I use Dispatch and got attachments to work inbound/outbound for it. For
outbound, it's basically these steps (carving the relevant lines from my code,
leaving out the rest):
Collection<Attachment> attachments = new LinkedList<Attachment>();
// do a loop here to create your attachments
String id = attachmentEntry.getKey();
AttachmentImpl newAttachment = new AttachmentImpl(id);
attachments.add(newAttachment);
// do a loop to set any headers you have
newAttachment.setHeader(headerName, headerValue);
// there are a couple ways to provide the data for an attachment, I use
a couple of them, but here's the easiest one
byte[] attachmentContent = // your byte content
dataHandler = new DataHandler(new ByteDataSource(attachmentContent,
contentType));
newAttachment.setDataHandler(dataHandler);
// attach that list to your message
dispatch.getRequestContext().put(Message.ATTACHMENTS, attachments);
Do this as about the last thing before you send the message, I recall some sort
of ordering trouble with attachments although maybe that was on the response.
Good luck,
Jesse

Subject: Re: Attachments for Dispatch not supported?
This SHOULD be handled in the WrappedMessageContext, but it looks potentially
incomplete. The "put" is certainly not wired in for the
MessageContext.OUTBOUND_MESSAGE_ATTACHMENTS key. However, it looks like the
get should have returned a viable Map. I guess the suggestion is to breakpoint
in the AttachmentOutInterceptor and see if it's managed to see if an attachment
is there or not.
