If it is useful from you, i succeded sending files through multiparts forms
in this way:
File aux = new File ("c:\\anyFILE");
HttpClient httpclient = new HttpClient();
PostMethod filePost = new PostMethod(urlCompleta);
filePost.setDoAuthentication(true);
Part[] parts = {new FilePart(aux.getName(), aux)};
filePost.setRequestEntity(new
MultipartRequestEntity(parts, filePost.getParams()));
httpclient.getHttpConnectionManager().getParams().setConnectionTimeout(5000);
int status = httpclient.executeMethod(filePost);
if (status == HttpStatus.SC_OK) {
logger.info("sending OK...");
} else {
logger.info("sending ERROR...");
}
