<object codetype="application/java" codebase="codebase/" classid="java:test.class" width=250 height=50>
alternative text
</object>
An inline Java applet sized 250*50 pixels, showing the words "Hello world!" in big, red italics on a yellow background. If the user agent shows yellow text on a red background instead, it doesn't support the codebase attribute correctly.
User agents which cannot render inline Java applets should display the words "alternative text".
