Whats correct way to use multicall method of magento SOAP API?

Question

I have implemented two ways to call magento methods, first with http://sudzc.com/ classes and second with http://www.wsdl2code.com/Pages/Home.aspx classes. but not getting product info by either way.

Please check two pairs of request and response for multi call method :-
