Hi i have these 2 basic entity mapping for postgresql db, and i have wrote criteria for
fetching all activated user which have same key it is showing this error
org.hibernate.QueryException: could not resolve property: key.id of: com.sar.dfsapp.modal.ActivatedUser
#Entity
#Table(name = "activated_user")
public class ActivatedUser implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id", nullable = false, length = 11)
private long id;
#ManyToOne
#JoinColumn(name = "key_id", nullable = false)
private Key key;
}
#Entity
#Table(name = "key")
public class Key implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id", nullable = false, length = 11)
private long id;
#Column(name = "key_code", nullable = false)
private String keyCode;
}
Below is my criteria i have tried.
Criteria c = getSession().createCriteria(ActivatedUser.class);
c.add(Restrictions.eq("key.id", id));
List<ActivatedUser> result = c.list();
try this :
Criteria c = getSession().createCriteria(ActivatedUser.class);
Criteria keyCriteria = criteria.createCriteria("key", CriteriaSpecification.INNER_JOIN);
keyCriteria.add(Restrictions.eq("id", id));
List<ActivatedUser> result = c.list();
it there the same error ?

I am trying to write a JUnit test case for the following search filter method. I am using Querydsl for the search filter. The following method does not depend on Repository; that is why I am not using mockito. This is the first time I am writing a test case for such a method. Please give any suggestions, if you have any?
public List<Tuple> btnSearchClick(String sClientAcctId, String sAcctDesc, String sInvestigatorName,
String sClientDeptId) throws Exception {
QAccount account = QAccount.account;
QDepartment department = QDepartment.department;
QAccountCPCMapping accountCPCMapping = QAccountCPCMapping.accountCPCMapping;
QInvestigator investigator = QInvestigator.investigator;
JPAQuery<Tuple> query = new JPAQuery<Tuple>(em);
query.select(Projections.bean(Account.class, account.sClientAcctId, account.sAcctDesc, account.sLocation,
Projections.bean(Department.class, department.sDeptName, department.sClientDeptId).as("department"),
Projections.bean(Investigator.class, investigator.sInvestigatorName).as("investigator"),
Projections.bean(AccountCPCMapping.class, accountCPCMapping.sCCPCode).as("accountCPC"))).from(account)
.innerJoin(account.department, department).innerJoin(account.accountCPC, accountCPCMapping)
.innerJoin(account.investigator, investigator).where(account.nInstId.eq(60));

Can anyone please tell me what I am doing wrong in my test case, or suggest an alternative to the code above.
Lists are zero-indexed. That means that if your list has only 1 element, it's index will be 0, not 1.
The element with index 1 is actually the second one (which doesn't exist, thus the index out of bounds).
account.get(1)
should be
account.get(0);
hope somebaody can help me. I have two entities related OneToMany.
First:
#Entity
#Table(name = "repartos")
#XmlRootElement
public class Repartos implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Basic(optional = false)
#Column(name = "id")
private Integer id;
#Basic(optional = false)
#NotNull
#Column(name = "fecha")
#Temporal(TemporalType.DATE)
private Date fecha;
#OneToMany(cascade = {CascadeType.ALL}, mappedBy = "repartoId")
public List<RepartosDetalle> repartosDetalleList;
.....
And then the another one:
#Entity
#Table(name = "repartos_detalle")
#XmlRootElement
public class RepartosDetalle implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Basic(optional = false)
#Column(name = "id")
private Integer id;
#JoinColumn(name = "reparto_id", referencedColumnName = "id")
#ManyToOne(optional = false)
private Repartos repartoId;
#Column(name = "descargado")
#Convert(converter = BooleanOneZeroConverter.class)
private boolean descargado;
public RepartosDetalle() {
}
public RepartosDetalle(Repartos repartoId) {
this.repartoId = repartoId;
}
public Repartos getRepartoId() {
return repartoId;
}
public void setRepartoId(Repartos repartoId) {
this.repartoId = repartoId;
}
public boolean isDescargado() {
return descargado;
}
public void setDescargado(boolean descargado) {
this.descargado = descargado;
}
}
What I try to get is all the Repartos given a date and where they have al least one RepartosDetalle with the property descargado=TRUE.
I've been trying with the following query but I do't get any result.
