关于JAVA用ODBC连接MYSQL的代码

下面是我想用ODBC连接MYSQL的代码，我想可能是“org.gjt.mm.mysql.Driver”，“jdbc:odbc:pk”这两个的问题，代码我是不是写错了，
ODBC的驱动我也装了，名字是：mysql-connector-odbc-3.51.20-win32.msi
import java.sql.*;

class JDBCConnection {  
  static {   
    try {      
        Class.forName("org.gjt.mm.mysql.Driver");
        }   
    catch (Exception e)
   {      
        e.printStackTrace();   
    }      
  }  
  JDBCConnection()
  {
      try {
        Connection conn = DriverManager.getConnection("jdbc:odbc:pk");
         Statement stm=conn.createStatement();

        ResultSet rst=stm.executeQuery("select * from dongdong");
        while(rst.next())
        {
           String str1=rst.getString(1);
            String str2=rst.getString(2);
      
            System.out.println(str1+"\t\t"+str2);
        }
        rst.close();
        System.out.println("连接数据库成功...");
        conn.close();
     }
     catch (SQLException e)
     {
        e.printStackTrace();
     }  
  }
}
class MainClass
{
    public static void main(String[] args)
    {   
        new JDBCConnection();
    }
}
