关于APPLET出错的问题

[pgyssg]

//: BorderLayout1.java
// Demonstrating the BorderLayout
import java.awt.*;
import java.applet.*;

public class BorderLayout1 extends Applet {
public void init() {
int i = 0;
setLayout(new BorderLayout());
add("North", new Button("Button " + i++));
add("South", new Button("Button " + i++));
add("East", new Button("Button " + i++));
add("West", new Button("Button " + i++));
add("Center", new Button("Button " + i++));
}
}
==================================================
编译Process completed.
执行BorderLayout1.html时,出错不能显示框架.显示出错信息"进行读取时出现I/0异常;
d:\JCreator Pro\MyProjects\ButtonDemo\ButtonDemo\ButtonDemo\classes\BorderLayout1.html(系统找不到指定的文件.)

请教,该如何解决?