#Override
public List<Repartos> buscarPorFechaDescargados(Date searchDate) {
Query q = em.createQuery("SELECT e FROM Repartos e "
+ "WHERE e.fecha = :searchDate"
+ " AND e.repartosDetalleList.descargado=TRUE");
q.setParameter("searchDate", searchDate);
return q.getResultList();
}
Is there a proper way to make this query using one of the collection's property value?
Thanks a lot and nice weekend.
Try to use JOIN operator on these 2 entities - Repartos and RepartosDetalle :
SELECT e FROM Repartos e JOIN RepartosDetalle d
WHERE e.fecha = :searchDate
AND d.descargado = TRUE
I have two table:
CREATE TABLE [LeTYPE](
[LeNAME] [varchar](100) NOT NULL,
[Le_DESC] [varchar](500) NULL,
[LeFOR] [varchar](50) NOT NULL,
CONSTRAINT [PK_LeTYPE] PRIMARY KEY CLUSTERED
(
[LeNAME] ASC
)
)
CREATE TABLE [Le](
[SN] [int] IDENTITY(1,1) NOT NULL,
[LeNAME_FK] [varchar](100) NOT NULL,
[Le_SN] [int] NULL,
[LOWERRANGE] [float] NOT NULL,
[UPPERRANGE] [float] NOT NULL,
[Le_DESC] [varchar](500) NULL,
[COLOR] [varchar](45) NULL,
CONSTRAINT [Le_pk] PRIMARY KEY CLUSTERED
(
[SN] ASC
))
GO
ALTER TABLE [Le] WITH CHECK ADD CONSTRAINT [FK_Le_LeTYPE] FOREIGN KEY([LeNAME_FK])
REFERENCES [LeTYPE] ([LeNAME])
ON UPDATE CASCADE
ON DELETE CASCADE
GO
ALTER TABLE [Le] CHECK CONSTRAINT [FK_Le_LeTYPE]

One tuple in LETYPE will have many LE.
JPA Entity generated by netbeans:
public class Letype implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#Basic(optional = false)
#NotNull
#Size(min = 1, max = 100)
#Column(nullable = false, length = 100)
private String Lename;
#Size(max = 500)
#Column(name = "Le_DESC", length = 500)
private String LeDesc;
#Basic(optional = false)
#NotNull
#Size(min = 1, max = 50)
#Column(nullable = false, length = 50)
private String Lefor;
#OneToMany(cascade = CascadeType.ALL, mappedBy = "LenameFk", fetch = FetchType.LAZY)
private List<Le> LeList;
}
public class Le implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Basic(optional = false)
#NotNull
#Column(nullable = false)
private Integer sn;
#Column(name = "Le_SN")
private Integer LeSn;
#Basic(optional = false)
#NotNull
#Column(nullable = false)
private double lowerrange;
#Basic(optional = false)
#NotNull
#Column(nullable = false)
private double upperrange;
#Size(max = 500)
#Column(name = "Le_DESC", length = 500)
private String LeDesc;
#Size(max = 45)
#Column(length = 45)
private String color;
#JoinColumn(name = "LeNAME_FK", referencedColumnName = "LeNAME", nullable = false)
#ManyToOne(optional = false, fetch = FetchType.LAZY)
private Letype LenameFk;
}
Now, What I wanted was if I add a LETYPE from JSF view I would like to add multiple LE also at the same time.
LETYPE
-LE1
-LE2
-LE3
Do I need to set LenameFk manually in Le entity since I am getting
*Cannot insert the value NULL into column 'LENAME_FK'*? Why won't it automatically take it from Le enityt?
Note this snippet of code:
public class Le implements Serializable {
...
#ManyToOne(optional = false, fetch = FetchType.LAZY)
private Letype LenameFk;
...
}
optional = false means any instance of this entity must participate the relation, so, the foreign key field can not be null.
Your right, You need to set LenameFk manually in Le entity.
In General , for Bi-directional one-to-many two way relation , Accessor method should like below and assume entities are Customer and Order and one-to-many relation b/w them.
