Apply the security policy for applet

I have written one applet file to read the text file from local machine. I have embedded that applet into HTML file. While running the HTML file the error shows like: 

access denied (java.io.FilePermission d:\test.txt)

Then I have written one policy file and place in the jre/lib/security/. Now also it shows the same error. Should I register that applet with policy file, or do I need to do any other steps? Please explain clearly how to solve this issue.

Should I register that applet with policy file,..

No.

.. or do I need to do any other steps?

Instead of doing the stuff using policy files, digitally sign the applet. It is the only practical way to get permissions to access a File for an applet deployed over the internet. (And if it is not deployed from a web page, the question would be 'So why is it an applet?') See Signing and Verifying JAR Files for more details.

Of course, if you can deploy in a Plug-In 2 JRE, the applet can be sand-boxed and the user can still open resources from the local file system.
