Pessoal,

O problema não era com o vraptor, faltava adicionar as duas .jar na pasta WEB-INF\LIB\ ( jstl.jar e statndard.jar)

Obrigado.

#3

outro detalhe importante e que esta nos exemplos do VRaptor é que a URL, variaveis retornadas diretamente pelo vraptor ficam em minusculo.

Exemplo:

minha classe controller:

@Resource
public class ServicesController {

	private final Result result;
	private ServicesDAO dao;
	
	public ServicesController(Result result, ServicesDAO dao) {
		this.result = result;
		this.dao = dao;
	}
	
	public List<Services> list() {
		return dao.listAll();
    }
}

Meu JSP Errado:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<ul>
<c:forEach items="${ServicesList}" var="services">
    <li> ${services.description}</li>
</c:forEach>
</ul>

O VRaptor retorna o objeto da lista com nome minusculo.
Para funcionar bastou corrigir o nome da lista de ServicesList para servicesList:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<ul>
<c:forEach items="${servicesList}" var="services">
    <li> ${services.description}</li>
</c:forEach>
</ul>
