Persisting a table with foreign keys using EJB and JPA

Persisting a table with foreign keys using EJB and JPA - java

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 ("Offer".equalsIgnoreCase(action))
{
if ("".equals(action) & !"".equals(currencyType) & !"".equals(amount) & !"".equals(propertyIdStr))
{
DateFormat df = new SimpleDateFormat("dd/MM/yy");
DateFormat df1 = new SimpleDateFormat("HH:mm:ss");
Date currentDate = new Date();
Date currentTime = new Date();
int propertyId = Integer.parseInt(propertyIdStr);
try {
currentDate = df.parse(df.format(currentDate));
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.

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.

For each save (update) hibernate envers creating revisions either changed in table or not

In my client server application, I am using JavaFx as client and Java hibernate as server to db connection.
Problem
I have one save button and for each click on button, envers creates one revision, whether there is no change in table values.
Basically it is not checking old data to new data, just creating revisions.
Here is my bean code

With normal standalone program it is working fine.

Sorry I didn't see this soon, but the problem is your call to session#save. From the javadocs for Session here, you'll notice the following passage:
save() and persist() result in an SQL INSERT, delete() in an SQL DELETE and update() or merge() in an SQL UPDATE. Changes to persistent instances are detected at flush time and also result in an SQL UPDATE. saveOrUpdate() and replicate() result in either an INSERT or an UPDATE.
So you basically want to use session#saveOrUpdate so that you get both insert and update semantics based on the state of your entity.
Since session#save is generating a new INSERT operation, Envers will always create a new revision for that case regardless.

Appointment App - AngularJS availability selection

I developed an application using Java Spring (backend api), mysql (DB) and Anguljar JS (frontend) that is designed to let users schedule an appointment. The endtime of each appointment is five minutes after its starttime, between 8 o’clock and 2 p.m.
In my data base I have the following information:
• A table named “turno” which contains the parameters time and date of the appointments given.
• Another table contains all the available appointments.
I want to substract both arrays so as to see which appointments have not been given yet. The objective is not to allow users to fix an appointment that has already been made by someone else.
Does anyone have any idea how to do this?
Data examples:
Java Example:
#Entity
#Table(name = "turno")
public class Turno implements Serializable {
private static final long serialVersionUID = 1L;
private Long id;
private String solicitante;
private String telefono;
private TipoDocumento tipoDocumento;
private String numeroDocumento;
private String email;
private Horario horario;
private String numeroTurno;
private String fecha;
private Date formatfecha;
private Date controlFecha;
#Id
#GeneratedValue
#Column(name = "id")
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
#Column(name = "solicitante")
public String getSolicitante() {
return solicitante;
}
public void setSolicitante(String solicitante) {
this.solicitante = solicitante;
}
#Column(name = "telefono")
public String getTelefono() {
return telefono;
}
public void setTelefono(String telefono) {
this.telefono = telefono;
}
#Column(name = "numero_documento")
public String getNumeroDocumento() {
return numeroDocumento;
}
public void setNumeroDocumento(String numeroDocumento) {
this.numeroDocumento = numeroDocumento;
}
#Column(name = "email")
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
#ManyToOne(cascade = CascadeType.MERGE)
#JoinColumn(name = "horario", referencedColumnName = "id")
public Horario getHorario() {
return horario;
}
public void setHorario(Horario horario) {
this.horario = horario;
}
#Column(name = "numero_turno")
public String getNumeroTurno() {
return numeroTurno;
}
public void setNumeroTurno(String numeroTurno) {
this.numeroTurno = numeroTurno;
}
#Column(name = "fecha")
public String getFecha() {
return fecha;
}
public void setFecha(String fecha) {
this.fecha = fecha;
}
#Column(insertable = false, updatable = false, name = "fecha")
public Date getFormatFecha() {
return formatfecha;
}
public void setFormatFecha(Date formatfecha) {
this.formatfecha = formatfecha;
}
#ManyToOne(cascade = CascadeType.MERGE)
#JoinColumn(name = "tipoDocumento", referencedColumnName = "id")
public TipoDocumento getTipoDocumento() {
return tipoDocumento;
}
public void setTipoDocumento(TipoDocumento tipoDocumento) {
this.tipoDocumento = tipoDocumento;
}
#Column(name = "fecha_control")
public Date getControlFecha() {
return controlFecha;
}
public void setControlFecha(Date controlFecha) {
this.controlFecha = controlFecha;
}
#Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((numeroTurno == null) ? 0 : numeroTurno.hashCode());
return result;
}
#Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
Turno other = (Turno) obj;
if (numeroTurno == null) {
if (other.numeroTurno != null)
return false;
} else if (!numeroTurno.equals(other.numeroTurno))
return false;
return true;
}
}
Updated

