Class LicenseLoader

java.lang.Object
  com.antelmann.util.LicenseLoader

All Implemented Interfaces:

LicenseHandler

public class LicenseLoader
extends Object
implements LicenseHandler

can be used to acquire licenses from a known location on demand. The LicenseLoader can be initialized to first check a list of URLs to be loaded to acquire the needed license. Only if that fails (or if no URLs were configured to begin with), an upcoming dialog will enable the user to provide a location from where a final attempt is made to load the required license. If that last resort fails, too, a LicensingException to be thrown may be inevidable.
