Java.security.AccessControlException when accessing user documents

Question

Hello there,
I'm a student programmer. I'm trying to write a desktop application which will read all of the user's documents folder and add it to a ZIP file. I am coding on Windows Vista but my code should be platform independent.
The problem I have is that whenever I try to access the user documents, I get a java.security.AccessControlException. The code I'm using follows:
//Find out the user's "My Documents" folder
javax.swing.JFileChooser fr = new javax.swing.JFileChooser();
javax.swing.filechooser.FileSystemView fw=fr.getFileSystemView();
//Zip the contents of "My Documents" to the current working directory
zip(fw.getDefaultDirectory().toString() + "\\", "JemsFrom.zip")
//Checking for permissions for reading source       
FilePermission perm = new FilePermission(source, "read");
AccessController.checkPermission(perm);I Googled and apparently I need to add a policy file allowing my program access to the documents folder. I created the following policy file:
grant {
      permission java.io.FilePermission "C:\\Users\\keith\\Documents", "read";
};I saved this file as 'perms' and then added the following to Netbeans' Argument list for this project:
-Djava.security.manager -Djava.security.policy=permsHowever, I am still getting this error and am totally stumped. I've also tried running this project outside Netbeans with those arguments but I get the same result.
Would greatly appreciate any help.

I have changed my permissions file as david_david suggested, but I am still having the same problem... AccessControlException
Any other helpful suggestions would be welcome.
