I want to implement JSF page with AJAX. This is the code of the JSF page:
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:head>
<ui:insert name="header">
<ui:include src="header.xhtml"/>
</ui:insert>
</h:head>
<h:body>
<h1><img src="resources/css/images/icon.png" alt="NVIDIA.com" /> Settings Center</h1>
<!-- layer for black background of the buttons -->
<div id="toolbar" style="margin: 0 auto; width:1180px; height:30px; position:relative; background-color:black">
<!-- Include page Navigation -->
<ui:insert name="Navigation">
<ui:include src="Navigation.xhtml"/>
</ui:insert>
</div>
<div id="greenBand" class="ui-state-default ui-corner-allh" style="position:relative; top:35px; left:0px;">
<h:graphicImage alt="Application Settings" style="position:relative; top:-20px; left:9px;" value="resources/images/logo_application_settings.png" />
</div>
<div id="main" style="margin: 0 auto; width:1190px; height:700px; position:absolute; background-color:transparent; top:105px">
<div id="mainpage" style="margin: 0 auto; width:1190px; height:500px; position:absolute; background-color:transparent; top:80px">
<div id="settingsdiv" style="width:350px; height:400px; position:absolute; background-color:r; top:20px; left:1px">
<h:panelGrid columns="2">
<h:panelGroup>User Session Timeout</h:panelGroup>
<h:panelGroup>
<h:selectOneMenu value="#{ApplicationController.settingValue('SessionTTL')}">
<f:selectItem itemValue="one" itemLabel="Option one" />
<f:selectItem itemValue="two" itemLabel="Option two" />
<f:selectItem itemValue="three" itemLabel="Option three" />
<f:selectItem itemValue="custom" itemLabel="Define custom value" />
<f:ajax render="input" />
</h:selectOneMenu>
<h:panelGroup id="input">
<h:inputText value="#{ApplicationController.settingValue('SessionTTL')}" rendered="#{bean.type == 'custom'}" required="true" />
</h:panelGroup>
</h:panelGroup>
<h:panelGroup>Maximum allowed users</h:panelGroup>
<h:panelGroup>#{ApplicationController.settingValue('MaxUsersActive')}</h:panelGroup>
</h:panelGrid>
</div>
<div id="settingslayer" style="width:350px; height:400px; position:absolute; background-color:transparent; top:20px; left:400px">
</div>
<div id="settingspanel" style="width:350px; height:400px; position:absolute; background-color:transparent; top:20px; left:800px">
</div>
</div>
</div>
</h:body>
</html>
When I load the page I get this error:
One or more resources have the target of "head", but no "head" component has been defined within the view.
This is the code of the header:
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets">
<title>Settings Center</title>
<link href="resources/css/helper.css" media="screen" rel="stylesheet" type="text/css" />
<link href="resources/css/dropdown.css" media="screen" rel="stylesheet" type="text/css" />
<link href="resources/css/default.advanced.css" media="screen" rel="stylesheet" type="text/css" />
<!--[if lt IE 7]>
<script type="text/javascript" src="js/jquery/jquery.js"></script>
<script type="text/javascript" src="js/jquery/jquery.dropdown.js"></script>
<![endif]-->
<!-- / END -->
</html>
The Ajax is not working and this error message appears when I load the page. Maybe I'm missing something to add. How I can fix the code?
Best wishes Peter

Well, I guess you need to edit your header.xhtml like this
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<ui:composition>
<title>index</title>
<h:head>
<link rel="stylesheet" href="style.css" type="text/css"
media="screen"/>
<script>....
</script>
</h:head>
Make sure that you use <h:head> - and not <head>.

Try to put <ui:composition> inside <html> and around its content in header.xhtml.
