java链接access数据库只能读数据不能添加数据？？

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;

public class MyTest {

private static String DRIVER = "sun.jdbc.odbc.JdbcOdbcDriver";
private static String URL = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=words.mdb";


public static void main(String[] args) throws Exception {
    // TODO Auto-generated method stub

    Class.forName(DRIVER);

    Connection con = DriverManager.getConnection(URL, "", "");
    if (con != null) {
        System.out.println("con is not null");
    } else {
        System.out.println("con is null");
    }

     String sql = "insert into stu(name,sex) values (1,1)";
     PreparedStatement pre = con.prepareStatement(sql);
     pre.executeUpdate();

}

}

应该是没有提交更改，你操作完后把conn关掉试试[/b][/color]

看看access数据库对应的目录文件

是否对任何人开放了写权限
