I will bother later about security and performance (I heard that SSL can encrypt my password). I am not sure what I want to do so I might make a simple game applet that saves the score . And this shouldn't be such a bad idea... What about World of Warcraft or Guild Wars . Don't they use a database to store the positions , the levels etc. ?Anyway ...I'll use this or I don't , I would still like to know why this is not working.
About the java database , I don't have enough time to learn that now (School

) .
