Any idea of the reason?

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);
I have a simple project with following entities:

During the save, I'm first saving the authority using authority repository and then user information using user repository.
Not able to figure out why is it crashing. Any help would be greatly appreciated.
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")

#Column(name = "last_name")

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.
I am trying to develop a small web application as training for my upcoming finals and I can't figure out what I'm doing wrong.
These are my *Entities*L Kunde and Konto (many2many-relationship), the auto-created table Kunde_Konto has only the two primary keys of my entities.
#Entity
#NamedQueries({
#NamedQuery(name="findKundeById", query="select k from Kunde k where k.svnr = :svnr"),
})
public class Kunde implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#Column(precision=4, scale=0)
private Long svnr;
#ManyToMany
private List<Konto> konten;
}
#Entity
#NamedQueries({
#NamedQuery(name="findKontoByBesitzer", query="select k from Konto k join k.besitzer b where b.svnr = :svnr")
})
public class Konto implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#Column(precision=4, scale=0)
private Long knr;
#ManyToMany(mappedBy="konten")
private List<Kunde> besitzer;
}
And this is my Managed Bean:
#ManagedBean
#SessionScoped
public class KundenKontoList implements Serializable {
private FacesContext fc = null;
private HttpServletRequest hsr = null;
private HttpSession hs = null;
#EJB
private KontoFacadeLocal kontoFacade;
#EJB
private KundeFacadeLocal kundeFacade;
private Kunde k;
private List<Konto> konten;
/**
* Creates a new instance of KundenKontoList
*/
public KundenKontoList() {
fc = FacesContext.getCurrentInstance();
hsr = (HttpServletRequest) fc.getExternalContext().getRequest();
hs = hsr.getSession();
k = (Kunde) hs.getAttribute("kunde");
konten = kontoFacade.findKontoByBesitzer(k);
}
}
The exception
com.sun.faces.mgbean.ManagedBeanCreationException: Klasse at.pf.controller.KundenKontoList kann nicht instanziiert werden.
which translated means that KundenKontoList can't be instatiated, is thrown at the line:
konten = kontoFacade.findKontoByBesitzer(k);
//method in the facade:
#Override
public List<Konto> findKontoByBesitzer(Kunde k) {
Query q = em.createNamedQuery("findKontoByBesitzer");
q.setParameter("svnr", k.getSvnr());
return q.getResultList();
}
I think that it has something to do with the kontoFacade, but I don't know what the exact problem is.
Fail on init of managedbean, suggests to me that injection of ejbs is failing. Is there a longer error message?
