我正在尝试在学校学习基本的SQL测试，但不幸的是，我将本应使用的类复制到了我的PC上的项目中，但出现以下错误：

java.sql.SQLException：[Microsoft] [ODBC驱动程序管理器]找不到数据源名称，也未指定默认驱动程序

package Question1;

// Your name, Q 1
import java.sql.*;
import java.io.*;
import javax.swing.*;

public class GreenWood
{
 // Set up database connection
   private static final String DATABASE_FILE_NAME = "WoodDB.mdb";
   private static final String DRIVER = "jdbc:odbc:DRIVER=" +
   "{Microsoft Access Driver (*.mdb)};" +
   "DBQ=" + new File (DATABASE_FILE_NAME).getAbsolutePath ();
  static
  {
     try
     {
        Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
     }
         catch (ClassNotFoundException e)
        {
           System.out.println ("Class not found");
           e.printStackTrace ();
        }
  }


  private Connection dbcon;
  private BufferedReader keyb = new BufferedReader (new InputStreamReader (System.in));

   public GreenWood ()
  {
     System.out.println ("WoodDB Connection");
     try
     {
        dbcon = DriverManager.getConnection (DRIVER);
        Statement stmt = dbcon.createStatement ();
        System.out.println ("Connection successful\n");

        char choice = ' ';
        do
        {

         //Prints options for user input

           choice = keyb.readLine ().toUpperCase ().charAt (0);
           System.out.println (" ");
           switch (choice)
           {
             //calls query methods based on user input

           }
        }
        while (choice != 'X');
        dbcon.close ();
        System.out.println ("Done");
        Thread.sleep (1000);
        System.exit (0);
     } // try
         catch (Exception e)
        {
        // process exceptions here
           System.out.println ("Connection unsuccessful");
           e.printStackTrace ();
           System.out.println (e.toString ());
        }
  } // HoutSoorte constructor

  //Query Methods
  //Main creates new instance of GreenWood

我的WoodDB数据库位于项目根目录中。

我已经进行了一些故障排除，我相信问题出在驱动程序位置的URL。

dbcon = DriverManager.getConnection (DRIVER);

驱动因素是：

private static final String DRIVER = "jdbc:odbc:DRIVER=" +
   "{Microsoft Access Driver (*.mdb)};" +
   "DBQ=" + new File (DATABASE_FILE_NAME).getAbsolutePath ();

经过大约一个小时的研究，我仍然和以前一样感到困惑。如果有人能用婴儿的语言解释问题以及我如何解决这个问题，可以帮助这个nub程序员，我将不胜感激。
