关于getParameter()方法的问题!

各位大哥好!小弟在使用Applet类的getParameter方法时,无法获取值,我用的是eclipse!代码如下:
package com;

import java.awt.*;
import java.applet.*;

/*
* <applet code="ParamDemo" width=300 height=80>
* <param name=fontName value=Courier>
* <param name=fontSize value=14>
* <param name=leadin value=2>
* <param name=accountEnabled value=true>
* </applet>
* */

public class ParamDemo extends Applet
{
String fontName;
int fontSize;
float leading;
boolean active;

public void start()
{
String param;
fontName=getParameter("fontName");
if(fontName == null)
{
fontName="No Found";
}
param = getParameter("fontSize");
try
{
if(param != null)
{
fontSize = Integer.parseInt(param);
}
else
{
fontSize = 0;
}
}
catch(NumberFormatException e)
{
fontSize = -1;
}
param = getParameter("leading");
try
{
if(param !=null )
{
leading = Float.valueOf(param).floatValue();
}
else
{
leading = 0;
}

}
catch(NumberFormatException e)
{
leading = -1;
}
param = getParameter("accountEnabled");
if(param != null)
{
active = Boolean.valueOf(param).booleanValue();
}

}
public void paint (Graphics g)
{
g.drawString("Font name:" +fontName, 0,10);
g.drawString("Font size:" +fontSize, 0,26);
g.drawString("Leading:" +leading, 0,42);
g.drawString("Account Active:" +active, 0,58);
}

}

JDK版本为:java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode)
请大哥们为小弟指出错误!谢谢!
