I have added a new file path but when I try to use with IFSAPP am seeing the following error message:

Java call terminated by uncaught Java exception: java.security.AccessControlException: the Permission (java.io.FilePermission \\vm-ftp-02\HORIZON$\TEST\Outgoing\Customer read) has not been granted to IFSAPP. The PL/SQL to grant this is dbms_java.grant_permission( 'IFSAPP', 'SYS:java.io.FilePermission', '\\vm-ftp-02\HORIZON$\TEST\Outgoing\Customer', 'read' )

Using SYS, I have run the PL/SQL as the message suggests but its still not working - any ideas?
