I have a server to upload file the server info is

<form action="FileUpload" method="post" enctype="multipart/form-data"> Select File <input type="file" name="file1"> <p> Select Filename <input type="text" size="20" name="filename"> <p> <input type=submit value="Upload"> </form>

I am uploading file using below code

private boolean doFileUpload ( ) { boolean success = false ; HttpURLConnection conn = null ; DataOutputStream dos = null ; DataInputStream inStream = null ; String exsistingFileName = filePath ; String lineEnd = "\r\n" ; String twoHyphens = "--" ; String boundary = "*****" ; int bytesRead , bytesAvailable , bufferSize ; byte [ ] buffer ; int maxBufferSize = 1 * 1024 * 1024 ; String responseFromServer = "" ; String urlString = "http://paperify.net/tripmark/FileUpload" ; try { // ------------------ CLIENT REQUEST Log.e ( "MediaPlayer" , "Inside second Method" ) ; FileInputStream fileInputStream = new FileInputStream ( new File ( exsistingFileName ) ) ; // open a URL connection to the Servlet URL url = new URL ( urlString ) ; // Open a HTTP connection to the URL conn = ( HttpURLConnection ) url.openConnection ( ) ; // Allow Inputs conn.setDoInput ( true ) ; // Allow Outputs conn.setDoOutput ( true ) ; // Don't use a cached copy. conn.setUseCaches ( false ) ; // Use a post method. conn.setRequestMethod ( "POST" ) ; conn.setRequestProperty ( "Connection" , "Keep-Alive" ) ; conn.setRequestProperty ( "action" , "FileUpload" ) ; conn.setRequestProperty ( "file" , "myfile" ) ; conn.setRequestProperty ( "value" , "Upload" ) ; conn.setRequestProperty ( "Content-Type" , "multipart/form-data;boundary=" + boundary ) ; dos = new DataOutputStream ( conn.getOutputStream ( ) ) ; dos.writeBytes ( twoHyphens + boundary + lineEnd ) ; dos.writeBytes ( "Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + exsistingFileName + "\"" + lineEnd ) ; dos.writeBytes ( lineEnd ) ; Log.e ( "MediaPlayer" , "Headers are written" ) ; // create a buffer of maximum size bytesAvailable = fileInputStream.available ( ) ; bufferSize = Math.min ( bytesAvailable , maxBufferSize ) ; buffer = new byte [ bufferSize ] ; // read file and write it into form... bytesRead = fileInputStream.read ( buffer , 0 , bufferSize ) ; while ( bytesRead > 0 ) { dos.write ( buffer , 0 , bufferSize ) ; bytesAvailable = fileInputStream.available ( ) ; bufferSize = Math.min ( bytesAvailable , maxBufferSize ) ; bytesRead = fileInputStream.read ( buffer , 0 , bufferSize ) ; } // send multipart form data necesssary after file data... dos.writeBytes ( lineEnd ) ; dos.writeBytes ( twoHyphens + boundary + twoHyphens + lineEnd ) ; BufferedReader in = new BufferedReader ( new InputStreamReader ( conn.getInputStream ( ) ) ) ; String inputLine ; while ( ( inputLine = in.readLine ( ) ) != null ) Log.e ( "Res" , "" + inputLine ) ; // close streams Log.e ( "MediaPlayer" , "File is written" ) ; success = true ; fileInputStream.close ( ) ; dos.flush ( ) ; dos.close ( ) ; } catch ( MalformedURLException ex ) { Log.e ( "MediaPlayer" , "error: " + ex.getMessage ( ) , ex ) ; success = false ; } catch ( IOException ioe ) { Log.e ( "MediaPlayer" , "error: " + ioe.getMessage ( ) , ioe ) ; success = false ; } // ------------------ read the SERVER RESPONSE try { inStream = new DataInputStream ( conn.getInputStream ( ) ) ; String str ; while ( ( str = inStream.readLine ( ) ) != null ) { Log.e ( "MediaPlayer" , "Server Response" + str ) ; } inStream.close ( ) ; } catch ( IOException ioex ) { Log.e ( "MediaPlayer" , "error: " + ioex.getMessage ( ) , ioex ) ; } return success ; }

It did not upload file but give exception below

The 1st line at com.paperify.tripmark.UploadPicture.doFileUpload(UploadPicture.java:141) is 

BufferedReader in = new BufferedReader ( new InputStreamReader ( conn.getInputStream ( ) ) ) ;

I don't know what wrong I am doing.

Use HTTP client. Here is a sample code.

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; import org.apache.http.util.EntityUtils; ... public static void uploadFile() throws Exception { HttpClient httpclient = new DefaultHttpClient(); try { HttpPost httppost = new HttpPost("http://paperify.net/tripmark/FileUpload"); StringBody filename = new StringBody("filename.ext"); File f = new File("src"+File.separator + "filename.ext"); FileBody bin = new FileBody(f); StringBody comment = new StringBody("A binary file of some kind"); MultipartEntity reqEntity = new MultipartEntity(); reqEntity.addPart("file1", bin); reqEntity.addPart("filename", filename); reqEntity.addPart("comment", comment); httppost.setEntity(reqEntity); System.out.println("executing request " + httppost.getRequestLine()); HttpResponse response = httpclient.execute(httppost); HttpEntity resEntity = response.getEntity(); System.out.println("----------------------------------------"); System.out.println(response.getStatusLine()); if (resEntity != null) { System.out.println("Response content length: " + resEntity.getContentLength()); InputStream is = resEntity.getContent(); if (is != null) { Writer writer = new StringWriter(); char[] buffer = new char[1024]; try { Reader reader = new BufferedReader( new InputStreamReader(is, "UTF-8")); int n; while ((n = reader.read(buffer)) != -1) { writer.write(buffer, 0, n); } } finally { is.close(); } System.out.println("Response content: "+writer.toString()); } else { System.out.println("Response nothing: "); } } EntityUtils.consume(resEntity); } finally { try { httpclient.getConnectionManager().shutdown(); } catch (Exception ignore) {} } } }
