如何在jar文件中制作Frame / Applet应用程序？
[英]How can I make Frame/Applet application in jar file?
问题描述
I have a sample code App.java : 
我有一个示例代码App.java ：
import javax.swing.*;
import java.awt.*;
public class App extends JApplet
{
public void init()
{
getContentPane().add(new JLabel("App"));
}
public static void main(String[] args)
{
JApplet aplet = new App();
JFrame frame = new JFrame("App");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(aplet);
frame.setSize(300,300);
aplet.init();
aplet.start();
frame.setResizable(false);
frame.setVisible(true);
}
}
I compile it by means of compile.bat : 我通过compile.bat ：
@echo off
cls
del *.jar
javac *.java
jar cfe App.jar App *.class
del *.class
When I double click on App.jar , I see a frame with text. 当我双击App.jar ，我看到一个带有文本的框架。 That is what I wanted. 那就是我想要的。
How can I also display this on a html page? 如何在html页面上显示呢？
I try code below and it doesn't work: 我尝试下面的代码，它不起作用：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<title>App</title>
</head>
<body>
<center>
<h1>App</h1>
<applet codebase="classes" code="App.class" archive="App.jar
width="300" height="300" " />
</center>
</body>
</html>
The page shows Error. Click for details. 该页面显示Error. Click for details. Error. Click for details. When I click, I see: 当我单击时，我看到：
load: class App.class not found.
java.lang.ClassNotFoundException: App.class
at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source)
at sun.plugin2.applet.Plugin2ClassLoader.loadClass0(Unknown Source)

at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
Exception: java.lang.ClassNotFoundException: App.class
When I post App.class on html, everything works. 当我在HTML上发布App.class时，一切正常。 I'm unable to post App.jar . 我无法发布App.jar 。 How can I do this so it works both as an applet and frame? 我该怎么做，使其既可以作为小程序又可以作为框架？

我刚刚从html删除了codebase="classes" ，一切正常:)。
