Technology is great but real things are better, so on UP2GO.NET you will get nearly a hundred applications. This site also offers ratings, spot light, 10 best, user ratings and comments. The site is still under construction but ideas seem to be welcomed.
[Editor's note: I admit I had hardly touched Java Web Start until I got this hint. Many of the apps on the site will not run (I tried quite a few), but a good number do run when clicked in Mozilla. When the download window pops up, just make sure "Open with Java Web Start" is selected and everything should be automatic. One of the more impressive things to see running was JavaZOOM, a clone of the WinAmp MP3 player. It loaded and played my MP3s, although its CPU utilization is notably higher than that of iTunes ;-).
One note of caution - when you launch some of these programs, you are giving them full permission to access your machine. They could do malicious things to your system without your knowledge. I stuck to apps that had an editor's review, and made sure I had a good backup prior to experimenting. With that warning stated, I don't expect that anything on the site is malicious.
There may be other sites with collections of Java Web Start apps on them, but I haven't seen any other than this one.]
