比如说下面这个编译后,用appletviewer HelloWorldApplet.java可以看到小程序并能显示.但是在网页中只能看待灰色的方快,但是字"Hello World!"显示不出来.那位达人看看是如何的问题.网页的设置吗?//<applet code="HelloWorldApplet.class" width="150" height="50">
//</applet>
//import java.applet.Applet;
import javax.swing.JApplet;
import java.awt.Graphics;
public class HelloWorldApplet extends JApplet
{
public void paint(Graphics g)
{
super.paint(g);
g.drawString("Hello World!",50,25);
}
}

<HTML>

还有这个问题好象不难啊,那位大虾能说说是怎么会事吗?
