在这里从有用的用户那里得到建议后，我对我的代码进行了一些更改。我缺少什么来加载这个驱动程序？有人建议我获取 Jackcess，并将其包含在我的库中。我正在使用 java 8 我没有过去

Connection conn = DriverManager.getConnection(database, "", "");

在它抛出一堆异常之前。

import java.sql.*;
import javax.swing.JOptionPane;
import java.sql.DriverManager;
 private void SubmitActionPerformed(java.awt.event.ActionEvent evt) {                                       

    try {
        String database = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=db1.mdb;";
        Connection conn = DriverManager.getConnection(database, "", "");
        //String driver = "sun.jdbc.odbc.JdbcOdbcDriver";
        //Class.forName(driver);
        // String db = "jdbc:odbc:db1";
        //con = DriverManager.getConnection(db);
        st = conn.createStatement();
        System.out.println("it actually ready this set of code!");
        String un = UserName.getText().trim();
        String pw = Password.getText().trim();
        String sql = "select user,pass from Table2 where user='"+un+"'and pass='"+pw+"'";
        rs=st.executeQuery(sql);
        int count = 0;
        while(rs.next()){
            count = count+1;
        }
        if (count==1){
            JOptionPane.showMessageDialog(null,"User, Found Access Granted!");
        }
        else if (count>1){
            JOptionPane.showMessageDialog(null,"Duplicate User, Access Denied!");
        } 
        else {
            JOptionPane.showMessageDialog(null, "user doesn't exsist. ");
        }

    } catch (Exception ex){
            System.out.println("exception 2, " );
            ex.printStackTrace();
    }

    // TODO add your handling code here:
}

这些是我得到的异常错误：

您正在尝试使用 JDBC 访问数据库。根据Jackcess FAQ，Jackcess 驱动程序不支持 JDBC：

Jackcess 是否为 Microsoft Access 数据库提供 JDBC 驱动程序？

抱歉不行。Jackcess API 是可用于与 Access 数据库交互的功能的直接实现。目前，Jackcess 库中没有包含 JDBC API 的实现。虽然这个库将成为 JDBC 驱动程序的一个很好的基础，但实现 JDBC API 目前超出了这个项目的范围。已经有一些尝试使用 Jackcess 为 Access 数据库构建 JDBC 驱动程序，但大多数项目在变得不活跃之前都没有取得很大进展。然而， UCanAccess 项目是一个当前活跃的开源项目，它提供了一个建立在 Jackcess 之上的 JDBC 驱动程序。
