Java使用ucanaccess连接Access数据库，报错：UCAExc:::4.0.0 user lacks privilege or object not found: XXXXXX

代码如下：

package com.accord;import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;public class Testes {public static void main(String[] args) throws Exception {Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");// 这个驱动的地址不要改// Connection// con=DriverManager.getConnection("jdbc:ucanaccess://D:\\Database3.mdb","123456","123456");//Connection con = DriverManager.getConnection("jdbc:ucanaccess://D:\\add.mdb","test0011","test0011");Connection con = DriverManager.getConnection("jdbc:ucanaccess://D:\\test.mdb","test0011","test0011");//Connection con = DriverManager.getConnection("jdbc:ucanaccess://src/config/system.mdb","test0011","test0011");Statement stmt = con.createStatement();// 查找数据//ResultSet rs = stmt.executeQuery("select fip from t_sys_dj ");//ResultSet rs = stmt.executeQuery("select distinct FGROUP from t_sys_dj ");//ResultSet rs = stmt.executeQuery("select distinct username from test ");//ResultSet rs = stmt.executeQuery("select DISTINCT FGROUP from T_SY_DJ ");ResultSet rs = stmt.executeQuery("select DISTINCT FGROUP from T_SYS_DJ ");while (rs.next()) {System.out.println(rs.getString("FGROUP"));}// 添加数据/*if (stmt.executeUpdate("insert into test(username) values('李四')") > 0) {System.out.println("添加成功!!!");} else {System.out.println("添加失败!!!");}*///修改/*if (stmt.executeUpdate("update test set username = '李思思' where id = 3 ") > 0) {System.out.println("修改成功!!!");} else {System.out.println("修改失败!!!");}*///删除/*if (stmt.executeUpdate("delete from test where id = 3 ") > 0) {System.out.println("删除成功!!!");} else {System.out.println("删除失败!!!");}*/}
}

报错如下：

报错原因及解决方法：

最好代码中的表名和字段名的大小与.mdb中大小写一致！防止不必要的错误！
