EJB，JavaFX PU java.lang.IllegalArgumentException:Object:model。Person@7e9d562不是已知的实体类型

我一直在JavaFx应用程序上编程，该应用程序使用两个模型类：

package model;

import java.io.Serializable;
import java.util.ArrayList;
import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;


@Entity
public class Person implements Serializable{

@Id
@GeneratedValue(strategy= GenerationType.AUTO)
private Long id;
@OneToMany(cascade={CascadeType.PERSIST,CascadeType.MERGE},
           fetch=FetchType.EAGER, mappedBy="Person")
private ArrayList<Produkt>  products= new ArrayList<Produkt>();
public Long getId() {
    return id;
}

public void setId(Long id) {
    this.id = id;
}
private  String email;
private  String firstName;
private  String lastName;

private  String tel;
private  String kleurCode;
private  String facebook;

public Person() {
    super();
}

public Person(String firstName, String lastName, String email,String tel, String facebook, String kleurCode) {
    setFirstName(firstName);
    setLastName(lastName);
    setEmail(email);
    setFacebook(facebook);
    setTel(tel);
    setKleurCode(kleurCode);
}

public ArrayList<Produkt> getProducts() {
    return products;
}

public void setProducts(ArrayList<Produkt> products) {
    this.products = products;
}

public void setFacebook(String tel)
{
    this.facebook=tel;
}
public String getFacebook() {
    return facebook;
}
public void setKleurCode(String tel)
{
    this.kleurCode=tel;
}
public String getKleurCode() {
    return kleurCode;
}
public String getTel()
{
    return tel;
}
public void setTel(String tel)
{
    this.tel=tel;
}
public String getFirstName() {
    return firstName;
}

public void setFirstName(String fName) {
    firstName=fName;
}

public String getLastName() {
    return lastName;
}

public void setLastName(String fName) {
    lastName=fName;
}

public String getPrimary() {
    return getEmail();
}

public String getSecondary() {
    return getEmail();
}

public String getEmail() {
    return email;
}

public void setEmail(String fName) {
    email=fName;
}
}

package model;

import java.io.Serializable;
import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.ManyToOne;

@Entity
public class Produkt implements Serializable {
String naam;
@Id
@GeneratedValue(strategy= GenerationType.AUTO)
private Long id;


@ManyToOne(cascade={CascadeType.PERSIST,CascadeType.MERGE},
                                        fetch=FetchType.EAGER)
private Person person;

public Person getPerson() {
    return person;
}

public void setPerson(Person person) {
    this.person = person;
}




public Produkt() {
    super();
}
public Produkt(Person p, String naam){
    p=p;
    naam=naam;
};

public String getNaam() {
    return naam;
}

public void setNaam(String naam) {
    this.naam = naam;
}



public Long getId() {
    return id;
}

public void setId(Long id) {
    this.id = id;
}
}

有人知道我怎么解决这个问题吗

已解决。我重新启动了系统并重新安装了glassfish。现在它起作用了

  package facade;


  import java.util.List;
  import javax.persistence.EntityManager;
  import javax.persistence.EntityManagerFactory;
  import javax.persistence.Persistence;
  import javax.persistence.PersistenceContext;
  import javax.persistence.Query;

  import model.Produkt;

  public class Facade {

  @PersistenceContext(unitName = "EJBModuleDAPU")
  private EntityManager em;


  public Facade()
  {
    em=getEntityManager();
 }

 public void createPerson(Person p) {
    if(em!=null){
        em.persist(p);
    }
    else
    {
        System.out.println("EM was null");
    } 
 }

public void createProduct(Produkt p) {
    em.persist(p);
}

public void editProduct(Produkt p) {
    em.merge(p);

}

public void editPerson(Person p) {
    em.merge(p);

}

public void removePerson(Person p) {
    em.remove(em.merge(p));
}

public void removeProduct(Produkt p) {
    em.remove(em.merge(p));
}

public Person findPerson(Object id) {
    return em.find(Person.class, id);
}

public Produkt findProduct(Object id) {
    return em.find(Produkt.class, id);
}

public List<Person> findAllPerson() {
    Query query = em.createQuery("SELECT m from Person as m");  
    return query.getResultList();
    /*System.out.println(em.toString());
    javax.persistence.criteria.CriteriaQuery cq =    em.getCriteriaBuilder().createQuery();
    cq.select(cq.from(Person.class));
    return em.createQuery(cq).getResultList();*/
}

public List<Person> findAllProdcut() {
    javax.persistence.criteria.CriteriaQuery cq = em.getCriteriaBuilder().createQuery();
    cq.select(cq.from(Produkt.class));
    return em.createQuery(cq).getResultList();
}

protected EntityManager getEntityManager() {
EntityManagerFactory emf = Persistence.createEntityManagerFactory("EJBModuleDAPU");
EntityManager ecm = emf.createEntityManager(); 
return ecm;
} 
}
