Estou desenvolvendo uma aplicação simples com struts e estou com alguns problemas.

Queria que quando realizar o validate no ActionForm retornasse o erro para a jsp que chamou e apresentando o erro. Só que nao estou conseguindo fazer.

Uma outra coisa, nao estou conseguindo exibir nenhuma chave no jsp (Exception).

Segue os codigos.

CadastrarCliente JSP 
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>

<html:html>
	<head>
		<title>bakakba</title>
		<html:base/>
	</head>
<body>
	
<html:form action="cadastrarCliente.do">
	Nome:<html:text property="nome" size="25" /><html:errors property="nome"/><br>
	CPF:<html:text property="cpf" size="25"/><html:errors property="cpf"/><br>
	<html:submit>Enviar</html:submit>
     <html:reset>Reset</html:reset>
     <html:errors property="errnome" />
	<html:errors property="errcpf" /> 
	<bean:message key="error.nome"/>
</html:form>

</body>

</html:html>
CadastrarCliente ActionForm 
package struts;

import javax.servlet.http.HttpServletRequest;

public class CadastrarClienteForm extends ActionForm {
	
		private String nome;
		private String cpf;
		
		public ActionErrors validate(ActionMapping map, HttpServletRequest req) {
			ActionErrors erros = new ActionErrors();
			
			if ((cpf == null) || ((cpf.length() < 1)) ){
				erros.add("errcpf", new ActionMessage("error.cpf"));
				
			}
			if ((nome == null) || (nome.length() < 1)) {
				erros.add("errnome", new ActionMessage("error.nome"));
				
			}

			return erros;
		}
		
		public void reset(ActionMapping map, HttpServletRequest req) {
			nome = "";
			cpf = "";
		}

		public String getCpf() {
			return cpf;
		}

		public void setCpf(String cpf) {
			this.cpf = cpf;
		}

		public String getNome() {
			return nome;

		public void setNome(String nome) {

}
CadastrarCliente Action

		CadastrarClienteForm formcliente = (CadastrarClienteForm)form;
		
		bean.setCpf(formcliente.getCpf());
		bean.setNome(formcliente.getNome());
		
		ClienteDAO dao = new ClienteDAO();
		if (dao.save(bean)) {
