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

我做错了什么?
