Can't use PrimeFaces with Maven - eclipse

I added PrimeFaces to my pom.xml dependencies and in my project there is the jar file primefaces-4.0.jar.
Then I created a simple xhtml file with the following content:
<!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:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui">
<head>
</head>
<body>
<p:spinner />
</body>
</html>
After deploying and calling the jsf file in my browser, I just get an simple input field, that has nothing to do with PrimeFaces. There are no error messages in my Eclipse console.
Can somebody help me? What could be the problem?


Try replacing <body> with <h:body>. Also, <h:head> should be used instead of <head>.
Refer to PrimeFaces Getting Started page.


For maven configure:
<dependency>
<groupId>org.primefaces</groupId>
<artifactId>primefaces</artifactId>
<version>5.1</version>
</dependency>
web.xml configure
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>


i got the same error, only when i cutted off the dependency by maven and inserted the jar i could see the correct rendering of the primefaces tags.

Add a index.jsp under the directory of WebContent.below is the page code in it.
<%# page language="java" contentType="text/html; charset=ISO-8859-1"

And after I published it to the build-in Tomcat server run-time in the Eclipse. There is no error when the server is started.
But I got a empty page for the url http://localhost:8080/MyFirstWeb/index.jsp, Why? thanks.

</welcome-file-list>

Well I used your exact code in Eclipse and it is working perfectly fine. can you post what the error is.?
And check if your web.xml has this
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

http 404 error report tomcat eclipse

I'm really new to web app and this is my first time using tomcat. I keep getting this message when try to run index.jsp.
I'm using eclipse indigo, with tomcat 6.0 (Tomcat v6.0 Server at localhost already started and synchronized). I've already copied ROOT folder to wtpwebapp, checked <Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" /> in server.xml file, but nothing seems work.
Here's the server configuration:
I just started index.jsp with this:

</welcome-file-list>
</web-app>
I wonder what's wrong...Thanks in advance.

First of all i want to know which frame work r u using. If u r working on struts 2 just try replacing ur code in web.xml with this code...
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

The following worked for me: Try dragging index.jsp to the WebContent directory. Then, right click index.jsp and click "Run on server".

Simple primefaces application not working

I am trying to build simple JSF application using primefaces but somehow primefaces components are not getting rendered properly. I dont understand what is going wrong.
I am trying to display following Facelet file :
<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.prime.com.tr/ui">
<h:head>
<link type="text/css"
rel="stylesheet"
href="/Themes/primefaces-dot-luv/theme.css" />
</h:head>
<h:body>
<p:spinner value="100" style="height: 10px" />
<br/>
<p:button value="Navigate"></p:button>
</h:body>
</html>
I am using eclipse to run the app on tomcat server. When I run the application and view the page source in browser(firefox) I get following source :
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:p="http://primefaces.prime.com.tr/ui">
<head>
<link type="text/css" rel="stylesheet" href="Themes/primefaces-dot-luv/theme.css" />
</head>
<body>
<p:spinner value="100" style="height: 10px"></p:spinner>
<br />
<p:button value="Navigate"></p:button>
</body>
</html>
I think PrimeFaces components are not getting rendered properly. Other JSF tags like <h:head> and <h:body> are converted correctly to <head> and <body> elements respectively. Only tags starting with <p:> are not converted.
Following is my project structure :
My web.xml looks like this:

I am using eclipse , tomcat server. JSF 2 and primefaces 3 library.
Hi, After some close inspection of entire project I found out that
primefaces jar dowlonaded from site did not had any classes. Jar
itself was corrupt. I downloaded same jar thrice then also jar was
getting corrupt. So I downloaded zip file containing source and
binaries and my application started working.

Try changing your web.xml servlet mapping:
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
The way to tell if the Facelets Servlet is processing your xhtml is to look at what the browser receives. If it looks like your xhtml file then you have something mis-configured.

Your need change
xmlns:p="http://primefaces.prime.com.tr/ui"
to
xmlns:p="http://primefaces.org/ui"

You should change your namespace into xmlns:p="http://primefaces.org/ui"
and implement button like this way
<p:commandButton value="Home" process="#this" action="actionMethod()" immediate="true" rendered="true or renderingMethod()" />
