A configuration file must be present to deploy properties for JRE.
The deployment.config file is used for specifying the location and execution of system-level properties for the Java Runtime Environment. By default no deployment.config file exists; thus, no system-wide deployment.properties file exists. Without the deployment.config file, setting particular options for the Java control panel is impossible.
NOTE: The 'JRE' directory in the file path may reflect the specific JRE release installed.
