JPAContainerFactory does not create the database table

Question

I expected JPAContainer to create a database table automatically when 'hbm2ddl.auto' is set to 'update', however this seems to not be the case. Is there something wrong in my configuration or should i use something else to get the desired functionality?

I am using the following command to create a JPAContainer

accounts = JPAContainerFactory.make(Account.class, RumUI.PERSISTENCE_UNIT);

The Accounts class is

@Entity
@Table(name="accounts")    
public class Account implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(generator="increment")
    @GenericGenerator(name="increment", strategy = "increment")
    private Long id;

    @NotNull
    @Size(min = 2, max = 24)
    @Column(name = "name", unique=true)
    private String name;

    @NotNull
    @Email
    @Column(name = "email")
    private String email;

    @NotNull
    @Size(min = 2, max = 24)
    @Column(name = "password")
    private String password;

    @NotNull
    @Column(name = "role")
    private String role;

    public Account() {
    }

    //getters and setters

}

And the persistence.xml

<persistence-unit name="RuM">
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
        <class>ee.ut.cs.rum.domain.Account</class>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
            <property name="hibernate.connection.url" value="jdbc:postgresql://127.0.0.1:5432/RuM"/>
            <property name="javax.persistence.jdbc.driver" value="org.postgresql.Driver"/>
            <property name="hibernate.connection.username" value="postgres"/>
            <property name="hibernate.connection.password" value="postgres"/>
            <property name="hibernate.show_sql" value="true"/>
            <property name="hibernate.format_sql" value="true"/>
            <property name="hbm2ddl.auto" value="update"/>
            <property name="hibernate.current_session_context_class" value="thread" />
        </properties>
    </persistence-unit>

I would expect that the database table 'accounts' would be created automatically since 'hbm2ddl.auto' is set to 'update'. However the table is not created.

If i create Hibernate ServiceRegistry and SessionFactory directly using the same settings (using a Configuration object), then the table is created.

What am i missing here?

The entity annotation was missing from my question, but was present in the actual source. Otherwise ServiceRegistry and SessionFactory would also not have worked. But thank you for noticing. I have edited the question accordingly. – FableBlaze Apr 12 '15 at 03:31
How do you solve the question? l want to learn this.Thank you ! – Andy Ying Apr 12 '15 at 06:24

can you show your applicationContext.xml .`accounts = JPAContainerFactory.make(Account.class, RumUI.PERSISTENCE_UNIT);` l never use this in my jpa project. I want to know ,why you need this. – Andy Ying Apr 12 '15 at 14:26
I believe that vaadin has applicationcontext.xml file. It least i do not seem to have one in my project. My project is based on the default Vaadin project. – FableBlaze Apr 12 '15 at 17:23
Can you tell me what frame are you use in your project? – Andy Ying Apr 13 '15 at 04:54

Tried it and 'hbm2ddl.auto' == 'update' setting is still ignored. I feel that it is Vaadin's JPAContainer specific – FableBlaze Apr 12 '15 at 12:48
