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 aFile
pointing to the server. If this is read only and the server hosts the resource, access it byURL
.
