javax.ejb.EJBException：事务已中止标记为回滚的事务

Question

我正在使用EJB开发JavaEE应用程序。

我的两个实体如下：

@Entity
public class Utente implements Serializable {
/**
 * 
 */
private static final long serialVersionUID = 1L;

@Id
@GeneratedValue
private int cod_utente; //BI
private String nome_utente;
private String morada_utente;
@Temporal(TemporalType.DATE)
private GregorianCalendar dnasc_utente;
private int tel_utente;
private ArrayList<GregorianCalendar> agenda;
@OneToMany
@Column(nullable=true)
private ArrayList<Prescricao> lista_presc;

和

@Entity
public class FichaClinica implements Serializable{
/**
 * 
 */
private static final long serialVersionUID = 1L;
/**
 * 
 */
@Id
@GeneratedValue
private int cod_ficha;
@OneToOne
private Utente utente;
@OneToMany
@Column(nullable=true)
private ArrayList <AtoEnfermagem> lista_atos_enf;
@OneToMany
@Column(nullable=true)
private ArrayList <AtoMedico> lista_atos_medicos;
@OneToMany
@Column(nullable=true)
private ArrayList<Consulta> lista_consultas;

当我尝试使用以下方法创建实体 Utente 和 FichaClinica 时：

@Override
public String cria_utente(String nome_utente, String morada_utente,GregorianCalendar dnasc_utente, int tel_utente) {
    Utente u=new Utente(nome_utente,morada_utente,dnasc_utente,tel_utente);
    em.persist(u);
    FichaClinica fc=new FichaClinica();
    em.persist(fc);
    fc.setUtente(u);
    return "Utente "+Integer.toString(u.getCod_utente())+" cirado!";
}

发生以下错误：

我还创建了一个persistence.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
<persistence-unit name="Hospital" transaction-type="JTA">
    <class>Entities.Medico</class>
    <class>Entities.Utente</class>
    <class>Entities.FichaClinica</class>
    <class>Entities.Enfermeiro</class>
    <class>Entities.AtoEnfermagem</class>
    <class>Entities.AtoMedico</class>
    <class>Entities.Consulta</class>
    <class>Entities.Prescricao</class>
    <class>Entities.Encomenda</class>
    <class>Entities.Produto</class>
    <class>Entities.Medicamento</class>
    <properties>
        <property name="javax.persistence.schema-generation.database.action" value="drop-and-create"/>
    </properties>
</persistence-unit>
</persistence>

有人可以帮我理解为什么会这样吗？

我已经解决了这个问题。

问题在于arraylists。 Glassfish不支持这种类型的结构，因此我将其更改为Lists