Customer.java
public Collection<Order> getOrders() {
return Collections.unmodifiableCollection(orders);
}
public void addToOrders(Order value) {
if (!orders.contains(value)) {
orders.add(value);
value.setCustomer(this);
}
}
public void removeFromOrders(Order value) {
if (orders.remove(value)) {
value.setCustomer(null);
}
}
Order.java
public void setCustomer(Customer value) {
if (this.customer != value) {
if (this.customer != null) {
this.customer.removeFromOrders(this);
}
this.customer = value;
if (value != null) {
value.addToOrders(this);
}
}
}
public Customer getCustomer() {
return customer;
}
I`m using Eclipse RCP with EJB exposed like WebServices. My services beans looks like follows
#Override
#SuppressWarnings("unchecked")
public List<Author> listAll() {
final Query query = this.entityManager.createQuery("from Author");
final List<Author> authors = query.getResultList();
return authors;
}
The two entityes are:
#Entity
#Table(name = "books")
public class Book implements Serializable {
#Id
private int id;
private String title;
private String summary;
private String isbn;
#Column(name = "published")
private Date publishingDate;
#Column(name = "created")
private Date createdAt;
#Column(name = "updated")
private Date modifiedAt;
#ManyToMany
#JoinTable(
name = "book_authors",
joinColumns = #JoinColumn(name = "book_id", referencedColumnName = "id"),
inverseJoinColumns = #JoinColumn(name = "author_id", referencedColumnName = "id"))
private List<Author> authors;
and
#Entity
#Table(name = "authors")
public class Author implements Serializable {
private static final long serialVersionUID = 1L;
#Id
private int id;
#Column(name = "first_name")
private String firstName;
#Column(name = "middle_name")
private String middleName;
#Column(name = "last_name")
private String lastName;
#Column(name = "created")
private Date createdAt;
#Column(name = "updated")
private Date modifiedAt;
#ManyToMany
#JoinTable(
name = "book_authors",
joinColumns = #JoinColumn(name = "author_id", referencedColumnName = "id"),
inverseJoinColumns = #JoinColumn(name = "book_id", referencedColumnName = "id"))
private List<Book> books;
In my TestWSCLient i`m trying to do something like this
AuthorServiceBeanServiceLocator locator = new AuthorServiceBeanServiceLocator();
AuthorServiceBean service = locator.getAuthorServiceBeanPort();
Author[] authors = service.listAll();
for(Author a : authors){
System.out.println(a.getFirstName());
}
and I`m getting this error
{....//xml.apache.org/axis/}stackTrace:Marshalling Error: failed to lazily initialize a collection of role: ro.cgs.entities.Author.books, no session or session was closed
I`m mention that if I do not make the Many-To-Many relationship all works fine. Can anybody tell me what should I do to fix this problem ?
I use Hibernate for persistence.
Thanks.
I'm trying to implement loading in three tables (the beginning of the problem with mapping)
Products:
#Entity
#Table(name = "products")
public class Product implements Serializable {
#Id
#Column(name = "id")
private Integer id;
#OneToMany(mappedBy = "property", fetch = FetchType.LAZY)
private Collection<ProductProperty> productPropertyCollection;
...
}
Properties:
#Entity
#Table(name = "properties")
public class Property implements Serializable {
#Id
#Column(name = "id")
private Integer id;
#OneToMany(mappedBy = "property", fetch = FetchType.LAZY)
private Collection<ProductProperty> productPropertyCollection;
...
}
Product_Property
#Entity
#Table(name = "product_property")
public class ProductProperty implements Serializable {
#EmbeddedId
protected ProductPropertyPK productPropertyPK;
#MapsId(value = "propertyId")
#JoinColumn(name = "property_id", referencedColumnName = "id")
#ManyToOne()
private Property property;
#MapsId(value = "productId")
#JoinColumn(name = "product_id", referencedColumnName = "id")
#ManyToOne()
private Product product;
...
}
#Embeddable
public class ProductPropertyPK implements Serializable {
#Basic(optional = false)
#NotNull
#Column(name = "product_id", insertable = false, updatable = false)
private int productId;
#Basic(optional = false)
#NotNull
#Column(name = "property_id", insertable = false, updatable = false)
private int propertyId;
...
}
It works fine for 1, 10, 100 products, but somewhere there is an error, because for 1000 and more products throws error:

when i'm creating ProductProperty, i'm setting product and property in ProductProperty, and adding to collection for bidirection in Product and Property.
where i could make a mistake?
Looks like your object model complexity or depth is just difficult to traverse within your JVM's stack limits. As it is, every entity seems reachable from every other entity, which causes problems when traversed recursively. Try increasing the -Xss setting. You might also reduce the interconnectivity, such as removing one of the OneToMany mappings and query for it directly instead of storing it in the Product or Property mapping. You might also file an enhancement with EclipseLink to traverse the object graph using a stack instead of recursively.
