I'm very new to JSF and I have some problem using JSF template. The code of the template newTemplate.xhtml) looks like this:
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html">
<h:head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link href="./resources/css/default.css" rel="stylesheet" type="text/css" />
<link href="./resources/css/cssLayout.css" rel="stylesheet" type="text/css" />
<title><ui:insert name="title">Default title</ui:insert></title>
</h:head>
<h:body>
<div id="top">
<ui:insert name="top">Top</ui:insert>
</div>
<div>
<div id="left">
<ui:insert name="left">Left</ui:insert>
<h:form>
<h:commandButton id="test" value="Test" action="/jsf/newTemplateClient.xhtml"/>
</h:form>
</div>
<div id="content" class="left_content">
<ui:insert name="content">Content</ui:insert>
</div>
</div>
<div id="bottom">
<ui:insert name="bottom">Bottom</ui:insert>
</div>
</h:body>
</html>
Start page called index1.xhtml looks like this:
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets">
<body>
<ui:composition template="/WEB-INF/newTemplate.xhtml">
<ui:define name="title">
TEST
</ui:define>
</ui:composition>
</body>
</html>
Finally template client page (called newTemplateClient.xhtml):
<ui:composition template="/WEB-INF/newTemplate.xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets">
<ui:define name="content">
Some content in newTemplateClient.xhtml
</ui:define>
</ui:composition>
Here is the behaviour of the application:
Application starts (address bar says localhost:8080/WebTEST/) and the layout and content is displayed properly,
I click on the 'Test' button and the content of newTemplateClient.xhtml is also displayed properly (address changes to: localhost:8080/WebTEST/faces/index1.xhtml),
I click again 'Test' button and the content is displayed but I loose the layout like there is no css style applied (no colors and formatting). Now the address bar says: localhost:8080/WebTEST/faces/jsf/newTemplateClient.xhtml
The template file is located in WEB-INF folder, the newTemplateClient.xhtml is located in jsf folder.
I know it's probably some simple thing but I really ran out of ideas what might be the cause of this problem.
To repeat my comment, the problem is that the relative URL in the CSS links resolves to a different absolute URL after you leave the index page. However, there is a nice JSF tag you can use instead of the raw link to solve your problem: use <h:outputStylesheet library="css" value="default.css"> instead of <link href=...>.

After a year gap i have again started working in JSF and facing problem in the facelets usage Below is the maintemplate.xhtml
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:head>
<title><ui:insert name="title" /></title>
</h:head>
<ui:insert name="header" />
<body>
content
</body>
</html>
Below is the ui:composition of the other xhtml file
enter code here
<?xml version="1.0" encoding="UTF-8" ?>
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.org/ui"
template="/index.xhtml">
<ui:define name="title"><h:outputText value="Please Sign In" /></ui:define>
<ui:define name="header"><h:outputText value="Please Sign In" /></ui:define>
</ui:composition>
the same content works with the ui:include but doesn't work with the ui:defin and ui:insert combination
I was using the tags in the wrong way need to include include tag inside the insert to get the correct template functionality
I am trying to integrate the ICEFaces ACE component library in my project. I've the following view:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<head>
<h:outputStylesheet library="org.icefaces.component.skins"
name="rime.css" />
<f:loadBundle basename="resources.application" var="msg" />
<title>
<h:outputText value="#{msg.templateTitle}" />
</title>
</head>
<body>
<div id="content">
<h:form>
<ace:dataTable var="user" value="#{userBean.users}"
paginator="true" rows="50" selectionMode="multiple">
<ace:column headerText="users">
<ace:row>#{user}</ace:row>
</ace:column>
</ace:dataTable>
</h:form>
</div>
</body>
</html>
Unfortunately apparently there is no JavaScript / CSS loaded, so the components are not displayed properly. Moreover, the server logs this:
ICEfaces configured for view /index.xhtml but h:head and h:body components are required
Is this related?
You need to use JSF <h:head> and <h:body> components instead of plain HTML <head> and <body>. This way JSF and any JSF component library will be able to programmatically auto-include CSS/JS resources in there.
E.g.
<!DOCTYPE html>
<html lang="en"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core">
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
>
<f:loadBundle basename="resources.application" var="msg" />
<h:head>
<title>#{msg.templateTitle}</title>
</h:head>
<h:body>
...
</h:body>
</html>
Note that this way you also don't need that <h:outputStylesheet> anymore.
See also:
One or more resources has the target of 'head' but not 'head' component has been defined within the view
Unrelated to the concrete problem, you'd better declare resources.application as <resource-bundle> in faces-config.xml, so that you don't need to repeat it over all views. Also note that you don't necessarily need <h:outputText> over all place. The <head> and all of above also indicates that you're learning JSF based on a JSF 1.x targeted tutorial instead of a 2.x targeted one. Make sure that you're using the right resources to learn.