Heres how I fixed it in case anyone is interested:
Method in the controller:
#RequestMapping(value = "/horario/{fecha}", method = RequestMethod.GET)
#ResponseBody
public Object queryHorariosLibres(#PathVariable("fecha") Date fecha) {
List<Long> horariosLibres = null;
List<Long> turnosTomados = turnoService.getTurnosTomados(fecha);
Calendar dia = new GregorianCalendar();
dia.setTime(fecha);
Horario horario = horarioRepository.findByDia(dia.get(Calendar.DAY_OF_WEEK));
horariosLibres = horario.getHorariosLibres(turnosTomados);
if (horariosLibres == null) {
return "hola";
}
else
return horariosLibres;
}
Local methods:
#Transient
public List<Long> getHorarios(){
List<Long> horarios = new ArrayList<Long>();
for(Long i = horarioInicio; i <= horarioFin; i+=300){
horarios.add(i);
}
return horarios;
}
#Transient
public List<Long> getHorariosLibres(List<Long> horariosTomados){
List<Long> horariosLibres = getHorarios();
horariosLibres.removeAll(horariosTomados);
return horariosLibres;
}

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);

Error " java.lang.IllegalStateException: During synchronization a new object was found through a relationship that was not marked cascade PERSIST"

this is my first post, so please bear with me if i do make any errors.
I get an error " java.lang.IllegalStateException: During synchronization a new object was found through a relationship that was not marked cascade PERSIST"
whenever i want to query(add,edit,delete) the database.
The tables related are sponsors and donations. There is a one to many relationship between them. Classes below:
Sponsors
#Entity
#Table(name = "SPONSORS")
#NamedQueries({
#NamedQuery(name = "Sponsors.findAll", query = "SELECT s FROM Sponsors s")})
public class Sponsors implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#Basic(optional = false)
#Column(name = "SPONSORID")
private Short sponsorid;
#Basic(optional = false)
#Column(name = "NAME")
private String name;
#Basic(optional = false)
#Column(name = "SURNAME")
private String surname;
#Basic(optional = false)
#Column(name = "ADDRESS")
private String address;
#OneToMany(cascade = CascadeType.ALL, mappedBy = "sponsorid")
private List<Donations> donationsList;
public Sponsors() {
}
public Sponsors(Short sponsorid) {
this.sponsorid = sponsorid;
}
public Sponsors(Short sponsorid, String name, String surname, String address) {
this.sponsorid = sponsorid;
this.name = name;
this.surname = surname;
this.address = address;
}
public Short getSponsorid() {
return sponsorid;
}
public void setSponsorid(Short sponsorid) {
this.sponsorid = sponsorid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSurname() {
return surname;
}
public void setSurname(String surname) {
this.surname = surname;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public List<Donations> getDonationsList() {
return donationsList;
}
public void setDonationsList(List<Donations> donationsList) {
this.donationsList = donationsList;
}
#Override
public int hashCode() {
int hash = 0;
hash += (sponsorid != null ? sponsorid.hashCode() : 0);
return hash;
}
#Override
public boolean equals(Object object) {

return false;
}
return true;
}
#Override
public String toString() {
return "Pat.Sponsors[ sponsorid=" + sponsorid + " ]";
}
}
Donations:
#Entity
#Table(name = "DONATIONS")
#NamedQueries({
#NamedQuery(name = "Donations.findAll", query = "SELECT d FROM Donations d")})
public class Donations implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#Basic(optional = false)
#Column(name = "DONATIONID")
private Short donationid;
#Basic(optional = false)
#Column(name = "DONATIONDATE")
#Temporal(TemporalType.DATE)
private Date donationdate;
// #Max(value=?) #Min(value=?)//if you know range of your decimal fields consider using these annotations to enforce field validation
#Column(name = "DONATIONAMOUNT")
private Double donationamount;
#JoinColumn(name = "SPONSORID", referencedColumnName = "SPONSORID")
#ManyToOne(optional = false)
private Sponsors sponsorid;
public Donations() {
}
public Donations(Short donationid) {
this.donationid = donationid;
}
public Donations(Short donationid, Date donationdate) {
this.donationid = donationid;
this.donationdate = donationdate;
}
public Short getDonationid() {
return donationid;
}
public void setDonationid(Short donationid) {
this.donationid = donationid;
}
public Date getDonationdate() {
return donationdate;
}
public void setDonationdate(Date donationdate) {
this.donationdate = donationdate;
}
public Double getDonationamount() {
return donationamount;
}
public void setDonationamount(Double donationamount) {
this.donationamount = donationamount;
}
public Sponsors getSponsorid() {
return sponsorid;
}
public void setSponsorid(Sponsors sponsorid) {
this.sponsorid = sponsorid;
}
#Override
public int hashCode() {
int hash = 0;
hash += (donationid != null ? donationid.hashCode() : 0);
return hash;
}
#Override
public boolean equals(Object object) {
// TODO: Warning - this method won't work in the case the id fields are not set
if (!(object instanceof Donations)) {
return false;
}
Donations other = (Donations) object;
if ((this.donationid == null && other.donationid != null) || (this.donationid != null && !this.donationid.equals(other.donationid))) {
return false;
}
return true;
}
#Override
public String toString() {
return "Pat.Donations[ donationid=" + donationid + " ]";
}
}

The field
#ManyToOne(optional = false)
private Sponsors sponsorid;
in the Donations entity is not configured for cascading. Try changing it to:
#ManuToOne(optional = false, cascade = CascadeType.ALL)
private Sponsors sponsorid;
