Re: jdbc mysql: encoding utf-8 to latin1?

well I tried:

                  Class.forName("com.mysql.jdbc.Driver").newInstance();

                  if(this.dbLoginTimeOut != null){
                          DriverManager.setLoginTimeout(this.dbLoginTimeOut.intValue() );
                  }

                  //Properties info = new Properties();
                  //info.put("user", this.dbuser);
                  //info.put("password", this.dbpwd);
                  //info.put("charSet", this.strEnCodingToFromDB); //"utf-8");
                  //info.put("characterEncoding",this.strEnCodingToFromDB);

                  //conn = DriverManager. getConnection(this.dburl, info);

                  conn =
DriverManager.getConnection(this.dburl,this.dbuser,this.dbpwd);

                  stmt = conn.createStatement();

                  //change chars
                      Charset latin1 = Charset.forName("ISO-8859-1");
                      byte[] b = strRequest.getBytes(latin1);
                      System.out.println("strRequest.getBytes(latin1) : ");
                      for (int i = 0; i< b.length; i++) {
                          System.out.printf("%X ", b[i]);
                        }
                      System.out.println("new String(b, latin1) : " + new String(b,
latin1));

                  resultSet = stmt.executeQuery(new String(b, latin1));

is there something wrong? well I have completely no effect in database. The
system.out is correct.
