code: private String getProperty(String property) {
          return has(System.getProperty(property)) ? System.getProperty(property)
                  : has(userConfigFile.getProperty(property)) ? userConfigFile.getProperty(property)
                  : adminConfigFile.getProperty(property);
      }
docs: First tries to load the property from java system properties
  secondly looks for the property into user defined admin-config.properties then if
  not found load defaults from admin-config.properties provided within admin-template
  
  @param property name
  @return
