fala pessoal, estou com uma dúvida que eu não consigo resolver, peguei uma apostila de um curso na internet para estudar JSF, eu fui seguindo passo a passo, mas a tela menu, que tem dois botões, reclama quando eu clico no botão para consultar os objetos.
vou colocar o erro e algumas partes do código, se alguem puder me ajudar fico muito grato.
página menu.jsp
<f:view>
<h:form id=“frm”>
<h:outputText value=“Sistema Financeiro” />
<h:commandLink action="#{cadastroContaBean.inicializar}" >
<h:outputText value="Cadastro de contas" />
</h:commandLink> <br/>
<h:commandLink action="consultaConta" actionListener="#{consultaContaBean.consultar}" >
<h:outputText value="Consulta de contas" />
</h:commandLink> <br/>
</h:form>
</f:view>
ao invocar o actionListenter no método consultar do bean, ele deveria me retornar uma tela com uma lista, mas ele mostra esse erro aqui dizendo como se o método no managedbean não existisse.

aqui está a parte do código do meu managedbean
public class ConsultaContaBean {
private Conta contaExclusao;
private List<Conta> contas = new ArrayList<Conta>();
public void consultar(ActionEvent event) {
this.contas = new ContaService().listarTodas();
}
eu ainda tenho bastante dificuldade para manipular botões que tenham atributos do tipo listener, eu acho que pode ter haver com o fato de não ser apenas action.
Aguardo respostas e valew…
dele não ser simplesmente action
