Question

我想在C:\Dev\SSIS 70.23 C:\Dev\SSIS\DatabaseCleanup 17.80 C:\Dev\SSIS\DatabaseMaintTests 22.91 C:\Dev\SSIS\EclipseKeys 1.22 C:\Dev\SSIS\TemplateProject 13.29中运行applet。我的项目目录具有以下结构：

appletviewer

AppletDocumentLoader是我的项目，然后在/home/sanctus/workspace/AppletDocumentLoader/bin/com/examples/ti中有3个类文件和HTML文件即。全部在同一目录中。

我的src课程

/bin/com/examples/ti

我的HTML文件

package com.examples.ti;
import java.applet.AppletContext;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.lang.reflect.InvocationTargetException;
import java.net.MalformedURLException;
import java.net.URL;

import javax.swing.JApplet;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.SwingUtilities;

public class Applet extends JApplet {

    private static final long serialVersionUID = -8756947240188460854L;


    public void init() {
        try {
            SwingUtilities.invokeAndWait(new Runnable() {

                @Override
                public void run() {
                    JLabel label = new JLabel("Hello World");
                    add(label);
                    JButton openDocument = new JButton();
                    openDocument.setText("Button");
                    openDocument.addActionListener(new ActionListener() {

                        @Override
                        public void actionPerformed(ActionEvent e) {
                            System.out.println("BUTTON CLICKED");
                            AppletContext appletContext = getAppletContext();
                            try {
                                appletContext
                                        .showDocument(
                                                new URL(
                                                        "http://www.google.com"),
                                                "_self");
                            } catch (MalformedURLException e1) {
                                e1.printStackTrace();
                            }

                        }
                    });
                    add(openDocument);
                }
            });
        } catch (InvocationTargetException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}

我得到的错误：

<html>

  <title>Hi there</title>

<body>
  This is a page
  a simple page
</body>
<applet code="Applet.class"

        width=350 height=350>
</applet>
</html>

Answer 1

applet标记的code参数应该是Java类的全名，因此com.examples.ti.Applet。见Applet code tags and class files

Appletviewer抛出java.lang.NoClassDefFoundError异常
