I read somewhere that the Facelet Tag Libraries URI's changed from http://java.sun.com/jsf/* to http://xmlns.jcp.org/jsf/*, so that means the new namespaces applies only for the new specification(JSF 2.2) or they can or should be used in older versions like 2.0, 2.1 or 1.x?
for example:
Library Old URI New URI
Composite Components http://java.sun.com/jsf/composite http://xmlns.jcp.org/jsf/composite
Faces Core http://java.sun.com/jsf/core http://xmlns.jcp.org/jsf/core
HTML_BASIC http://java.sun.com/jsf/html http://xmlns.jcp.org/jsf/html
JSTL Core http://java.sun.com/jsp/jstl/core http://xmlns.jcp.org/jsp/jstl/core
Facelets Templating http://java.sun.com/jsf/facelets http://xmlns.jcp.org/jsf/facelets
EDIT
To make the question more understandable nothing like a snippet of code:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:h="http://xmlns.jcp.org/jsf/html">
<h:head>
<title>test</title>
<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=UTF-8" />
<link rel="stylesheet" type="text/css" title="Style" href="theme/stylesheet.css" />
</h:head>
<h:body>
<h:form id="form1" styleClass="form">
<h:inputText id="text1" styleClass="inputText"></h:inputText>
</h:form>
</h:body>
</html>
The previous code would be valid for JSF 2.0? notice the taglibs:
xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:h="http://xmlns.jcp.org/jsf/html"
Thanks.
From what I've seen here : http://www.oracle.com/webfolder/technetwork/jsc/xml/ns/index.html, the canonical names for the large majority of taglibs stays http://java.sun.com/
However, as stated, you can use the new URIs since they created an alias.

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.

When I run above code, I get:

<c:redirect> tag is not available in the Facets 2.0 . For list of available or supported tags . see Tag Library Documentation Generator. You can make use of jsf page navigation to redirect.

I am trying to set a variable with viewparam but I can't seem to get the code to compile in eclipse. It seems like it's not finding the tags.

Your major mistake is that JSP is a deprecated view technology and is clearly a wrong tool for new projects. It has been succeeded by facelets, which is the default view technology for JSF 2.0+ projects.
Some tags, namely the ones used by you like <f:metadata> and <f:viewParam> are not available in JSPs (see sections 10.4.1.3 and 2.5.5 of JSF 2.2 specification (JSR-344) respectively).
The solution is straightforward: switch to facelets as the view technology.
It is also requested to switch to using the new namespaces that have been proposed since JSF 2.2, namely http://java.sun.com should now become http://xmlns.jcp.org (see Preface, page 8 of JSF 2.2 specification (JSR-344)), though both namespaces will work. Also see BalusC's comment to this answer and BalusC's answer to a similar question.
This is my first application with eclipse and jsf and i having some problems.
Here is my project structure:
eclipse project structure
I have downloaded and used JSF 2.1 (Mojarra 2.1.6-FCS) jar file and there is only a single jar file in that and i have used that jar file as a user library.
Now the problem i am facing is that when i use h:head in my index.xhtml file it shows that h:head is an unkown tag.Of course i am using anugular brackets. besides h:head , i am not able to type that in here.
here is my index.xhtml file:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>Insert title here</title>
</h:head>
<body>
</body>
</html>
What is wrong here? IS there only one jar file file to be included?
also there are some white packages marks in the jar file i included...here they are:
while package in jar
what does it mean?
The problem is that you haven't defined the h prefix anywhere in your file. If you follow a JSF 2 tutorial, you will note this in the <html> tag definition (this one is taken from StackOverflow JSF wiki):
<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">
Where
h for JSF HTML tags like <h:head>, <h:body>, <h:inputText>, etc.
f is the prefix for JSF core like <f:view>, <f:selectItems>, <f:ajax>, etc.
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!

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.
