It seems as though the RequestBean EJB is not getting injected into the
OrderManager ManagedBean
@ManagedBean
@SessionScoped
public class OrderManager {
private static final Logger logger = Logger
.getLogger("order.web.OrderManager");
private Boolean findVendorTableDisabled = true;
private Boolean partsTableDisabled = true;
private Integer currentOrder;
private Integer newOrderId;
private List<Part> newOrderParts;
private List<Part> newOrderSelectedParts;
private List<Order> orders;
private List<String> vendorSearchResults;
private Long selectedVendorPartNumber;
@EJB
private RequestBean request;
private String newOrderShippingInfo;
private String selectedPartNumber;
private String vendorName;
private char newOrderStatus;
private int newOrderDiscount;
private int selectedPartRevision;
/**
* @return the orders
*/
public List<Order> getOrders() {
try {
// request == null <<------- ERROR HERE!!
this.orders = request.getOrders();
} catch (Exception e) {
e.printStackTrace();
}
return orders;
}
// more code here...
}
The exception is as follows:
