JDBC-ODBC桥连接

Question

我正在使用Java学习数据库，下面是简单的代码：

import java.awt.BorderLayout;

import java.awt.Dimension;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.List;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.JTextField;


public class ClassGUIApplication extends JFrame{

private JPanel centerPnl = new JPanel();
private JPanel northPnl = new JPanel();
private JLabel idLbl = new JLabel("Id:");
private JLabel nameLbl = new JLabel("Name:");
private JLabel surnameLbl = new JLabel("Surname:");
private JLabel gradeLbl = new JLabel("Grade:");
private JTextField idTxt = new JTextField(30);
private JTextField nameTxt = new JTextField(30);
private JTextField surnameTxt = new JTextField(30);
private JTextField gradeTxt = new JTextField(30);
private JButton insertBtn = new JButton("INSERT");
private JTable table;
private StudentDBManager mng = new StudentDBManager();
private ClassTableModel model;
public ClassGUIApplication() {
    setTitle("Class Grade Report");
    setLayout(new GridLayout(2,1));
    centerPnl.setLayout(new GridBagLayout());
    GridBagConstraints gc = new GridBagConstraints();
    gc.gridx = 0;
    gc.gridy = 0;
    centerPnl.add(idLbl, gc);
    gc.gridx = 1;
    gc.gridy = 0;
    centerPnl.add(idTxt, gc);
    gc.gridx = 0;
    gc.gridy = 1;
    centerPnl.add(nameLbl, gc);
    gc.gridx = 1;
    gc.gridy = 1;
    centerPnl.add(nameTxt, gc);
    gc.gridx = 0;
    gc.gridy = 2;
    centerPnl.add(surnameLbl, gc);
    gc.gridx = 1;
    gc.gridy = 2;
    centerPnl.add(surnameTxt, gc);
    gc.gridx = 0;
    gc.gridy = 3;
    centerPnl.add(gradeLbl, gc);
    gc.gridx = 1;
    gc.gridy = 3;
    centerPnl.add(gradeTxt, gc);
    gc.gridx = 2;
    gc.gridy = 4;
    centerPnl.add(insertBtn, gc);
    insertBtn.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {
            int id = Integer.parseInt(idTxt.getText());
            String name = nameTxt.getText();
            String surname = surnameTxt.getText();
            double grade = Double.parseDouble(gradeTxt.getText());
            Student student = new Student(id,name,surname,grade);
            mng.addStudent(student);
            List<Student> classList = mng.getStudents();
            model = new ClassTableModel(classList);
            table.setModel(model);

        }
    });

    northPnl.setLayout(new GridLayout());
    List<Student> classList = mng.getStudents();
    model = new ClassTableModel(classList);
    table = new JTable(model);
    northPnl.add(new JScrollPane(table));

    add(centerPnl);
    add(northPnl);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setPreferredSize(new Dimension(500,500));
    setVisible(true);
    pack();
}

public static void main(String[] args) {
    ClassGUIApplication app = new ClassGUIApplication();
}


}


public static void main(String[] args) {
    ClassGUIApplication app = new ClassGUIApplication();
}


}

Eclipse给出这样的错误：

您的操作系统或JVM是32位还是64位？

我不相信64位JVM具有ODBC桥驱动程序类。 64位操作系统建议您阅读以下内容：

每当遇到错误时，我要做的第一件事就是将其粘贴到Google中。 我通常知道我不是第一个看到我的问题的人。
