public void insertImage(Connection conn,String img) 
     { 
       int len; 
       String query; 
       PreparedStatement pstmt; 

       try 
       { 
         File file = new File(img); 
         FileInputStream fis = new FileInputStream(file); 
         len = (int)file.length(); 

         query = ("insert into TableImage VALUES(?,?,?)"); 
         pstmt = conn.prepareStatement(query); 
         pstmt.setString(1,file.getName()); 
         pstmt.setInt(2, len); 

         // Method used to insert a stream of bytes 
         pstmt.setBinaryStream(3, fis, len); 
         pstmt.executeUpdate(); 

       } 
       catch (Exception e) 
       { 
         e.printStackTrace(); 
       } 
     } 

     public void getImageData(Connection conn) 
     { 

       byte[] fileBytes; 
       String query; 
       try 
       { 
         query = "select data from tableimage"; 
         Statement state = conn.createStatement(); 
         ResultSet rs = state.executeQuery(query); 
         if (rs.next()) 
         { 
            fileBytes = rs.getBytes(1); 
            OutputStream targetFile= 
            new FileOutputStream(
             "d://filepath//new.JPG"); 

            targetFile.write(fileBytes); 
            targetFile.close(); 
         }   

       } 
       catch (Exception e) 
       { 
         e.printStackTrace(); 
       } 
     }
