Comment télécharger une image sur le serveur dans BlackBerry?

Question

Je suis nouveau dans le développement Blackberry et je dois télécharger mon image de la galerie de l'appareil au serveur. J'ai trouvé beaucoup de liens liés à ce point. Mais je ne peux pas trouver le résultat exact de ce problème. J'ai utilisé ce Example. En utilisant cet exemple, j'ai trouvé la valeur dans Byte [] mais je ne suis pas capable de répondre à mes besoins en utilisant ce code. En cela je ne suis pas capable de comprendre quelle URL nous devons passer dans le code et quels sont les paramètres.

J'ai utilisé un format de plus, je poste mon code ici, en utilisant ceci j'ai obtenu le code de réponse: 200. Mais je ne suis pas en mesure de résoudre cela

HttpConnection oCon = (HttpConnection)Connector.open("http://74.208.77.106/jm/testing/iDaddyapi.php;deviceside=true;interface=wifi"); 
       oCon.setRequestMethod(HttpConnection.POST); 
       oCon.setRequestProperty("Content-Length", "" + imageByte.length); 

       URLEncodedPostData oPostData = new URLEncodedPostData(URLEncodedPostData.DEFAULT_CHARSET, false); 

       oPostData.append("api", "postidaddyimage"); 
       oPostData.append("imagetype", "F"); 
       oPostData.append("image", strImage); 

       OutputStream strmOut = oCon.openOutputStream(); 
       strmOut.write(oPostData.getBytes()); 

       strmOut.flush(); 
       strmOut.close(); 



    int rc = oCon.getResponseCode(); 
    System.out.println("Response code.............."+rc); 
    if (rc != HttpConnection.HTTP_OK) 
        throw new IOException("Error response code: " + rc); 

Quelqu'un peut-il m'aider? Je suis coincé là-dessus.

Merci, Mansi

HttpConnection conn = (HttpConnection) Connector.open(Url, Connector.READ_WRITE); 

conn.setRequestProperty(HttpProtocolConstants.HEADER_CONTENT_LENGTH, 
      String.valueOf(imagedata.length)); 

conn.setRequestProperty("x-rim-transcode-content", "none"); 
ByteArrayOutputStream out = new ByteArrayOutputStream(); 
OutputStream finalOut = conn.openOutputStream(); 

String newLine = "\r\n"; 
out.write(newLine.getBytes()); 
out.write("--".getBytes()); 
out.write(boundary.getBytes()); 
out.write(newLine.getBytes()); 
String contDisp = "Content-Disposition:form-data; 
name=\"file\";filename=\"Image.jpg\""; 
String contEnc = "Content-Transfer-Encoding: binary"; 
String type = "Content-Type:image/jpeg"; 
out.write(contDisp.getBytes()); 
out.write(newLine.getBytes()); 
out.write(type.getBytes()); 
out.write(newLine.getBytes()); 
out.write(contEnc.getBytes()); 
out.write(newLine.getBytes()); 
out.write(newLine.getBytes()); 
out.write(imagedata); 
out.write(newLine.getBytes()); 
out.write("--".getBytes()); 
out.write(boundary.getBytes()); 
out.write("--".getBytes()); 
out.write(newLine.getBytes()); 
finalOut.write(out.toByteArray()); 

out.flush(); 
out.close(); 

finalOut.flush(); 
finalOut.close();
