wsdl, attachment

Thu, 16 Feb 2006 07:59:11 -0800 

Hi all (again :)
I would like to write such a service method, that can get receive binary files (so it can recieve soap attachments). I tested the sample service sample/attachments (like Simone and Fabricio http://marc.theaimsgroup.com/?l=axis-user&m=113940005201713&w=2), it works (also the hand written client), but when trying to create client from the wsdl WSDL2java throws an exception that DataHandler is not defined (and it is really not deined). Is there possibility to create a webmethod, from that the generated wsdl contains also the attachment informations? Or Is it always better to use the generated wsdl as a template, so always to insert the attachment information into it? 
I use Axis 1.3

Thnx for the help
 George
