Applet Firmado: Acceso Denegado

[dominguez]

Hola,

Tengo un applet firmado que accede a disco. Cuando ese acceso se hace desde los métodos init() o start() no hay ningún problema. Pero si el acceso se hace desde otro método al que se llama desde JavaScript, entonces se deniega el acceso y da el siguiente error:

java.security.AccessControlException: access denied (java.io.FilePermission C:\ejemplo.txt write)
at java.security.AccessControlContext.checkPermission (Unknown Source)

¿Es posible llamar al método concreto desde Javascript o hay que tener el código en los métodos que se llaman automáticamente?


Saludos.
