Problem displaying picture stored in mySQL

Question

Hi, i just have got problem displaying picture stored in database as BLOB and presented on JSP over servlet. Below is my code i am using to upload file into database, than download it and display again. The result is the picture can not draw inself and there is always only empty picture space on the web page i am displaying. Please help me to find why it is not working, thanx.
servlet uploading picture to database
               boolean isMultipart = FileUpload.isMultipartContent(req);
               DiskFileUpload upload = new DiskFileUpload();
               List items = upload.parseRequest(req);
               Hashtable textFields = new Hashtable();
               byte[] data = new byte[4096];
               if(isMultipart)
                    Iterator iter = items.iterator();
                    while(iter.hasNext())
                         FileItem item = (FileItem)iter.next();
                         if(item.isFormField())
                              textFields.put(item.getFieldName(), item.getString());
                         }else{
                              data = item.get();
               String sqlStatement = "INSERT INTO cds VALUES('" textFields.get("id")"'," +
                                        "'" textFields.get("album") "','" textFields.get("interpreter") "'," +
                                                  "'" textFields.get("gr1") "','" textFields.get("gr2") "','" textFields.get("price") "')";
               String sqlStatement2 = "INSERT INTO pics VALUES('" textFields.get("id") "','" data "')";
servlet to download picture
String SQL =
     "SELECT Picture " +
     "FROM pics " +
     "WHERE id = '" + request.getParameter("id") + "'";
     ResultSet rs = stmt.executeQuery(SQL);
     rs.next();
     Blob blob = null;
     blob = rs.getBlob(1);
     response.setContentType("image/jpg");
     request.setAttribute("blob", blob);
     System.out.println("just above OutputStream");
     InputStream in = blob.getBinaryStream();
     ServletOutputStream sout = response.getOutputStream();
     int b;
     while ((b = in.read()) != -1) {
     sout.write(b);
     in.close();
     sout.flush();
     sout.close();
