Mark, As far as I know, WSDL does not have any sort of mechanism for describing attachments... hence each vendors slightly different implementation of an attachments interface. Your client (or server for that matter) will have to be aware that an attachment is present and attempt to extract it from the attachment parts.
BTW... I am assuming you are attempting to make your web service work with multiple platforms? Are you attempting to use non-Java clients with axis at any point? -----Original Message----- From: Mark Mueller [mailto:[EMAIL PROTECTED]] Sent: Monday, January 27, 2003 4:32 PM To: [EMAIL PROTECTED] Subject: RE: Interoperative attachments Josh, This was very helpful -- thanks a lot! I've implemented my service this way, and I return the URL of the attachment content-id as the return-value of the call. I have another question. The WSDL created by Java2WSDL doesn't mention the file that I return as an attachment. Should I revise the WSDL by hand so that the binding includes something like this: <mime:multipartRelated> <mime:part> <soap:body parts="body" use="literal"/> </mime:part> <mime:part> <mime:content part="file" type="audio/x-wav"/> <mime:part> Do I need some sort of mime stuff in the binding section for my server to work with a variety of clients?
