I have the following JNLP; and in DownloadTracker, I am implementing DownloadServiceListner, but the progress methods and other methods, dont' get called even once. In the JWS logs, I can see progress entries, but why doesn't javaws.jar never call my methods ?
After seeing your post, I tried several existing CustomProgress test we have, and can not see any problems.
My best guess is that the Java Web Start code could not Initialize the preloader with your progress class.
1.) Can you show the constructors in the class downloadtracker.DownloadTracker in downloadtracker.jar ?
2.) Can you show the trace messages when run with deployment.trace.level="preloader" or "all" ?
