sites property to a file for which users do not have write permission seems to be how it is done according to the documentation here

Probably the best place for this setting would be in a system level properties file, that way it is applied to all users, So to do this you need to create two files, firstly a

deployment.config file which should reside in the folder C:\windows\sun\java\deployment   

and contain the following lines

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

Then create  the second file named deployment.properties file also in  the folder C:\windows\sun\java\deployment

and add the following line to it

deployment.user.security.exception.sites=C\:/WINDOWS/Sun/Java/Deployment/exception.sites
