I'm facing the following problem when i persist an entity using entity manager that acquired by Spring.

java.lang.IllegalArgumentException: Object: org.tts.maqraa.data.Daralquran@183eae7 is not a known entity type.
javax.faces.FacesException: #{configurationChecker.check}: java.lang.IllegalArgumentException: Object: org.tts.maqraa.data.Daralquran@183eae7 is not a known entity type.

Where i'm using the following technologies

Apache Tomcat 7.
Eclipse Link 2.3.2.
Spring 3.0.
JSF 2.0 Mojarra.

Also you can find the Daralquran entity to ensure that the entity is mapped properly.

@Entity
public class Daralquran implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)

    private Date establishedDate;

    private String fullName;

    private String mobileNumber;

    @ManyToMany(mappedBy="daralqurans2", fetch=FetchType.EAGER)
    private List<User> users;

    public Daralquran() {
    }

    public int getId() {
        return this.id;
    }

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

    public Date getEstablishedDate() {
        return this.establishedDate;

    public void setEstablishedDate(Date establishedDate) {
        this.establishedDate = establishedDate;
    }

    public String getFullName() {
        return this.fullName;
    }

    public void setFullName(String fullName) {
        this.fullName = fullName;
    }

    public String getMobileNumber() {
        return this.mobileNumber;
    }

    public void setMobileNumber(String mobileNumber) {
        this.mobileNumber = mobileNumber;
    }

    public String getNote() {
        return this.note;

    public void setNote(String note) {
        this.note = note;
    }

    public String getPhoneNo() {
        return this.phoneNo;
    }

    public void setPhoneNo(String phoneNo) {
        this.phoneNo = phoneNo;
    }

    public City getCity() {
        return this.city;
    }

    public void setCity(City city) {
        this.city = city;
    }

    public Country getCountry() {
        return this.country;
    }

    public void setCountry(Country country) {
        this.country = country;
    }

    public User getUser() {
        return this.user;
    }

    public void setUser(User user) {
        this.user = user;
    }

    public List<User> getUsers() {
