Upload through HTTP with attachments - multipart/mixed - rfc 2046

[Ettoregia <et...@gmail.com>]

Hi all,

I've been looking for clues for quite a while now, and given the poor
results, I thought it's time to ask 
the community.

I'm trying to create an http request to be in the format reported below with
Camel 2.12 within Jboss Fuse 6.1.  
Below is my attempt, which produces "Sent to server" also reported below.

So I can see that although I set the Content-type header to be 
"multipart/mixed", that is not set on server side. One more thing, I thought
and I have to, have the second part of the http message to be sent as an
attachment, but when I try to exchange.getIn().getAttachments() that is
always null.

Please if you find some time would you at least give an hint on that, I'm at
my wits end...

Thanks in advance.

		post.addHeader("Content-Type", "multipart/mixed");
		post.setEntity(entity);

		HttpClient httpclient = HttpClientBuilder.create().build();

		HttpResponse response = httpclient.execute(post);
