We are searching with the search engines and even plan to launch our own spider just for that. However the search is difficult. There are some good applets that have been found after weeks of looking for. We wonder if anybody in the world would be able to find these when one needs to learn something for tomorrow.
We are working with SourceForge as well.
Please do not submit applet aggregating sites that cannot tell apart from Free software, free for non commercial use, free trial and free spam daily in your mailbox. Also, we currently cannot support the output of tools that generate executable java .jar or .class files only. We need the source code for reviewing, and the best to have it at least mostly human written.
We are interested in education applets. Game applets may only be interesting if they represent some really old, notable game. The playing strength of the applet does not matter, just needs to follow the rules. Applets that are just for decoration or general improvements of the web site (like upload applets) are the least interesting group.
Finally, we have hired the Duke as a campaign manager due lack of resources. We believe we understand correctly statements at http://java.sun.com/logos/ and then following the link under Duke to http://kenai.com/projects/duke/pages/Home that we have right for that.
