Answer 1

test.html
应该和test包
放在一起，也就是同一个文件夹下

Answer 2

我是放在一起的啊
test.html 和 我用的 applet程序 都在同一目录下啊

Answer 3

把APPLET文件的代码贴出来看看

Answer 4

是不是要设置环境啊path已经设置了，要不然我也没办法运行appletviewer 和 编译applet程序

Answer 6

html文件xxx.html
<html>
<applet code=test.no2 width=300 height=300></applet>
</html>你的no2.java编译出来一个包test，也就是test文件夹xxx.html和test文件夹放在同一个文件夹下，就ok了在这个目录下，appletviewer xxx.html
