    - 测试
      - 测试$ 1.class
      - 的Test.class

page.html中：

            Applet failed to run.  No Java plug-in was found.
        </object>

Test.java：

package com.tyilo.Test;

import java.awt.Graphics;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.security.AccessControlException;
import javax.swing.JApplet;

public class Test extends JApplet
{

    private static final long serialVersionUID = 1L;

    public String text;

    @Override
    public void init()
    {   
        text = "~/test.txt created successfully!";
        try
        {
            FileWriter fstream = new FileWriter(System.getProperty("user.home") + "/test.txt");
            BufferedWriter out = new BufferedWriter(fstream);
            out.write("Testing123");
            out.close();
        }
        catch(AccessControlException e)
        {
            text = "File permission error.";
        }
        catch(Exception e)
        {
            text = "Unknown error: " + e.getMessage();
        }
    }

    @Override
    public void paint(Graphics g)
    {
        g.drawString(text, 50, 30);
    }

    @Override
    public void start()
    {
        //TODO
    }

    @Override
    public void stop()
    {
        //TODO
    }

    @Override
    public void destroy()
    {
        //TODO
    }
}

chrome中的Java控制台错误：

java.lang.ClassNotFoundException: com.tyilo.Test.Test

修改代码似乎在最新的稳定版本的chrome中运行良好，所以这可能只是金丝雀版本中的错误。

修改2

在本地运行html（和jar）时，chrome只有一个问题。

Answer 1

我建议使用deployjava.js http://docs.oracle.com/javase/6/docs/technotes/guides/jweb/deployment_advice.html

Answer 2

在chrome中启用java，为此，键入javascript：if（browser.value.getIndex（“chrome”）{chrome.browser.enableFeature（JApplet）}）; in to chrome

Java applet适用于appletviewer，Safari和Firefox，但不适用于Chrome
