I am trying to map a table which have composite-id in it using Hibernate. I have a mapper file, an entity class that maps that table and a IdClass that is needed for the composite-id's serialization. But I am getting IllegalArgumentException: expecting IdClass mapping error. Here is the mapper file:

<hibernate-mapping>

    <class name="database.PermissionsEntity" table="Permissions" schema="interapp">

        <composite-id mapped="true" class="database.PermissionsEntityPK">

            <key-property name="id">

                <column name="id" sql-type="int(11)"/>

            </key-property>

            <key-property name="level">

                <column name="level" sql-type="char(1)" length="1"/>

            </key-property>

        </composite-id>

    </class>

</hibernate-mapping>

This is the Entity class I wrote:

@Entity

@Table(name = "Permissions", schema = "interapp", catalog = "")

@IdClass(PermissionsEntityPK.class)

public class PermissionsEntity {

    @Id

    private int id;



    @Id

    private String level;



    public int getId() {

        return id;

    }



    public void setId(int id) {

        this.id = id;

    }



    public String getLevel() {

        return level;

    }



    public void setLevel(String level) {

        this.level = level;

    }



    @Override

    public boolean equals(Object o) {

        if (this == o) return true;

        if (o == null || getClass() != o.getClass()) return false;



        PermissionsEntity that = (PermissionsEntity) o;



        if (id != that.id) return false;

        if (level != null ? !level.equals(that.level) : that.level != null) return false;



        return true;

    }



    @Override

    public int hashCode() {

        int result = id;

        result = 31 * result + (level != null ? level.hashCode() : 0);

        return result;

    }

}

The IdClass that I am using is this:

public class PermissionsEntityPK implements Serializable {

    private int id;

    private String level;



    public PermissionsEntityPK(int id, String level) {

        this.id = id;

        this.level = level;

    }



    public PermissionsEntityPK() {



    }



    @Column(name = "id", nullable = false)

    @Id

    public int getId() {

        return id;

    }



    public void setId(int id) {

        this.id = id;

    }



    @Column(name = "level", nullable = false, length = 1)

    @Id

    public String getLevel() {

        return level;

    }



    public void setLevel(String level) {

        this.level = level;

    }



    @Override

    public boolean equals(Object o) {

        if (this == o) return true;

        if (o == null || getClass() != o.getClass()) return false;



        PermissionsEntityPK that = (PermissionsEntityPK) o;



        if (id != that.id) return false;

        if (level != null ? !level.equals(that.level) : that.level != null) return false;



        return true;

    }



    @Override

    public int hashCode() {

        int result = id;

        result = 31 * result + (level != null ? level.hashCode() : 0);

        return result;

    }

}

I think there maybe some @Id misplacement, but I can't figure out where. What am I missing here?
