Boa tarde.

Estou fazendo meu primeiro teste de jsf2 com primefaces e estou tendo o seguinte Exception:

WARNING: JSF1063: AVISO! Definindo valor de atributo não serializável em HttpSession (chave: extratoMB, classe do valor: br.com.voip.mbeans.ExtratoMB).

Isto ocorre na action que submete duas datas no codigo abaixo:

        <h:form prependId="false">
            <h1>Extrato</h1>
            Cliente: #{loginMB.ccCard.firstname} #{loginMB.ccCard.lastname}
            <br/>
            Data Inicial: <p:calendar value="#{extratoMB.dtInicio}" size="10" showOn="button" />
            Data Final: <p:calendar value="#{extratoMB.dtFim}" size="10" showOn="button"/>
            <h:commandButton value="Consultar" action="#{extratoMB.consultar}" />
        </h:form>
@ManagedBean
@SessionScoped
public class ExtratoMB {

    @PersistenceContext
    EntityManager em;
    @Resource
    private UserTransaction utx;
    private Date dtInicio;
    private Date dtFim;
   
    /** Creates a new instance of LoginMB */
    public ExtratoMB() {
    }

    public String consultar() {
        System.out.println(dtInicio);
        System.out.println(dtFim);
        return "extrato";
    }

    /**
     * @return the dtInicio
     */
    public Date getDtInicio() {
        return dtInicio;
    }

    /**
     * @param dtInicio the dtInicio to set
     */
    public void setDtInicio(Date dtInicio) {
        this.dtInicio = dtInicio;
    }

    /**
     * @return the dtFim
     */
    public Date getDtFim() {
        return dtFim;
    }

    /**
     * @param dtFim the dtFim to set
     */
    public void setDtFim(Date dtFim) {
        this.dtFim = dtFim;
    }

    
}

Para usar o primefaces tem que fazer alguma configuração extra?

Tente colocar:

public class ExtratoMB implements java.io.Serializable {
#3

[quote=Talius]Tente colocar:

public class ExtratoMB implements java.io.Serializable {

Pq?

A Seriaização é o mecanismo que a linguagem Java tem que permite armazenar os objetos em disco.

As ManagedBeans devem implementar Serializable, pois dão a possibilidade do servidor persistir seus dados no disco para poder sobreviver a sobrecargas.
