Read/Write files

Hi real-genius.

My question (problem): we need run read/write operations over local files from an applet. Our requirements:

  1.- The applet must run in NetS & IE
  2.- File we must read/write contains ascii code, and it`s in the same machine where applet runs.

We know the possibility to sign applets, but we prefer study other ways (if it`s possible).

Thank`s at all.

yes it is possible,
instead of signing the applet you edit a policy file that grant rights (read/write on the client machine) to your applet specifying the name of the applet and the URL to it.

you can use the policytool to create policy files

more exactly go trough
http://java.sun.com/docs/books/tutorial/security1.2/tour1/index.html

and stay focused on "A CodeBase value indicates the code source location; you grant the permission(s) to code from that location. An empty CodeBase entry signifies "any code" -- it doesn't matter where the code originates"
