加了的，不加的话appletviewer不认的，它只认HTML文件。我在firefox可以浏览，就是IE不行，可能是哪设置的问题。

看一下windows中是否装有ms vm如果有，卸掉，然后安装java j2re，装完后会在开始菜单出现java webstar说明安装成功了，再运行试试

ms vm是什么？我在菜单有java web start 啊

java web start 跟 browser 里面用的是哪个 vm 没关系。

IE 里默认的 vm，可以在 Control Panel 里的 Internet Options ->; Advanced 里设置，也可以在 Control Panel 里的 Java Plug-in ->; Browser 里设置。
