            reqEntity.addPart("file1", file1);
            httpPost.setEntity(reqEntity);

                HttpClient httpclient =new DefaultHttpClient();
                httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
//                httpclient.getParams().setParameter(CoreProtocolPNames.HTTP_CONTENT_CHARSET, Charset.forName("UTF-8"));
                httpResponse = httpclient.execute(httpPost);
