I found the similar question here but it doesn't helping me anymore. However i am facing the same problem. While running my application i get the followine error:
Warning: The page /template/common.xhtml declares namespace http://primefaces.org/ui and uses the tag p:panel , but no TagLibrary associated to namespace.
Below is a snippet of my index.xhtml :
<ui:composition template="/template/common.xhtml"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui">
<ui:define name="profile">
And this is how my common.xhtml file looks (not putting the whole content, just namespaces and 1-2 lines) :
<!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"
xmlns:p="http://primefaces.org/ui">
<h:head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Welcome to my website</title>
<h:outputStylesheet library="css" name="default.css" />
</h:head>
<h:body>
<div id="header" style="margin: auto; width: 80%;">
<p:panel>
As described by BalusC at here, one must define xmlns="http://www.w3.org/1999/xhtml". I am doing the same. i.e. second line of index.xhtml file is doing the same. but still i am getting error.
The PrimeFaces 3.x JAR file is missing in your webapp's /WEB-INF/lib folder. Download and drop it in there. Or, if you're using PrimeFaces 2.x, then you should be using the following XML namespace instead:
xmlns:p="http://primefaces.prime.com.tr/ui"
That other question which you're linking to isn't talking about <p:xxx> tags, but about plain HTML tags like <title>, <div> and so on. It's just the coincidence that in case of that other question the <input> is been placed inside a <p:panel>.
