I have an applet that I have signed using keytool and jarsigner. I am able to run the applet and write to the local file system. But I changed my code to test connecting to a MySQL database, jared the class file, resigned the jar file and now I get an AccessControlException. I know the database is working and I know my connectino code and my archive properties in my html file are correct. I can run the same code as an application and everything works fine. So I am assuming it is a security problem. Anyone able to shed some light on this?
