[Lilux-help] S-NET and openjdk

Hi everyone, I've tried to use openjdk 6 and the corresponding icedtea Firefox plugin as a replacement for sun-java-6 on Ubuntu 11.10 for accessing BCEE's S-NET site. I get the infamous message: "exception: java.security.AccessControlException : access denied" and the applet does not start. In the same situation, during the first access to the site, the old sun java plugin ran a popup asking whether the user would grant permission to execute the applet and updated its config accordingly. This is apparently missing in icedtea's (or openjdk's?) setup. Of course, I can make it work by writing a ~/.java.policy with grant { permission java.security.AllPermission; }; but the security implications are severe, to say the least. Any advice? Thanks Alain
