note The full stack trace of the root cause is available in the Apache Tomcat/6.0.16 logs.

ja conferi e esta tudo certo com a minha classe "TesteJSF" segue a mesma:

package teste;

public class TesteJSF {
	private String version;
	private String nome;
	
	public TesteJSF(){
		setVersion("1.2");
		setNome("Java Server Faces");
	}

	public void setVersion(String version) {
		this.version = version;
	}

	public String getVersion() {
		return version;
	}

	public void setNome(String nome) {
		this.nome = nome;
	}

	public String getNome() {
		return nome;
	}
}

segue classe TesteJSFBean:

package teste;

import java.util.ArrayList;
import java.util.List;

import javax.faces.model.DataModel;
import javax.faces.model.ListDataModel;

public class TesteJSfBean {
	private List<TesteJSF> todos;
	
	public TesteJSfBean(){
		todos = new ArrayList<TesteJSF>();
		todos.add(new TesteJSF());
		todos.add(new TesteJSF());
		todos.add(new TesteJSF());
	}

	public DataModel getTodos(){
		DataModel model = new ListDataModel(todos);
		return model;
	}
}

segue arquivo .jsp:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Teste JSF</title>
</head>
<body>
	<f:view>
		<h:form>
			<h:dataTable id="items" value="#{testeView.todos}"
				var="item" border="1"
				cellpadding="2" cellspacing="0">

				<f:facet name="header">
					<h:outputText value="Teste JSF" />
				</f:facet>
				
				<h:column>
					<f:facet name="header">
						<h:outputText value="Versão" />
					</f:facet>
					<h:outputText value="#{item.version}" />
				</h:column>	
				
				<h:column>
					<f:facet name="header">
						<h:outputText value="Nome" />
					</f:facet>
					<h:outputText value="#{item.nome}" />
				</h:column>	
				
			</h:dataTable>		
		</h:form>
	</f:view>
</body>
</html>

segue faces-config.xml :

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

<faces-config
    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-facesconfig_1_2.xsd"
    version="1.2">

	 <managed-bean>
	 	<managed-bean-name>testeView</managed-bean-name>
	 	<managed-bean-class>
	 	teste.TesteJSfBean</managed-bean-class>
	 	<managed-bean-scope>session</managed-bean-scope>
	 </managed-bean>

</faces-config>

se eu retirar a propriedade para exibir tipo edeixar so:

<h:outputText value="#{item}" />

isso no lugar de

<h:outputText value="#{item.nome}" />

ele funciona mas gera o seguinte resultado: anexo1

esta muito estranho... ¬¬

sera q alguma alma generosa poderia me ajudar... e ja enfrentei problemas com jsf 1.2 e tomcat 6 mas era a respeito do componente DataTable... dai resolvi utilizar o jsf 1.1 e tomcat 5.5 =(

mas esse aqui ta dificil ^^

blz ate +
