The partnerlink type is defined in wsdl, and the partnerlink is defined by bpel file. So you should define the partnerlink type in wsdl file at first. And for your step3, you said you add 'global partner link... name the link, type.....', yes, you should add parnter link, name the link, but the type, you mean partner link type? It should be choose from your wsdl files by a Dialog, right? not create a new one, just choose from existed.
