You mean that you use two soap calls to get both meta info. and DataHandler?

SOAP with Attachement basically let you "upload" data files and its response does not allow you get data back as a Mime attachment. It's sort of asymmetric process. For me, I deployed both SOAP client and server classes for both sides, let SOAP client (side A)pass the parameters to SOAP server(side B), then SOAP server class(side B) passed parameters to its client class(still side B), then client class(side B) invoke another soap call to sideA. Side A upload Side B (soap client) -------> (soap server) | download V (soap server) <------- (soap client) See illustrate above, hope it helps. -Daniel
