[eclipselink-users] New instances and resolving mappings

[Clogs <Willem.Kunkels@xxxxxxxxxxxxxx>]

Hello all, 

I am faced with a problem which I am unable to get a grip on. This is the
scenario: 

I instantiate a POJO which is annotated as an Entity. In the POJO there are
annotations which are used to reference other tables in the database, like: 

    @ManyToOne(fetch=FetchType.LAZY,optional=false) 
    @JoinColumn(name="LEVNR", referencedColumnName = "LEVNR", insertable =
false, updatable = false) 
    private Leverancier leverancier; 

    public Leverancier getLeverancier() { 
        return leverancier; 
    } 
    public void setLeverancier(Leverancier leverancier) { 
        this.leverancier = leverancier; 
    } 

When I now invoke getLeverancier() on the instantiated object, I would
expect a trip to the database to get the information. However, this never
happens, 'leverancier' remains null and the application falls over. The
information to retrieve the required leverancier is set-up correctly
(LEVNR). 

Does the newly created entity need be managed in order for mappings to work? 
Am I overlooking anything? 

Thanks...all help is appreciated
