Not able to retrieve grand children in hibernate JPA

Not able to retrieve grand children in hibernate JPA - java

Configuration has article type as children and article types may have different article types as children.
I am trying to retrieve all configuration and its children (all article type for a configuration).
I don't get parent and child article type here.
I want to retrieve all grant children by using Configuration entity.
This is my configuration entity :-

Issues with JPA and Hibernate library when perform count statement

For the previous week or so, I have been fruitlessly trying to get this JPA library to work.
I can perform simple queries, e.g. find entity by id, or get a collection of entities, etc, however, when I try to perform more complex queries, I always seem to be encounter an error. Can someone please help with debugging this COUNT statement which produces the following stack trace of errors:
Caused by: org.hibernate.query.sqm.InterpretationException: Error interpreting query [SELECT COUNT(a.id) FROM AgreementEntity a]; this may indicate a semantic (user query) problem or a bug in the parser
Caused by: java.lang.NullPointerException
Here is the code which causes the error:
EntityManager em = getFirstEntityManager();
Session session = em.unwrap(Session.class);
// The following line of code causes an error
session.createQuery("SELECT COUNT(a.id) FROM AgreementEntity a");
And here is the entire AgreementEntity class:

You can try count(a) instead of a.id
EntityManager em = getFirstEntityManager();
Session session = em.unwrap(Session.class);
// The following line of code causes an error
session.createQuery("select count(a) from AgreementEntity a ");

Same problem here with count function and group by. I downgraded to 5.4.10.Final version to make it work.

The issue was that I was using an alpha build of the hibernate library instead of a stable build.

Persisting a table with foreign keys using EJB and JPA

I am new to JavaEE and I am having a problem with persisting a table that has foreign keys pointing to the primary key of another table using entity classes and ejb's entity manager. I am using Netbeans.
I have an entity called 'property' and have another entity called 'offer' which holds the foreign key pointing to the primary key of the property. So basically, the logic is that one property can have many offers. Therefore, I am trying to add new offers in the 'offer' table using the entity manager but I am not being able to do it. You can look at the code and see what I maybe missing.

Servlet that connects the JSP with the EJB:
String action = request.getParameter("action");
String currencyType = request.getParameter("ddlCurrencyType");
String amount = request.getParameter("offerAmount");
String propertyIdStr = request.getParameter("hdnbt");

{
if ("".equals(action) & !"".equals(currencyType) & !"".equals(amount) & !"".equals(propertyIdStr))

Date currentTime = new Date();
int propertyId = Integer.parseInt(propertyIdStr);
try {

currentTime = df1.parse(df1.format(currentTime));
} catch (ParseException e) {
}
Buyer buyer = buyerDAO.GetBuyer(1);
Property property = propertyDAO.GetProperty(propertyId);
Offer offer = new Offer("Pending", amount, amount, currentDate, currentTime, buyer, property);
offerDAO.Add(offer);
}
else
{
}
}
request.setAttribute("allProperty", propertyDAO.GetAllProperty());
request.getRequestDispatcher("AdministerProperty.jsp").forward(request, response);
Am I missing something here? I have followed a tutorial which didn't have a foreign key guidance but tried to use my own logic to go around it but it didn't work. I cannot find a reliable source that uses the method similar to me. Most of the resources I find are for Hibernate but I am using EJB.

It seems that the method which retrieves the Property and the method that persists the Offer are run in a separate transactions (DAOs being the Stateless session beans).
That would mean that the Offer is populated and persisted with a detached Property, so the persistence provider is not aware of it.
Not sure why an exception is not raised but you would have to merge the Property first or do the query in the same transaction as you persist the Offer:
#Override
public void Add(Offer offer, int peropertyId) {
Property property = em.find(Property.class, propertyId);
offer.setPeropertyId(property);
em.persist(offer);
}
or
#Override
public void Add(Offer offer, Property peroperty) {
Property managedProperty = em.merge(property);
offer.setPeropertyId(managedProperty);
em.persist(offer);
}

I fixed it. If you look at the code for servlet, it was the problem with my if condition that checks the action parameter. It was meant to be if action is not empty but it checks if action is empty. I found this issue by creating an integer that increments itself when it reaches certain stages within the code.
I think you were right on the fact that I had to do the getting property id and buyer id on the same transaction. Otherwise that would have been the next issue for me. Thank you.

Columns are not populating in tableview on javafx

I have been trying to make the columns show a string of paciente and empleado but still they show empty, the other columns are fine, they show what they supposed to show, but these 2 (paciente and empleado) are still empty. I thought it was because of their properties, that they have different names, i tried that and still they came up empty, can i have some tips on how to do it the right way?

