When working with external HTTP based services in Java / VAADIN I'm ussualy using very nice JODD Java library specificaly http://jodd.org/doc/http.html

To post attachment to URL as explained in question, simply use something like this:

HttpRequest httpRequest = HttpRequest
        .post("http://server:8080/upload")
        .form(
            "file", new File("c:\\a.jpg.zip")
        );

    HttpResponse httpResponse = httpRequest.send();

HttpRequest is object from JODD library. You can include JODD into maven config e.g. http://jodd.org/download/
