A XHTML Page Is A Valid ZUML Page

The Web page illustrated below is a simple but typical example.

<html>
<head>
    <title>ZHTMLDemo</title>    
</head>
<body>
        <h1>ZHTMLDemo</h1>        
        <ulid="ul">        
                <li>Thefirstitem.</li>                
                <li>Theseconditem.</li>                
    </ul>    
                <inputtype="button"value="AddItem""/>                
    <br/>    
                <inputid="inp0"type="text"/>+                
                <inputid="inp1"type="text"/>=                
        <textid="out"/>        
</body>
</html>

By naming it with the zhtml extension^[51], it will be interpreted as a ZUML page by ZK loader. Then, instances of org.zkoss.zhtml.Html, org.zkoss.zhtml.Head and others are created accordingly. In other words, we created a tree of XHTML components at the server. Then, ZK renders them into a regular XHTML page and sends it back to the browser, like what we did for any ZUML pages.

^[51]If you want every HTML pages to be ZUML pages, you could map the .html extension to DHtmlLayoutServlet. Refer to Appendix A in the Developer's Reference for details.
