Using the applet Tag

> You use the `applet` tag to deploy applets to a multi-browser environment.

> For complete details on the `applet` tag, read the W3 HTML specification.

> > Note: The HTML specification states that the `applet` tag is deprecated, and that you should use the `object` tag instead. However, the specification is vague about how browsers should implement the `object` tag to support Java applets, and browser support is currently inconsistent. It is therefore recommended that you continue to use the `applet` tag as a consistent way to deploy Java applets across browsers on all platforms.

> Following is an example of the applet tag:

> >         <applet code=Applet1.class width="200" height="200">
> >         Your browser does not support the applet tag.
> >         </applet>

> For both Internet Explorer and the Mozilla family of browsers, if Java Plug-in is installed (version 1.3.1_01a or later) then the latest installed version of Java Plug-in is invoked to run the applet.

> > Note: You cannot use the `applet` tag to automatically download a JRE if one is not installed locally.
