Can somebody help me create a query that selects all rows within a table. I'm
trying to build an SelectItems boject that contains all the states within the
US. I get a ClassCastException each time I try to render the page that has my
selectitem component. I looked at the jboss-seam-booking.ear and it is similar
to what the BookListAction.java class, but I don't have an @In value and when I
do create an @In value of state it gives me another exception.
I created a local EJB called StateList.java
| @javax.ejb.Local
| public interface StateList{
| public List<State> list();
| }
|
Then I try to implement it in StateListAction.java
| public class StateListAction implements StateList{
| @PersistenceContext
| EntityManager em;
| .................
| public List<State> list(){
| List<State> list = em.createQuery("select id, name from State");
| ...
| or
| List<State> list = em.createQuery("from State");
| return list;
| }
| }
