Any feasible solution ?


 PreparedStatement stmnt =conn.prepareStatement("insert into
grms_photogallary (user_id,oid) values (?,?)");
       // Set parameters
     String userId="soms";
        stmnt.setString(1, userId);
        File file = new File("/jigsaw/jigsaw/www/easilogo.gif");
  InputStream  photoIn=new FileInputStream(file);

  int size=photoIn.available();

  String str="";
  for(int i=0;i<size;i++)
  {
         str+=(char)photoIn.read();
  }
