cnchal Can you help me with this? What should I do for it to work? I'm new to USPS and just have the basic knowledge on PHP.

I am on oscommerce-2.2ms2 I have installed this USPS Methods http://addons.oscommerce.com/info/487 but after installing I got this: Warning: main(includes/classes/xml.php) [function.main]: failed to open stream: No such file or directory in /oscommerce.v2.2/catalog/includes/modules/shipping/usps.php on line 15 Fatal error: main() [function.require]: Failed opening required 'includes/classes/xml.php' (include_path='.:/usr/lib/php') in /oscommerce.v2.2/catalog/includes/modules/shipping/usps.php on line 15