Assuming you have an object variable layoutsos of type Layoutsos that has been persisted to the DB or retrieved from the DB. Here's how your code should look like when persisting the Ordemservico entity.
Ordemservico o = new Ordemservico();
o.getOrdemproducaoList().add(layoutsos);
em.persist(o);
If this is a bi-directional relationship, you should set both side of the relationship before persisting.
Layoutsos layoutsos = new Layoutsos();
Ordemservico o = new Ordemservico();
o.getOrdemproducaoList().add(layoutsos);
layoutsos.getOrdermserviceoList().add(o);
em.persist(layoutsos);
em.persist(o);

How to prevent endless loop in hibernate

I have a rest server and client which uses this API. I have a list of hotels and it had passed well until I added bidirectional dependencies to other entities.After that I start receive an endless array of entities which just repeat the same row in database.
It is my first project with hibernate so may be I made trivial mistakes of novice.
Hotel:
#Entity
#Table(name = "hotels", schema = "", catalog = "mydb")
public class HotelsEntity implements HospitalityEntity{
private int idHotel;
private String name;
private String region;
private String description;
// private byte[] photo;
private HotelPropertyEntity property;
private List<RoomEntity> rooms;
#OneToOne(mappedBy = "hotel")
public HotelPropertyEntity getProperty() {
return property;
}
public void setProperty(HotelPropertyEntity property) {
this.property = property;
}
#OneToMany(mappedBy = "hotel")
public List<RoomEntity> getRooms() {
return rooms;
}
public void setRooms(List<RoomEntity> rooms) {
this.rooms = rooms;
}
#Id
#Column(name = "id_hotel", unique = true)
#GeneratedValue(strategy=GenerationType.AUTO)
public int getIdHotel() {
return idHotel;
}
public void setIdHotel(int idHotel) {
this.idHotel = idHotel;
}
#Basic
#Column(name = "name")
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
#Basic
#Column(name = "region")
public String getRegion() {
return region;
}
public void setRegion(String region) {
this.region = region;
}
#Basic
#Column(name = "description")
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
HotelProperty
#Entity
#Table(name = "hotel_property", schema = "", catalog = "mydb")
public class HotelPropertyEntity {
private int idHotelProperty;
private byte hasPool;
private byte hasTennisCourt;
private byte hasWaterslides;
private HotelsEntity hotel;
#Id
#Column(name = "id_hotel_property", unique = true)
#GeneratedValue(strategy=GenerationType.AUTO)
public int getIdHotelProperty() {
return idHotelProperty;
}
public void setIdHotelProperty(int idHotelProperty) {
this.idHotelProperty = idHotelProperty;
}
#Basic
#Column(name = "has_pool", columnDefinition = "BIT", length = 1)
public byte getHasPool() {
return hasPool;
}
public void setHasPool(byte hasPool) {
this.hasPool = hasPool;
}
#Basic
#Column(name = "has_tennis_court", columnDefinition = "BIT", length = 1)
public byte getHasTennisCourt() {

}
#Basic

public byte getHasWaterslides() {
return hasWaterslides;
}
public void setHasWaterslides(byte hasWaterslides) {
this.hasWaterslides = hasWaterslides;
}
#OneToOne(cascade = CascadeType.ALL)
#JoinColumn(name = "id_hotel_property")
public HotelsEntity getHotel() {
return hotel;
}
public void setHotel(HotelsEntity hotel) {
this.hotel = hotel;
}
Room:
#Entity
#Table(name = "room", schema = "", catalog = "mydb")
public class RoomEntity {
private int idRoom;
private String roomType;
private int peopleCapacity;
private Boolean booked;
private Boolean locked;
private HotelsEntity hotel;
private InventoriesEntity inventory;
private RoomPropertyEntity roomProperty;
#OneToOne(mappedBy = "room")
public RoomPropertyEntity getRoom() {
return roomProperty;
}
public void setRoom(RoomPropertyEntity roomProperty) {
this.roomProperty = roomProperty;
}
#OneToOne
#JoinColumn(name = "id_room")
public InventoriesEntity getInventory() {
return inventory;
}
public void setInventory(InventoriesEntity inventory) {
this.inventory = inventory;
}
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "id_hotel")
public HotelsEntity getHotel() {

}
public void setHotel(HotelsEntity hotel) {
this.hotel = hotel;
}
#Id
#Column(name = "id_room")
public int getIdRoom() {

}
#Basic
#Column(name = "people_capacity")
public int getPeopleCapacity() {

}
public void setPeopleCapacity(int peopleCapacity) {
this.peopleCapacity = peopleCapacity;
}
#Basic
#Column(name = "booked", columnDefinition = "BIT", length = 1)
public Boolean getBooked() {
return booked;
}
public void setBooked(Boolean booked) {
this.booked = booked;
}
#Basic
#Column(name = "locked", columnDefinition = "BIT", length = 1)
public Boolean getLocked() {
return locked;
}
public void setLocked(Boolean locked) {
this.locked = locked;
}
Could you please advise what is a way or ways to tell hibernate to stop this cycle?
p.s
This code contains another one issue. I f I remove one to one dependency and remain only one to many I receive failed to lazily initialize a collection of role: com.example.model.HotelsEntity.rooms, could not initialize proxy - no Session (through reference chain: java.util.ArrayList[0]->com.example.model.HotelsEntity["rooms"])

You need to mark entity as not serializable for JSON. Please use #JsonIgnore or #JsonIgnoreProperties("field") on one of the sides of the relations (the annotation is class-level).
