Problemas com JSTL (resolvido)

Estou usando Eclipse 3.3.1.1 e Tomcat 6.1 e fiz um jsp que deveria mostrar dados de uma tabela e parece que os comandos jstl não estão sendo interpretados.
O fonte do jsp:

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

<html>

<jsp:useBean id="db" class="dados.ArquivosDao" />

<!-- for para interagir com a lista retornada -->
 
<c:forEach var="aluno" items="${db.lista}">
 
 <li>
     <c:set var="nome" value="${aluno.nome}"/>
  nome: <c:out value="${nome}"/>,
  id ${aluno.id},
  Nascto ${aluno.dtNascto}
 </li>
 
</c:forEach>
     
<%
   db.disconnect();
%>

</html>

O resultado:

nome: ${nome}, id ${aluno.id}, Nascto ${aluno.dtNascto}

Criei outro projeto e levei esse jsp para lá e funcionou. Mas por que ? Por favor, quem puder me ajude, porque está ficando difícil acreditar que programar em Java seja produtivo.

Obrigado.

Oi,

Faz assim

<c:forEach var="aluno" items="${db.lista}" varStatus="id"> <li>${id.count} - ${aluno.nome} : ${aluno.dtNascto}</li> </c:forEach>

Tem outra coisa também, não faça db.disconnect() na sua jsp, crie uma fábrica de conexões para retornar a conexão para o seu dao, essa fábrica que deve encerrar a conexão, normalmente isso é feito em um finally

Abs

Infelizmente não funcionou. Provavelmente o erro deve estar em alguma configuração: web.xml; struts-config.xml ou outros.

Obrigado

Quem puder ajudar, eu agradeço antecipadamente.

Bem consegui fazer funcionar o jsp mais não descobri o erro. Tudo começou com testes com o Struts que tinha uma saída em jsp, que apresentou o erro do tópico. Tentei isolar o problema e nada de funcionar.
O que eu fiz:
** criei um novo projeto no Eclipse com o plugin do Tomcat;
** acrescentei o jsp mencionado acima e executei-o com sucesso
** acrescentei a estrutura do Struts com o plugin SrutsIde
** executei novamente o jsp e funcionou
** acrescentei os fontes ligados ao Struts, alterei web.xml e struts-config.xml de acordo com o projeto com problemas e …funcionou.

Que maravilha !!! Funciona, mas fica no campo do “esoterismo” a razão da execução bem sucedida desse novo projeto.
