Console don't let my applet run because of a file

I am working in an applet. It works perfect with Eclipse but when I try to run from Console it gives me this stack trace:

C:\Course Technology\src>appletviewer TestJAlienHunt.html

Path for file entered D:\Course Technology\AssignmentFinal\scoreFile.txt java.security.AccessControlException: access denied ("java.io.FilePermission" "D:\Course Technology\AssignmentFinal\scoreFile.txt" "read")

The file has permission to read and write, why I am getting this?

An applet needs to be digitally signed by you and trusted by the end user before it can access the local file system on the user's computer.

I highlight user's computer because that is where any File will equate to. There is no option for getting a File pointing to the server. If this is read only and the server hosts the resource, access it by URL.
