Hi,

Why would this does not work. I have tried it has an application and it
works fine.
I have an applet on my desktop (desktop=Bureau) and it does not works.

grant codeBase "file:${java.home}/Bureau" {
permission java.security.AllPermission;
permission java.util.PropertyPermission "os.name", "read";
};

child = new File(child.getParent());
}
return relPath;

You gave yourself permission to look at the property not to go
stomping over the hard disk.

You did not even have to ask permission to peek at the property, since
user.dir is not a protected property.

aHa............... Would the following do the trick?

// Do what you will
grant {
permission java.security.AllPermission;
};
