JSF Probleme mit Data Table

Posted on 05:28 by verona
Hallo liebes Forum ich habe eine Frage warum bei mir das nicht funktioniert:



Also ich habe eine einfache Data Table erzeugt.



<?xml version='1.0' encoding='UTF-8' ?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://ift.tt/nuHeHq;

<html xmlns="http://ift.tt/rO9lWA;

xmlns:h="http://ift.tt/1x2KsZ1;

xmlns:f="http://ift.tt/1AmiKIo;

xmlns:p="http://ift.tt/1z85qfZ;

<h:head>

<title>Facelet Title</title>

</h:head>

<h:body>

<h:form id="form">



<p:dataTable var="p" value="#{Bean.pers}">

<p:column headerText="Vorname">

<h:outputText value="#{p.getvName}" />

</p:column>



<p:column headerText="Nachname">

<h:outputText value="#{p.getnName}" />

</p:column>



<p:column headerText="Alter">

<h:outputText value="#{p.alter}" />

</p:column>





</p:dataTable>

</h:form>

</h:body>

</html>

Die Fehlermeldung die Ausgegeben wird ist :
