How to make a applet write to locl file,when it runs in broswer?

[walter wang]

I know usually applet run is sandbox,it couldnot
write to local file.
but if i change policy file eg
grant{
permission java.security.AllPermission ;
};
then in Dos box ,enter command line
appletviewer -J-Djava.security.policy=pathtopolicy myApplet
then myApplet could write to local file,
but how could myApplet write to local file when
it runs in browser?
thanks in advance.
