e219. Creating a New Policy File

Use policytool to create or edit an existing policy file. This is an example of a policy file created using policytool. It grants two permissions. It grants code signed by Duke permission to read files located in the user's home directory. It also grants code from the location http://someserver/myjar.jar (regardless of who signed it) to read the file.encoding system property.
    > policytool -file .policy
    
    keystore ".keystore";
    grant signedBy "Duke"  {
          permission java.io.FilePermission "${user.dir}/-", "read";
    };
    grant codeBase "http://someserver/myjar.jar" {
        permission java.util.PropertyPermission "file.encoding", "read";
    }
