Question

I'm showing you the class that already I've got and I would like to serialize with jaxb. Unluckly when I try to serialize positionSet inside Person I can't obtain completely all the attribute that there are inside the Person object

Code:

    public class Person {   
        @Id
        @Column(name = "ID")
        private Integer id;

        @Column(name = "FIRST_NAME")
        @NotNullOnlyJsp
        private String firstName;

        @Column(name = "LAST_NAME")
        @NotNullOnlyJsp
        private String lastName;    

        @OneToMany(cascade = { CascadeType.ALL }, fetch = FetchType.LAZY, mappedBy = "person")
        @org.hibernate.annotations.OrderBy(clause = "start_date asc")
        private Set positionSet = new LinkedHashSet();

        // getter and setter and other methods..    

    }

    public class Position{

        @Id
        @Column(name = "ID")
        private Integer id;

        @Column(name = "FK_PERSON")
        @NotNull
        private Integer personId;

        @Column(name = "FK_POSITION_TYPE")
        @NotNull
        private Integer positionTypeId;

        @ManyToOne(fetch = FetchType.LAZY)
        @JoinColumn(name = "FK_POSITION_TYPE", insertable = false, updatable = false)
        private Entity positionType;


        @ManyToOne(fetch = FetchType.LAZY)
        @JoinColumn(name = "FK_PERSON", insertable = false, updatable = false)
        // I need this annotation to avoid ciclyc graph
        @XmlInverseReference(mappedBy="positionSet")
        private Person person;

        @Column(name = "FK_ORG_UNIT")
        @NotNull
        private Integer organizationUnitId;

        @ManyToOne(fetch = FetchType.LAZY)
        @JoinColumn(name = "FK_ORG_UNIT", insertable = false, updatable = false)
        // I need this annotation to avoid ciclyc graph
        @XmlInverseReference(mappedBy="organizationUnitPositionSet")
        private OrganizationUnit organizationUnit;


    // getter and setter and other methods..    
    }


    public class OrganizationUnit{

        @Id
        @Column(name = "ID")
        private Integer id;

        @ManyToOne(fetch = FetchType.LAZY)
        @JoinColumn(name = "FK_ORG_UNIT_TYPE", insertable = false, updatable = false)
        private OrganizationUnitType organizationUnitType;

        @Column(name = "FK_ORG_UNIT_TYPE")
        private Integer organizationUnitTypeId;

        @Column(name = "DESCRIPTION", length = 4000)
        @NotNull
        private String description;

        @OneToMany(cascade = { CascadeType.ALL }, fetch = FetchType.LAZY, mappedBy = "organizationUnit")
        @org.hibernate.annotations.OrderBy(clause = "start_date asc")
        // I need this annotation to avoid ciclyc graph
        private Set organizationUnitPositionSet = new LinkedHashSet();

        // getter and setter and other methods..    
    }

Now As you can understand the relations are: Person One to Many Position Many to One OrganizationUnit Position has two properties: "positionType" and "organizationUnit" that references to OrganizationUnit When jaxb serialize I can see only the positionType element and anything about the organizationUnit element inside Position. I tried to check that the Position contains value and I figured out that the data are available inside the object. The difference between positionType and organizationUnit property inside Position Class is the @XmlInverseReference annotation that I need for organizationUnit property mapped by OrganizationUnit class while I don't need this annotation for positionType.

How Could I solve this problem? Why doesn't the annotation allow me to access to organizationUnit inside Position?

I hope that someone could help me. For showing you that it serialize but not correctly I'll show you the xml output file: I can't see organizationUnit property

I simply solved by removing the annotation @XmlInverseReference on organizationUnit property inside Position class and I specified xml-transient for the property positionSet inside OrganizationUnit Class
