My Jsp file (pieChartLive.jsp)

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>PieChartLive</title>
<p:resources />
</head>
<body>
<h:form id="livePieChartForm">
    <p:pieChart id="votes" value="#{PieChartLiveBean.lunchSalesList}"
        var="lunchSalesBean" live="true" refreshInterval="3000"
        categoryField="#{lunchSalesBean.dishName}"
        dataField="#{lunchSalesBean.salesPercentage}" />
</h:form>
</body>

My web.xml

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> PrimeFaces pieChartLive.jsp

<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>*.jsf</url-pattern>
</servlet-mapping>

<context-param>
    <param-name>primefaces.THEME</param-name>
    <param-value>cupertino</param-value>
</context-param>

My faces-config.xml

<faces-config> 
<managed-bean>
    <managed-bean-name>PieChartLiveBean</managed-bean-name>
    <managed-bean-class>com.sample.primefaces.PieChartLiveBean</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
</managed-bean>

You are mixing jsp and facelets. Your facelet has file suffix .jsp but your web.xml mapping for the Faces Servlet is *.jsf. So the Faces Servlet won't be invoked.

Change the file suffix to .jsf and try again.
