NullPointerException in StatefulRemoveFactory

javajedi May 12, 2006 8:11 PM

JBoss 4.0.4 CR 2
jboss-EJB-3.0_RC6

I'm trying to deploy a stateful session bean and getting a NullPointerException. Any suggestions would be appreciated:

@Stateful
@Scope(ScopeType.SESSION)
@Name("customerManager")
public class CustomerManagerBean implements CustomerManager {

 @DataModel
 private List<Customer> customers;

 @DataModelSelection
 @Out(required=false)
 private Customer selectedCustomer;

 @Factory("customers")
 public void findCustomers() {
 customers = (List<Customer>) StorageService.getSession().createQuery("from " +
 Customer.class.getName());
 }

 public String select() {
 return "selected";
 }

 @Remove @Destroy
 public void destroy() {}
}
