Hi, I am newbie in Vaadin and I am struggling with some issues.
I create a simple project with an entity: person.
Now I want to create a table and bind it to person entity.
The problem is that I cant connect vaadin with my DB, because I am getting next exception:
GRAVE: Servlet.service() for servlet [Myvaadinproject Application]
in context with path
[/myvaadinproject] threw exception [java.lang.NoClassDefFoundError: com/vaadin/addon/jpacontainer/JPAContainerFactory]
with root cause

The code that triggers the exception is:
public VaadinTestMainView() {
super();
JPAContainer persons = JPAContainerFactory.make(Person.class, MyvaadinprojectApplication.PERSISTENCE_UNIT)
;
persons.addEntity(new Person(null, "Marie-Louise Meilleur", 117, new Country(null,"URU",null)));
// Set up sorting if the natural order is not appropriate
persons.sort(new String[]{"age", "name"},
new boolean[]{false, false});
// Bind it to a component
Table personTable = new Table("The Persistent People", persons);
personTable.setVisibleColumns(new String[]{"id","name","age"});
this.addComponent(personTable);
//buildTree();
setSplitPosition(30);
}
this is my persistence.xml
<?xml version="1.0" encoding="UTF-8"?><persistence-unit name="prueba_vaadin">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<!-- provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider -->

</properties>
</persistence-unit>
Any help would be great. Thanks in advance.
