如何在网页中嵌入 Java 小程序? [英] How to embed a Java applet in a web page?

问题描述

我正在使用以下代码在网页中嵌入 Java 小程序，

I am using the following code to embed a Java applet in a web page,

<APPLET CODE="main.class" WIDTH=500 HEIGHT=80 archive='testing.jar'>
</APPLET>

但问题是，我的小程序的类文件在一个名为 environment 的包中，这意味着我的 main.class 在文件夹环境中.

But the problem is, the class file for my applet is in a package named environment, which means my main.class is inside a folder environment.

浏览器显示我使用时无法搜索我的类文件的错误信息

The browser show me the error message that it can't search my class file when I use

CODE="main.class"

如何将其设置为在导出的 jar 文件中引用包中的类文件?

How can I set it to refer the class file in a package in the jar file which I export out?

推荐答案

你可能想看看 部署小程序 和 使用 Applet 标签部署.这是小程序的一个小工作示例，可能会对您有所帮助.该页面的 HTML 很简单:

You'll probably want to take a look at Deploying an Applet and Deploying With the Applet Tag. Here's a small working example of an applet that might help you. The HTML for that page is simply:

<applet width="200" height="200" archive="ImageIconApplet.jar"
        code="com.whitefang34.ImageIconApplet" /> 

小程序源代码为:

package com.whitefang34;

public class ImageIconApplet extends JApplet {
    public void init() {
        URL url = getClass().getResource("/images/WhiteFang34.jpg");
        ImageIcon icon = new ImageIcon(url);
        JLabel label = new JLabel(icon, JLabel.CENTER);
        add(label);
    }
}

小程序的打包的jar包含:

/com/whitefang34/ImageIconApplet.class
/images/WhiteFang34.jpg
