We recommend that you discard httpclient and use HttpURLConnection:

Import java. io. byteArrayOutputStream; import java. io. dataOutputStream; import java. io. file; import java. io. fileInputStream; import java. io. IOException; import java. io. inputStream; import java.net. httpURLConnection; import java.net. URL; import java. util. hashMap; import java. util. list; import java. util. map; public class HttpConnector {public static final int TIMEOUT_MS = 10*1000; public static String extends mrequest (String url, File file, Map
  
   
AdditionalHeaders) {String response = null; try {HashMap
   
    
Map = new HashMap
    
     
(); If (additionalHeaders! = Null) map. putAll (additionalHeaders); URL parsedUrl = new URL (url); HttpURLConnection connection = openConnection (parsedUrl, file); for (String headerName: map. keySet () {connection. addRequestProperty (headerName, map. get (headerName);} int responseCode = connection. getResponseCode (); if (responseCode =-1) {//-1 is returned by getResponseCode () if the response code cocould not be retrieved. // Signal to the caller that something was wrong with the connection. throw new IOException ("cocould not retrieve response code from HttpUrlConnection. ");} String charset =" UTF-8 "; String contentEncoding = null; String contentType = null; for (Map. entry

        HeaderValueList = header. getValue (); if (headerValueList! = Null & headerValueList. size ()> 0) {StringBuffer headerValueSB = new StringBuffer (); for (int I = 0; I 
     
    
   
  

Call: String response = HttpConnector. javasmrequest (uploadUrl, file, null );
