[java] accessing files from web-page applets

It may be possible if you sign your jar file containing any classes that directly or indirectly access the file you want to save to. I used this method to access a database to save high scores for a game I did, but I''ve never used to access a normal file. I ran across a thread on sun''s java forums once that described how to do it step by step. Unfortunately I lost the URL to it. I''m sure you could find it if you looked though.

Doing IO directly from your applet to your server is a bad idea, because that will open you up to all sorts of exploits. Best solutions would be to invoke a script on the server or perhaps have your own daemon running which accepts a TCP connection on a specific port of your server which processes high scores. Neither of these will require your jar to be signed.

Try using Servlet, since your already in the stuck with Sun you might as well give it a shot(instead of php that is)

Here is how to sign an applet:

I never manage to make it work,
maybe you will have better luck!

Yeah, you need to call a CGI on your server as if it were a webpage. The Java implementation is easy, what''s going to get you is the CGI programming (if you''ve never done it before). However, you don''t HAVE to use PHP . . . Perl would work just as well (and is my personal favorite) . . . if you got into any serious CGI programming, PHP would be laughed upon (for example, cgi-resources.com has 3x as many Perl scripts).
