Can'；在Eclipse中使用javascript代码从html显示小程序

我尝试使用Eclipse IDE中的javascript代码运行java小程序，如网页所示。但是输出页面显示错误。我使用applet的代码是

<script src="//www.java.com/js/deployJava.js"></script>

试试下面的代码

 <APPLET CODE=AppletSubclass.class WIDTH=anInt HEIGHT=anInt>
 </APPLET>

或

试试这个

Java小程序

包cdig；
导入java.applet.applet；
导入java.security.AccessController；
导入java.security.PrivilegedAction；
公共类CDigApplet扩展Applet
{
私有静态最终长serialVersionUID=1L；
字符串ret；
CDigApplet applet=this；
@SuppressWarnings（{“rawtypes”，“unchecked”}）
公共字符串签名文件（字符串文件ID、字符串pin、字符串令牌）
{
AccessController.doPrivileged（新的PrivilegedAction（）
{
@凌驾
公共对象运行（）
{
尝试
{
System.out.println（“协助程序”）；
}
捕获（例外e）
{
字符串sl=“{\'success\”：false，“+”消息\“：\”+e.getMessage（）+“\”}”；
ret=sl；
系统输出打印LN（sl）；
}
返回null；
}
});
返回ret；
}
公共void init（）{
}
公共空间销毁（）{
}
}

谢谢您的回复，但它不起作用。结果相同，只是小程序空间中显示了一个错误

This is the list of exceptions that occurred launching your applet. Please note, those exceptions can originate from multiple applets. For a helpful bug report, be sure to run only one applet.
