Hi Philippe,

I am using Axis 1.3 (cvs). There are some issues with large attachments,
but they should be fixed in the current 1.3 release, or as far as I
know, by using Commons.HttpSender.
If you are using axis2, I'd suggest you take a look at MTOM
(http://ws.apache.org/axis2/mtom-guide.html)

this is how I do it - works fine for me:
(NOTE: the wsdl will NOT reflect that attachments are being transmitted.)

/***************************
* server - some service:
***************************/
...
// do something meaningful, that produces data
...
// add the output file as attachment
Message response = context.getResponseMessage();
response.getAttachmentsImpl().setSendType(Attachments.SEND_TYPE_DIME);
DataHandler dh = new DataHandler(new FileDataSource(file));
AttachmentPart part = new AttachmentPart(dh);
response.addAttachmentPart(part);
// server - finished

/***************************
* client
****************************
...
// constructor
...
this.YOUR_SERVICE_HERE_Stub = (GENERATED_STUB_SoapBindingStub) new
YOUR_SERVICE_ServiceLocator().getYOUR_SERVICE();
// call web service
MessageContext context =
this.YOUR_SERVICE_HERE_Stub._getCall().getMessageContext();
DataHandler dh = this.extractAttachment(context);
dh.writeTo(os);

Hope that helps,
Tom
