Hi there
Can any one explain how to proceed?
Say,there are two entities
Orders------------->Shipments. Relationship is OnetoOne and Uni-directional.

public class Orders implements Serializable {
@Id
@Basic(optional = false)
@Column(name = "OrderId")
private String orderId;
@Column(name = "OrderName")
private String orderName;
@OneToOne(cascade={CascadeType.PERSIST})
private Shipments objShipment;
}

public class Shipments implements Serializable {
@Id
@Column(name = "ShpmentId")
private String shpmentId;
@Column(name = "City")
private String city;
}

In some cases, I need to delete only Order entity but that deletion should not affect the
Shipment entity at all or it may be vice versa. How to Proceed?
I am stuck.
