Two questions.
Firstly, are multiple entries permitted? I have my first idea at working-prototype stage in 24 hours, so I may have time to get my second idea developed inside three weeks too.
Secondly, what should the codebase and documentbase of the JNLP file be?
You can submit as many games as you like.
If you host your game files (JNLP and JAR) then you will decide on how’s it is set up. This is how most do it. All you do when you submit your game is to provide an URL to the JNLP file on your webserver.
If you cannot host your game files anywhere, you can submit your game on the Java4k.com submission page. Simply define a dummy JNLP url, then you send me an email with the JAR and somewhat correct JNLP (I’ll make it work). My email is on the submission page.
Oh, I assumed you wanted to host it to guarantee availability in the future.
If multiple games are allowed then there’s no reason for me to hold back on posting the first one I’m working on.
