032/**
033 * This is just an empty implementation of DownloadService.  It does define
034 * only the methods of the JNLP API used in the class 
035 * org.opends.quicksetup.webstart.WebstartDownloader.
036 * 
037 * We have chosen to do this because we we require the JNLP API to be compiled
038 * but the location of the javaws.jar depends on the java distribution, so
039 * instead of trying to figure out where javaws.jar is on the java distribution
040 * that is being used to compile the source, we just add these classes to the
041 * build-tools.jar file that will be used to compile que QuickSetup.
042 * 
043 * It must be noted that the class 
044 * org.opends.quicksetup.webstart.WebstartDownloader will be only executed in
045 * the context of a Java Web Start application and that in this case the
046 * javaws.jar will be provided by the Java Web Start Runtime environment.  So
047 * we are not providing the javaws-stub.jar during runtime: it is used only
048 * for compilation.
