Just learned Applets, there have been such embarrassment, Applet compiles, and the corresponding code has also joined HTML. When it is turned on in IE, there is only one gray area, and the status bar shows the error such as Class Not Found. information. View Applet with the AppletViewer program comes with Java SDK, but it can be displayed normally. I found a few articles on the Internet. The problem finally solved. I immediately wanted to write these steps. So yourself after I forgot, and I have to go everywhere.
First, open the IE Internet option, and select the Java console in advanced
After that, you need to download the corresponding Plugin:
1) Open the web page http://java.sun.com/products/plugin/
2) Click on the link in Java Plug-in DemonStration Applets
3) The last chooses a DemonStration applet such as 3D Chemical Models
4) After opening the page, start automatically downloading the plugin and install
5) Restart after completion
After this step, open the HTML file again and find that the applet is displayed normally.
