Hibernate + SQLite not creating database


Question

Here's my problem:

I have a desktop application using JavaFX + Hibernate + SQLite. This is my Model:

    @Entity
@Table(name = "usuario")
public class Usuario implements AbstractModel, Serializable {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Integer id;

    @NotNull @Size(min=5, max=100)
    private String username;

    @NotNull @Size(min=5, max=100)
    private String password;

    @NotNull
    private Boolean administrador;

    @Version
    private Integer version;

    public Usuario() {
    }

    public Usuario(Integer id, String username, String password, Boolean admin, Integer version) {
        this.id = id;
        this.username = username;
        this.password = password;
        this.administrador = admin;
        this.version = version;
    }

    @Override
    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPasword(String password) {
        this.password = password;
    }

    public Boolean getAdministrador() {
        return administrador;
    }

    public void setAdministrador(Boolean administrador) {
        this.administrador = administrador;
    }

    public Integer getVersion() {
        return version;
    }

This is my persistence.xml

    <?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
  <persistence-unit name="PartyRockPU" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <class>br.com.gear7.partyrock.model.Usuario</class>

    <properties>
      <property name="javax.persistence.jdbc.driver" value="org.sqlite.JDBC" />
      <property name="javax.persistence.jdbc.url" value="jdbc:sqlite:party_rock.sqlite" />
      <property name="javax.persistence.jdbc.user" value="" />
      <property name="javax.persistence.jdbc.password" value="" />

      <property name="hibernate.dialect" value="br.com.gear7.partyrock.utils.SQLiteDialect"/>
      <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/>
      <property name="hibernate.connection.charSet" value="UTF-8"/>
      <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
    </properties>
  </persistence-unit>
</persistence>

And finally this is my SQLiteDialect

When I run my application, everything goes smoothly but the database file doesn't get created, meaning that my table also doesn't get created.

Been struggling with this for the past 3 hours and can't find any solution for it.

Accepted Answer

I'm sorry it took me so long, but here is what solved the problem for me. I changed the DIALECT file to a better one that I found.

And I changed this line on my persistence.xml

<property name="hibernate.hbm2ddl.auto" value="update"/>

This solved for me. :)

Just add this < property name="hbm2ddl.auto">create< /property> in persistence.xml. It will work. But other-than create is not working.
