Hibernate xml configration

Question

I 'm using xml to configure hibernate and using PostreSQL DBMS, but i get an error. This working when using hibernate.properties file and using configuration progrmatically, but with xml is seems there is little bit tricky.

her is hibernate.cfg.xml file witch is place in resource file :

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

    <session-factory>

        <!-- Database connection settings -->
        <property name="connection.driver_class">org.postgresql.Driver</property>
        <property name="connection.url">jdbc:postgresql://localhost:5432/miniIventory</property>
        <property name="connection.username">postgres</property>
        <property name="connection.password">adsginie2roboform</property>


        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.PostgreSQL82Dialect</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>

        <mapping  class="model.Product"/>
        <mapping  class="model.Purchase"/>

    </session-factory>

</hibernate-configuration>

Here is DatabaseUtil class:

public class DatabaseUtil {
    private static final SessionFactory sessionFactory = buildSessionFactory();

    private static SessionFactory buildSessionFactory() {
        try {
            return new Configuration().configure().buildSessionFactory();
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException("There was an error building the factor");
        }
    }

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

}

Here is the stack trace :

The stack trace say that: Caused by: org.hibernate.PropertyAccessException: Exception occurred inside getter of model.Purchase.idPurchase — Andrea Catania, Jan 28 '16 at 22:15

The Problem is caused not initialized properties. To fix that I have intialize all properties in Purchase class like so :

public class Purchase {
    private LongProperty idPurchase;
    private StringProperty codePurchase;
    private ObjectProperty<LocalDate> datePurchase;
    private DoubleProperty totalHt;
    private DoubleProperty tva;
    private DoubleProperty totalTTC;

    public Purchase() {
        this.idPurchase = new SimpleLongProperty();
        this.codePurchase = new SimpleStringProperty();
        this.datePurchase = new SimpleObjectProperty<>();
        this.totalHt = new SimpleDoubleProperty();
        this.tva = new SimpleDoubleProperty();
        this.totalTTC = new SimpleDoubleProperty();
    }

}

Oh my! What's wrong with long, String, double and LocalDate? Why are you wrapping everything into these Property classes? – JB Nizet Jan 28 '16 at 22:36
Yes, i do , what's the porblem with that ? – abdou amer Jan 28 '16 at 22:43
@abdouamer How are you mapping these things? – Dragan Bozanovic Jan 28 '16 at 22:49

I'd rather ask: what's the point? Imagine your life if, every time you need to use any object (a fork, a spoon, a hammer, etc.), you'd have first to get it out of a plastic bag, use it, and then put it back in the plastic bag. Wouldn't it be annoying? That's basically what you're doing with your code. – JB Nizet Jan 28 '16 at 22:50
But, i plan to use theme in tableview, so every change will be updated automaticaly – abdou amer Jan 28 '16 at 23:00
I map them via Hibernate annotations. – abdou amer Jan 28 '16 at 23:01
So, those XxxProperty classes are JavaFx classes? Your persistent, domain model shouldn't be coupled with JavaFX, which is a GUI framework. Your model should be usable with any other UI framework, on a HTTP server, etc. JavaFX should not be used in the model. – JB Nizet Jan 28 '16 at 23:08
Can you tell me why i should'nt use JavaFx properties with the model – abdou amer Jan 28 '16 at 23:11
Because tomorrow, you might decide to use the same model to implement a web application, or a Swing application, or an SWT application, or a console application, and using JavaFx in those applications makes no sense. The UI layer depends on the model, but not vice-versa. – JB Nizet Jan 29 '16 at 00:00
You're right. So, how can implment observable properties wtih out the need of javaFX Framework, and without violating MVC principles. – abdou amer Jan 29 '16 at 08:12
JavaFX Properties can be used without running a javaFX application. So, I think this means that the model is not coupled with the view. Plz check this [link] (http://stackoverflow.com/questions/23187989/using-javafx-beans-properties-in-model-classes/23188565#23188565) – abdou amer Jan 29 '16 at 08:40
