academy.addItemListener(new ItemListener(){<br />
    public void itemStateChanged(ItemEvent e){<br />
        major=new JComboBox();<br />
        try{<br />
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");<br />
            String db = "jdbc:odbc:driver={Microsoft Access Driver(*.mdb,*accdb)};DBQ=C:\\Users\\WFVermouth\\Documents\\NetBeansProjects\\GPA\\database\\绩点计算.accdb";<br />
            Connection conn = DriverManager.getConnection(db);<br />
            Statement stmt = conn.createStatement();<br />
            ResultSet rs = stmt.executeQuery("select "+academy.getSelectedItem()+".MName from "+academy.getSelectedItem());<br />
            while (rs.next()) {  <br />
                major.addItem(rs.getString(1));  <br />
            }<br />
            <br />
        }catch(Exception ex){<br />
            ex.printStackTrace();<br />
        }<br />
    }<br />
});

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？
