请问MYSQL 使用连接池功能应如何设置 DRIVERCLASS

Question

      MYSQL使用连接池功能 代码如下：   package com.jdbc.proxool;
 
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
 
import java.sql.Statement;
import java.util.Properties;import org.logicalcobwebs.proxool.ProxoolDriver;
import org.logicalcobwebs.proxool.ProxoolFacade;  
public class proxool { /**
 * @param args
 */
public static void main(String[] args) {
 try{
 Class.forName("org.logicalcobwebs.proxool.ProxoolDriver");
Properties info =new Properties(); 
info.setProperty("proxool.maximum-connection-count","10");
info.setProperty("proxool.house-keep-test-sql","select CURRENT_DATE");
info.setProperty("user","test");
info.setProperty("password","test");
String alias="test";
String driverClass="com.mysql.jdbc.Driver";
String  driverUrl="jdbc.mysql://localhost/proxool?user=test&password=test";
    String url="proxool."+alias+":"+driverClass+":"+driverUrl;
    ProxoolFacade.registerConnectionPool(url,info);
            Connection con=DriverManager.getConnection("proxool.test");
            Statement stat =con.createStatement();
            ResultSet rs=stat.executeQuery("select * from student");
            System.out.println(" 客户   年龄    性别  ");
            
            while(rs.next()){
              int id =rs.getInt(1);
              String age=rs.getString(2);
              String sex=rs.getString(3);
              System.out.println(id+"   "+age+"   "+sex);
            }     
 }
       catch(Exception e){
        System.out.println(e.getMessage());
        
       }
}}
所需的驱动类已经加载：COMMONS-LOGGIN.JAR;PROXOOL.JAR;MYSQL-CONNECTOR-JAVA.JAR
 报错如下：
2009-11-2 18:16:10 org.logicalcobwebs.proxool.ProxoolFacade registerConnectionPool

请问DRIVERCLASS 应如何配置 需要加newInstance()吗 ？
谢谢！
