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>.

  • Why is that necessary for some JAR to be in lib directory while some can be added as User Library, when using Eclipse?? – Azfar Niaz Jun 13 '13 at 12:52

    @Azfar: Only if you didn't properly configure the user library to automatically end up in `/WEB-INF/lib` of deployment. For future questions, please press `Ask Question` button in right top and don't abuse comments of a different question for that. – BalusC Jun 13 '13 at 12:56

Just dowmload the jar from Java2s primefaces jar downloads and then add the jar to libraries folder in your project

    Bad, bad, bad suggestion in multiple ways... First it refers to a prehistoric version of PrimeFaces, secondly, one should either use the PrimeFaces repository or maven-central... as a **_TRUSTED SOURCE_** – Kukeltje Sep 07 '18 at 10:52
