This should work, I havent tested the code though.

 import org.apache.http.HttpEntity;
    import org.apache.http.HttpResponse;
    import org.apache.http.client.HttpClient;
    import org.apache.http.client.methods.HttpPost;
    import org.apache.http.entity.mime.MultipartEntity;
    import org.apache.http.entity.mime.content.FileBody;
    import org.apache.http.entity.mime.content.StringBody;
    import org.apache.http.impl.client.DefaultHttpClient;

    ...

        public static void uploadFile() throws Exception {
            HttpClient httpclient = new DefaultHttpClient();
            try {
                HttpPost httppost = new HttpPost(uri);
                String pathToOurFile = root+"111";

                File f = new File(pathToOurFile);
                FileBody bin = new FileBody(f);


                MultipartEntity reqEntity = new MultipartEntity();
                reqEntity.addPart("file", bin);
                reqEntity.addPart("paramName", paramValue);

                httppost.setEntity(reqEntity);

                HttpResponse response = httpclient.execute(httppost);
                HttpEntity resEntity = response.getEntity();

                String postResponse = response.getStatusLine();
        }

    }

i am using the above code .but FileBody and MultipartEntity want to create a class.have u used any jar file here.Thanq for u'r reply

for other people who get here and need the libraries: hc.apache.org/downloads.cgi to download httpclient with the missing libraries, you can take just the httpmime jar from that library into your project

also getStatusLine gives you StatusLine which you then have to convert to string