I'm working on a web solution using myfaces and primefaces. We have several pages in our solution, and some of the get this mystical error myfaces not defined because there is a javascript file that is not included on the page, namely the jsf.js file:
<script type="text/javascript" src="/driwkraft-hig/javax.faces.resource/jsf.js.xhtml?ln=javax.faces&stage=Development">
The error occurs when clicking on certain commandlinks on the page, where the generated javascript has been set to onClick="myfaces.oam.submitForm...
Now, I understand that this is something that the JSF framework adds to the page based on some mystical criteria which I fail to understand. There are pages that appear to be equal with regards to what elements are used, and it succeeds on one and fails on the other.
I have tried to create a test-file where I copied content of one of the failing pages and then removed parts until it would work to figure out what was the source of the problem, but this did not give me anything. My next hunch is that it might be some configuration-error somewhere. But I am completely and utterly blank as to where to start.
I understand I should probable add some code or xml in to this question, but I cannot post the entire solution so I think it is best to do so upon request. Would the web.xml be useful? How about the faces-config.xml?
Any guidance and thoughts are much appreciated!
Edit - adding template
<?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">

It's auto-included if there's a <h:head> in the template which automatically renders CSS/JS dependencies from UIViewRoot#getComponentResources() which are added via #ResourceDependency annotation on the JSF component.
Those problem symptoms suggests that there's no <h:head> in the template, but a plain <head>. Therefore JSF is unable to auto-include CSS/JS resource dependencies which in turn causes this JS error.
To fix this problem, just make sure that there's a <h:head> instead of <head> in the template.
<!DOCTYPE html>
<html lang="en"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:head> <!-- Look here. -->
<title>Blah</title>
</h:head>
<h:body>
<h1>Blah</h1>
<p>Blah blah.</p>
</h:body>
</html>
So I have:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.org/ui">
<h:body>
<ui:composition template="template.xhtml">
<ui:define name="content">
<h:outputText value="Test!!!" />
</ui:define>
</ui:composition>
</h:body>
</html>
as my main page on my website and on template.xhtml:
<div id="content">
<h:panelGroup layout="block" styleClass="centercss">
<ui:insert name="content" />
</h:panelGroup>
</div>
...in the middle of the footer and the header views.
Now if I try to change the template="template.xhtml" to template.jsf it does not appear anywhere... the way it is right now I get my 'content' page perfectly in the middle of header and footer on the eclipse preview, but on the browser there's no content at all.
Im using primefaces3.1.1 and I have javax.faces-2.1.14 + jsf-api and jsf-impl, so I think its primefaces 3 and JSF 2.
What is the problem here ?
I think you are using facelets (templating) in a wrong way. You should'nt have html and body tags on your main page. The page that will use the template must be defined in a <ui:composition> tag, and the template shall define the page as a whole (html, body, head tags, etc).
Example:
index.html
<?xml version="1.0" encoding="UTF-8"?>
<ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:p="http://primefaces.org/ui"
template="template.xhtml">
<ui:define name="content">
<h:outputText value="Test!!!" />
</ui:define>
</ui:composition>
template.xhtml
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:body>
<div id="content">
<h:panelGroup layout="block" style="background-color: red;">
<ui:insert name="content" />
</h:panelGroup>
</div>
</h:body>
</html>
I have a simple JSF application with 2 .xhtml files. When I run the application, the 1st page displayed is welcome.xhtml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<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>Final Project</title>
</h:head>
<h:body bgcolor="white">
<div align="center" style="border:5px outset blue;">Welcome to the Product Inventory Application</div>
<br></br>
<br></br>
<h:commandButton value="View All Products" action="allProducts"/>
</h:body>
It displays fine, but when I press the View All Products button, I expect it to display the allProducts.xhtml facelet. But when I click the button, nothing happens at all, no exception or anything. The allProducts.xhtml page is just:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<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>All Products</title>
</h:head>
<h:body bgcolor="white">
<h3>Test</h3>
</h:body>
</html>
The problem is that an UICommand (<h:commandButton>, <h:commandLink> and similars) must be inside a form i.e. <h:form>. Change your welcome.xhtml page to:
<!DOCTYPE html>
<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>Final Project</title>
</h:head>
<h:body bgcolor="white">
<div align="center" style="border:5px outset blue;">Welcome to the Product Inventory Application</div>
<br></br>
<br></br>
<h:form>
<h:commandButton value="View All Products" action="allProducts"/>
</h:form>
</h:body>
More info:
h:commandLink / h:commandButton is not being invoked, reason 1. IMO, I suggest you to mark this question as a favorite if you're going to work a lot with JSF :).
I don't know the precise detail by heart, but here is the general idea. The action attribute of the button on the welcome page is referring to an 'allProducts' method of the backing bean. That method would have to return the string 'allProducts.xhtml' in order to have JSF present the products page.
So you have to introduce a backing bean for the welcome page and endow that class with a method 'allProducts'.
