我编写了一个类 [如大多数教程所示] 来连接 Access 2010 数据库

    package dataBase;

    import java.sql.Connection;
    import java.sql.DriverManager;
    import java.sql.ResultSet;
    import java.sql.SQLException;
    import java.sql.Statement;

    public class connection 
    {
         static Connection conn;
         ResultSet res;
         Statement stat;

         public Connection makeConn() throws ClassNotFoundException, SQLException
         {
             Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
             conn = DriverManager.getConnection("jdbc:odbc:TestDriver:sampleDb");
             return conn;
         }

         public void closeconn() throws SQLException
         {
             conn.close();
         }

          public void Search() throws ClassNotFoundException, SQLException
          {
              stat=conn.createStatement();
              res=stat.executeQuery("select * from table");
              while(res.next())
              {
                  System.out.println(res.getString("id"));
              }
          }
    }

这里TestDriver = 用户 DSN Microsoft Access 驱动程序 sampleDb = 位于我桌面上的 Microsoft Access Db

我的 access 2010 是 64 位的，我在 64 位机器上运行它，我的环境是 eclipse galileo

当我尝试运行它时，我收到以下错误
