1. Best way to use JPA with relationships java.netAt a time I have a detached (JPA terminology) Permessitemporanei instance in memory. I have to persist the following changes to the database: 1- the associated ingressiconpermesso must be deleted 2- a new ingressiconpermesso must be created 3- statopermesso field must be updated 4- a new Accessiconpermesso must be added to the collection accessiconpermessoCollection |

I wire up the bidirectional relationship correctly and persist the Chassis. I have the persistence logging set to FINEST. I see all of the inserts into the database being performed correctly and I even put a method in to dump the relationships from ... |
4. FK is not populating for JPA- One-to-One NONDirectional Relationship java.netI have a entity called Asset. It is the root entitiy. Inside the root entity are several one-to-one non-directional and one-to-many relationships. Several of these child entities possess subordinate entities and relationships. The subordinate relationships are one-to-many and one-to-one bidirectional relationships. My problem is all the relationships are getting progated correctly for the subordinate entities, but the root entitiy's one-to-one non-directional ... |

I currently have a @ManyToOne uni-directional relationship from the Alarm to the Device (the Alarm knows the associated device but the device does not directly know the alarms associated with it). When a Device entity is removed, I want to ... |
