信心大减,一个Applet的HelloWorld问题...救救我吧.(100分)

iamfish · 2004-02-05

写过一点点Java Application,也没怎么遇过难题.这两天想写点Applet,即遇到这样的问题,已经两天了.
写了一个HelloWord的小Applet.编译成功,用AppletViewer查看也成功,但在网页中就是"Load: Class GetURL no found."
查看IE的缓存,有GetURL.class文件.
JDK 是:j2sdk1.4.1_01
我用JCreator2.5编译.也有试过用Javac编译,都不行.运行Java Application可以.查看网上其它的Applet也可以.

GetULR.java

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

public class GetURL extends Applet {

public void init() {
}
public void paint(Graphics g) {
g.drawString("Welcome to Java!!", 50, 60 );
}
}

<body>
<applet cabbase="." code="GetURL.class" height="300" width="300" alt="Applet" mayscript="A" name="AP">test</applet>
</body>
</html>

下载

大家帮想一下是什么问题吧.是不是JSDK的问题?

你的文件名搞错了。
GetURL.class---->GetULR.class

dannyfan · 2004-02-05

可以运行呀。
你把http://127.0.0.1:20013/java 去掉，HTM 和 CLASS 文件放在同一个目录，试一试

我搞定了,主要是J2SDK1.4的HTML的写法,不能用Applet标记.
