JSF tags not being rendered as HTML

mmutilva picture mmutilva · Feb 5, 2010 · Viewed 20.9k times · Source

I'm following the Java EE firstcup tutorial using Netbeans and Glassfish.

When I execute the JSF web tier I've been instructed to code, the browser gets the same JSF markup coded in the .xhtml file, and the tags are not rendered as HTML tags. I know this by using the view source code in my browser.

For example, for this code:

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:h="http://java.sun.com/jsf/html">
    <h:head>
        <title>Page title here</title>
    </h:head>
    <h:body>
        <h2>
            <h:outputText value="#{bundle.WelcomeMessage}" />
        </h2>
    </h:body>
</html>

The browser should get something like:

<html ...>
    <head>
        <title>Page title here</title>
    </head>
    <body>
        <h2>
            the welcome message goes here
        </h2>
    </body>
</html>

Right?

Well, my browser is getting jsf code (the first piece of code above) and not the html code (the second piece of code above).

It seems to be a configuration problem in netbeans or glassfish but don't know what. Any ideas?

If JSF tags are not been parsed, then it simply means that the request has not been passed through the FacesServlet. That servlet is the one responsible for all that JSF stuff. You need to verify if the request URL used matches the url-pattern of the FacesServlet. Note that it is case sensitive.

This may however also happen if you opened the file directly in the builtin browser of the IDE. You shouldn't do that. You need to specify the right URL yourself in the address bar of either the builtin browser or an external browser (e.g. MSIE/Firefox).

Update: one more thing, did you declare the JSF HTML taglib in <html xmlns> attribtue? You omitted that in your code snippet.

It should look like

<html 
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html">
