尝试连接MySQL

[DCCC1234]

代码：
package DBTest;

import java.sql.*;

public class DBTest {
public static void main(String[] args) {
String driver = "com.mysql.jdbc.Driver";
String url = "jdbc:mysql://localhost:3306/AddressBook";
String user = "root";
String password = "123456";
try {
Class.forName(driver);
Connection conn = DriverManager.getConnection(url, user, password);

if(!conn.isClosed())
System.out.println("数据库连接成功！");
conn.close();
}
catch(ClassNotFoundException e) {
System.out.println("找不到驱动程序");
e.printStackTrace();
}
catch(SQLException e) {
e.printStackTrace();
}
}
}

出现如下错误

Exception in thread "main" java.lang.NoClassDefFoundError: org/aspectj/lang/Sign
ature

加入相应的驱动包没有？

我把mysql-connector-java-3.1.10-bin放在j2sdk1.4.2_04\jre\lib\ext目录下了
mysql也装好了呀
