I am using Spring Hibernate


How to Use restrictions like following in DAO

Criteria criteria = getSession().createCriteria(Inventory.class);
Criterion itemCodeCriterion = Restrictions.eq("inventoryItem.itemCode",itemCode);
Criterion itemDescriptionCriterion = Restrictions.like("inventoryItem.itemDescription",
itemDescription, MatchMode.ANYWHERE);
criteria.add(itemCodeCriterion);
criteria.add(itemDescriptionCriterion);
return criteria.list();

The Inventory Model has the following definition(Inventory.Java)

private long id;
private InventoryItem inventoryItem;
private StoreHouse storeHouse;
private Organization organization;

and the InventoryItem(Inventoryitem.java) has the following

private long id;
private InventoryItemGroup inventoryItemGroup;
private String itemCode;
private String itemDescription;
private String itemSpecification;


when i ran the Restriction i am getting the error

org.hibernate.QueryException: could not resolve property: inventoryItem.itemCode of: com.realty.model.Inventory at rg.hibernate.persister.entity.AbstractPropertyMapping.propertyException(AbstractPropertyMapping.java:81)
