Re: Can I use eclipselink to get the differences between two objects?

Is it possible to make it consider @OneToMany mappings also?

It will report a difference no matter what I put into the @OneToMany set, even if the objects themself are equal if passed into the  createObjectChangeSetThroughComparison method.

I would like to work with a object graph rather than with individual objects.

Under the covers api's are not a problem.

I currently do it like this:

    @Autowired
    private JpaEntityManager entityManager;

    private final ObjectChangePolicy objectChangePolicy = new DeferredChangeDetectionPolicy();

    public ObjectChangeSet compare(final AbstractEntity original, final AbstractEntity copy) {
        ObjectChangeSet objectChangeSet = this.objectChangePolicy.createObjectChangeSetThroughComparison(original, copy,
            (UnitOfWorkChangeSet) this.entityManager.getUnitOfWork().getCurrentChanges(), false, (AbstractSession) this.entityManager
                .getActiveSession(), this.entityManager.getActiveSession().getDescriptor(original.getClass()));

        return objectChangeSet;
    }

Thanks!
