问题
Please help me to find out the issue.i am a beginner in spring hibernate and using Spring 3 and hibernate 4 in my project, i want to use namedQuery in my application. I have created a named query to fetch data from multiple table using join, but i am getting some issue please correct me if i am doing something wrong here. Vode is below The Entity class:-
@Embeddable
@NamedQuery(
name = "findAllProduct",
query = "SELECT PVPOL.pincode,PO.description"
+" FROM product_vendor_payment_option_location PVPOL"
+" INNER JOIN PVPOL.Payement_Id PID"
+" INNER JOIN PVPOL.pincode PC"
+" INNER JOIN PVPOL.paymentOptions PO"
+" where PVPOL.id = :Payement_Id"
)
public class PRODUCT_VENDOR_PAYMENT_OPTION_LOCATION extends Entity {
@Column(name="id")
@OneToMany(cascade=CascadeType.ALL,fetch=FetchType.EAGER,mappedBy="id")
private Collection<Product_Catalog_Vendor> Payement_Id;
@Column(name="pincode_id")
@OneToMany(cascade=CascadeType.ALL,fetch=FetchType.EAGER,mappedBy="PINCODE_ID")
private Collection<Pincodes> pincode;
@Column(name = "payment_options")
@OneToMany(cascade=CascadeType.ALL,fetch=FetchType.EAGER,mappedBy="payment_options")
private Set<Payment_Options> paymentOptions;
//getters and setters here
}
These are my tables from where i want to fetch the data:-
CREATE TABLE PRODUCT_VENDOR_PAYMENT_OPTION_LOCATION (
ID INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
Payment_Id INTEGER UNSIGNED NOT NULL ,
PINCODE_ID INTEGER UNSIGNED NOT NULL ,
PAYMENT_OPTIONS INTEGER UNSIGNED NOT NULL ,
PRIMARY KEY(ID,Payment_Id, PINCODE_ID) ,
INDEX PRODUCT_VENDOR_PAYMENT_OPTION_LOCATION_FKIndex1(PAYMENT_OPTIONS),
INDEX PRODUCT_VENDOR_PAYMENT_OPTION_LOCATION_FKIndex2(Payment_Id) ,
INDEX PRODUCT_VENDOR_PAYMENT_OPTION_LOCATION_FKIndex3(PINCODE_ID),
FOREIGN KEY(PAYMENT_OPTIONS)
REFERENCES PAYEMENT_OPTIONS(PAYMENT_OPTIONS)
ON DELETE NO ACTION
ON UPDATE NO ACTION,
FOREIGN KEY(Payment_Id)
REFERENCES PRODUCT_CATALOG_VENDOR(Id)
ON DELETE NO ACTION
ON UPDATE NO ACTION,
FOREIGN KEY(PINCODE_ID)
REFERENCES PINCODES(PINCODE_ID)
ON DELETE NO ACTION
ON UPDATE NO ACTION);
CREATE TABLE PAYEMENT_OPTIONS ( PAYMENT_OPTIONS INTEGER UNSIGNED NOT NULL AUTO_INCREMENT, Description VARCHAR(500) NULL ,
PRIMARY KEY(PAYMENT_OPTIONS));
CREATE TABLE PRODUCT_CATALOG_VENDOR (
Id INTEGER UNSIGNED NOT NULL , Prefilled_Response_Id INTEGER UNSIGNED NULL ,
Product_Catalog_Id INTEGER UNSIGNED NOT NULL , User_Id INTEGER UNSIGNED NOT NULL ,
Aud_Create_Time TIMESTAMP NOT NULL , Aud_Update_Time TIMESTAMP NOT NULL ,
PRIMARY KEY(Id) ,INDEX PRODUCT_CATALOG_VENDOR_FKIndex1(Product_Catalog_Id) ,
INDEX PRODUCT_CATALOG_VENDOR_FKIndex2(User_Id) ,INDEX PRODUCT_CATALOG_VENDOR_FKIndex3(Prefilled_Response_Id), FOREIGN KEY(Product_Catalog_Id)
REFERENCES PRODUCT_CATALOG(Product_Catalog_Id)
ON DELETE CASCADE
ON UPDATE NO ACTION, FOREIGN KEY(User_Id) REFERENCES VENDOR(User_Id)
ON DELETE CASCADE ON UPDATE NO ACTION, FOREIGN KEY(Prefilled_Response_Id)
REFERENCES PREFILLED_RESPONSE(Prefilled_Response_Id) ON DELETE NO ACTION
ON UPDATE NO ACTION);
CREATE TABLE PINCODES (
PINCODE_ID INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
PINCODE INTEGER UNSIGNED NOT NULL, Description INTEGER UNSIGNED NULL,
PRIMARY KEY(PINCODE_ID));
In DAO class i am calling namedQuery through:-
Session session = sessionFactory.getCurrentSession();
Query query=(Query) session.getNamedQuery("findAllProduct");
when i am running after deployement , i am getting below error in logs:-

Looking forward for some suggestions...

I suppose you should put your @NamedQuery on Entity (where you have @Entity but not @Embeddable).
Read here: http://docs.oracle.com/javaee/6/api/javax/persistence/NamedQuery.html
