Running Java Applets To use an applet with your web page, you add tags to the web page and place the class file (the applet file) on your web site, usually in the same directory as your web pages. Originally, Java applets were enclosed in
and tags, but more recent versions of HTML require applets to appear within and tags.
tag, the CODETYPE attribute is optional, but helps browsers that are not Java-enabled to avoid downloading the applet. The CLASSID attribute is required because it specifies the applet filename (sitemap.class in this example). The WIDTH and HEIGHT attributes are optional, but are usually included to give the dimensions (in pixels) of the area of the page where the applet is allowed to write. tag can also include the following optional attributes: The URL where the applet file resides, if it is not in Horizontal alignment; for example, center ALT Alternate text that appears if the browser can't process the applet tags or you may need many. In the preceding example, the web page developer has set three parameters named bgcolor (background color), font, and url to various values. You must read the applet's documentation to know how to set its parameters.
