Referência Circular - Spring

Olá a todos.

    Estou com o seguinte problema:
            A aplicação utiliza Hibernate + Spring + Struts, e para as telas utiliza um framework javascript ExtJS.
            Possuo duas entidades: Funcionario e HoraTrabalhada, essas entidades se relacionam, abaixo o código:

            Funcionario.java
           [code]

package com.lpinformatica.sistemaponto.model.schema.administracao;

public class Funcionario implements Serializable {

@OneToOne(fetch = FetchType.LAZY, cascade = CascadeType.PERSIST, optional = true)

   // Relacionamento em questão, aparentemente onde o erro está relacionado....

   [/code]


           HoraTrabalhada.java

@Id @GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "IDHORATRABALHADA")

   //Método em questão, onde aparentemente o erro está relacionado
@ManyToOne(cascade = CascadeType.PERSIST, fetch = FetchType.LAZY, optional = false)

private Funcionario funcionario;
    //-------------------------------------------------------------------------------------------

@Column(name = "HORAENTRADA", nullable = false)
@Type(type = "time")
private Date horaEntrada;

@Column(name = "HORASAIDAINTERVALO", nullable = true)
@Type(type = "time")
private Date horaSaidaIntervalo;

@Column(name = "HORAENTRADAINTERVALO", nullable = true)
@Type(type = "time")

@Column(name = "DATAPONTO", nullable = false)
@Type(type = "date")
private Date dataPonto;
    
    //Abaixo estão os contrutores e métodos
   [/code]


   A aplicação inicia normalmente, mas quando tento cadastrar um funcionário utilizando o hibernate ocorre uma excessao:

    Conforme a exception ocorre um erro ao tentar criar o bean "funcionario". Já fiz diversas busca na web sobre esta questão, mas não consegui encontrar nada que resolvesse meu problema.
    Agradeço à todos pela ajuda dos colegas.

Abraço.

Você está usando o spring, para criar beans dos seus pojos ?

Tipo:

<bean class="com.lpinformatica.sistemaponto.model.schema.administracao.Funcionario">
</bean>

Se estiver, posta o código xml ai.

Acabei resolvendo aqui…

       Se tratava de uma referência circular onde um bean estava chamando o outro...

Poste o código da sua solução (como era antes e como ficou depois).
