java.util.vector cannot be cast to javax.collections.observablelist

Question

I`m getting this error:

java.util.vector cannot be cast to javax.collections.observablelist

When trying to populate TableView with List

this is my code error occurs on last line

try {
   emf = Persistence.createEntityManagerFactory("shopPu");
   em = emf.createEntityManager();
   List<Products> proList = em.createQuery("select p from Products p").getResultList();
   tableView.setItems((ObservableList<Products>)proList);
} catch (Exception e) {
   JOptionPane.showMessageDialog(null, e.getMessage());
}

How i can bind List to my table or what is correct way to convert List to ObservableList?

Use FXCollections to create an ObservableList.

ObservableList<E> observableList = FXCollections.observableList(list);

Thank i set items but my dataTable does not showing data. Debugger shows that observableList contains 3 rows. Do i need any command to display after setItems? – user525717 Sep 03 '12 at 21:01
@user525717 You should probably ask another question with the relevant code to your problem. – Jeffrey Sep 03 '12 at 21:04
