第一次用access2010连不上，大神帮我看看代码吧......

academy.addItemListener(new ItemListener(){

    public void itemStateChanged(ItemEvent e){

        major=new JComboBox();

        try{

            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

            String db = "jdbc:odbc:driver={Microsoft Access Driver(*.mdb,*accdb)};DBQ=C:\\Users\\WFVermouth\\Documents\\NetBeansProjects\\GPA\\database\\绩点计算.accdb";

            Connection conn = DriverManager.getConnection(db);

            Statement stmt = conn.createStatement();

            ResultSet rs = stmt.executeQuery("select "+academy.getSelectedItem()+".MName from "+academy.getSelectedItem());

            while (rs.next()) {  

                major.addItem(rs.getString(1));  

            }

            

        }catch(Exception ex){

            ex.printStackTrace();

        }

    }

});

我是想给ComboBox加个监听器，选项改变后连接数据库让另一个ComboBox添加选项，上面这段代码最后打印出来的错误我也看不懂，感觉跟乱码一样。是哪里出错了啊？
