我有以下代码用于我的 java swing 应用程序，它在 eclipse IDE 中执行良好，但是当我将它嵌入 HTML 时，不在浏览器中执行，只显示空白框。
Java摇摆代码：
import javax.swing.*;
import java.applet.*;
import java.awt.*;
public class Form extends JApplet{
public void init()
{
JFrame frame = new JFrame("Form");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setResizable(false);
JPanel panel = new JPanel();
JLabel label1 = new JLabel("");
JTextField field = new JTextField(20);
//JButton button1 = new JButton("OK");
//JButton button2 = new JButton("Cancel");
Container c;
c=frame.getContentPane();
c.setLayout(null);
JLabel name=new JLabel("Name :");
JLabel compcode=new JLabel("Company Code :");
JLabel cardno=new JLabel("Card Number: ");

JLabel valupto=new JLabel("Valid Upto :");
JLabel jdate=new JLabel("Joining Date :");
JLabel dept=new JLabel("Department :");
JLabel uid=new JLabel("UID :");
JTextField nametxt=new JTextField(10);

name.setBounds(10, 10, 100, 25);

dept.setBounds(10, 290, 100, 25);
depttxt.setBounds(110, 290, 100, 25);
uid.setBounds(10, 320, 100, 25);
uidtxt.setBounds(110, 320, 100, 25);
//button1.setBounds(10, 50, 75, 25);
//button2.setBounds(10, 70, 75, 25);
c.add(name); c.add(nametxt);
c.add(compcode); c.add(compcodetxt);
c.add(cardno); c.add(cardnumtxt);
c.add(pin); c.add(pintxt);
c.add(bldgrp); c.add(bldgrptxt);
c.add(empcode); c.add(empcodetxt);
c.add(dob); c.add(dobtxt);
c.add(valupto); c.add(valuptotxt);
c.add(jdate); c.add(jdatetxt);
c.add(dept); c.add(depttxt);
c.add(uid); c.add(uidtxt);
//panel.add(button1);
//panel.add(button2);
//frame.add(panel);
frame.setSize(350,400);
//frame.pack();
frame.setVisible(true);
}
}
嵌入它的 HTML 代码如下：
<html>
<head>
<title>Test Page</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<applet Archive ="Form.jar" Code="com.vms.util.Form" WIDTH="250" HEIGHT="300" >
</applet>
</html>
我为我的swing类生成了Form.jar带有包的JAR，com.vms.util
我将它保存在我的D: drive form目录中，并将所有html和jar放在表单目录中。
我可以在 HTML 中运行我的 Swing 应用程序，我该如何运行它？
当我使用 appletviewer 运行上述代码时，出现以下错误
D:\form>appletviewer Form2.html
