Hibernate Search with Jpa 2 and lucene java.lang.ClassNotFoundException - java

I am writing an application where i am trying to make an example on hibernate search with Lucene.
In my database, i got an array named A_ROLE witch contains an ID field and a NAME field. Into this array i have store the data bellow:
1 - Agalloh
2 - Rorry Galaher
3 - Isis Isis
My entity class looks like this:
#Entity
#Table(name="A_ROLE")
#NamedQuery(name="ARole.findAll", query="SELECT a FROM ARole a")
#Indexed
public class ARole implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#DocumentId
#SequenceGenerator(name="A_ROLE_ID_GENERATOR", sequenceName="A_ROLE_SEQ")
#GeneratedValue(strategy=GenerationType.SEQUENCE, generator="A_ROLE_ID_GENERATOR")
#Column(unique=true, nullable=false, precision=38)
#Field(index=Index.YES, analyze=Analyze.YES, store=Store.NO)
//#NumericField
private long id;
#Column(length=50)
#Field(index=Index.YES, analyze=Analyze.YES, store=Store.NO)
private String name;
//bi-directional many-to-many association to APermission
#ManyToMany
#JoinTable(
name="A_ROLE_PERMISSION"
, joinColumns={
#JoinColumn(name="ROLE_ID", nullable=false)
}
, inverseJoinColumns={
#JoinColumn(name="PERMISSION_ID", nullable=false)
}
)
private List<APermission> APermissions;
//bi-directional many-to-many association to AUser
#ManyToMany(mappedBy="ARoles")
private List<AUser> AUsers;
constructor, getters and setters
and i have create an interface named DataBaseExchanges which contains a method lucinExample(). This method is responsible for the hibernate search and its implementation is being from the class bellow
import ec.ep.europarl.appdif.db.entity.ARole;
import ec.ep.europarl.appdif.service.DataBaseExchanges;
import java.util.List;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.hibernate.search.jpa.FullTextEntityManager;
import org.hibernate.search.query.dsl.QueryBuilder;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
#Service("dataSearch")
public class DataBaseExchangesImpl implements DataBaseExchanges {
#PersistenceContext
public EntityManager em;
#Override
#Transactional
public void lucinExample() {
FullTextEntityManager fullTextEntityManager =
org.hibernate.search.jpa.Search.getFullTextEntityManager(em);
//em.getTransaction().begin();
QueryBuilder qb =
fullTextEntityManager.getSearchFactory().buildQueryBuilder()
.forEntity(ARole.class).get();
org.apache.lucene.search.Query query = qb
.keyword()
.onFields("name")
.matching("agalloh")
.createQuery();
// wrap Lucene query in a javax.persistence.Query
org.hibernate.search.jpa.FullTextQuery persistenceQuery =
fullTextEntityManager.createFullTextQuery(query, ARole.class);
// execute search
List result = persistenceQuery.getResultList();
em.close();
}
}
i call this method from a controller, where i have #Autowird the above mentioned interface.
When i debug the above functionality it stops at this line of the implementation code:
org.hibernate.search.jpa.FullTextQuery persistenceQuery =
fullTextEntityManager.createFullTextQuery(query, ARole.class);
with error report:

I can't figure out what the problem is, at my maven dependencies i have include hibernate search 4.5.0.Final.
Please can anyone help on this?


Finally i got answer to my question, i realize that i haven't include this in pom file:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.3.4.Final</version>
</dependency>

adding a foreign key into databases

guys i am making a grid library that uses hibernate and spring mvc to read data from db .. i have 2 table employee which has EPMID, EMPNAME, EMPAGE, SALARY, ADDRESS, department_id (refrences to department_id in department table ) and department which has department_id and name ... here is the Department.java
public class Department {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "department_id")
private int depId;
#Column(name = "name")
private String depName;
#OneToMany(mappedBy="department",cascade = { CascadeType.ALL }, orphanRemoval=true)
private List<Employee> employees;}
Employee.java
public class Employee {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "EMPID")
private int empId;
#Column(name = "EMPNAME")
private String empName;
#Column(name = "ADDRESS")
private String empAddress;
#Column(name = "SALARY")
private String salary;
#Column(name = "EMPAGE")
private int empAge;
#ManyToOne(cascade={CascadeType.ALL})
#JoinColumn(name="department_id")
private Department department;}
and the function that adds teh employee in service
public void addEmployee(String[] list, Employee employee) {
employee.getDepartment().setDepId(Integer.parseInt(list[3]));
employee.setEmpName(list[2]);
employee.setEmpAge(Integer.parseInt(list[4]));
employee.setEmpAddress(list[6]);
employee.setSalary(list[1]);
this.employeeDao.addOrEditEmployee(employee);
everything goes fine without that line employee.getDepartment().setDepId(Integer.parseInt(list[3])); but i want to add foreign key to reference on the primary one ..
here is the exception

Do NOT maintain foreign keys using something like this
employee.getDepartment().setDepId(Integer.parseInt(list[3]));
Instead do
Department dept = departmentDao.findById(Integer.parseInt(list[3]));
employee.setDepartment(dept);
Hibernate will now create the database relationship between department and employee by inserting the department_id in the employee table.
P.S. I am assuming some class and method names as I do not have all of your code.
Regarding the NPE
I believe you received a null pointer exception because employee doesn't have a department at that point.
employee.getDepartment().setDepId(...

Getting java.sql.SQLException: Invalid column name with hibernate

Getting java.sql.SQLException: Invalid column name even though column with same name are in table. what can be a reason?
I am trying to call sp with below code:
Session session = HibernateUtil.getSessionFactory().openSession();
Query query = session.getNamedQuery("EMPLOYEE.PRC_HB_EMP_SP1");
query.setParameter("IN_EMPID", empId);
List<Employee> empList = query.list();
System.out.println(empList);
Entity class Employee:
#Entity

#Column(name = "ADDRESS")
private String empAddress;
#Column(name = "SALARY")

#Column(name = "EMPAGE")
private Integer empAge;
............
}
here is sp:
create or replace PROCEDURE PRC_HB_EMP_SP1

Out_value OUT SYS_REFCURSOR,
IN_EMPID NUMBER
)
AS
BEGIN
open Out_value for
SELECT EMPID,EMPNAME
FROM EMPLOYEE
WHERE EMPID = IN_EMPID;
END PRC_HB_EMP_SP1;

Your mappings contain columns ADDRESS,SALARY and EMPAGE but those are missing from your SP.You need to include those in your statement.

org.hibernate.InstantiationException: Cannot instantiate abstract class or interface

I have the following entity:
#Entity
#Table(name = "davt_compensation_service")
#Inheritance(strategy = InheritanceType.JOINED)
#JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})
public abstract class Compensation<C extends Compensation> extends AutoIdBasedEntity {
//properties, setters and getters, equals and hashcode overrides.
}
The rest inherit from it (one of them for example):
#Entity
#Table(name = "davt_compensation_service_relocation")
public class RelocationCompensation extends Compensation<RelocationCompensation> {
//properties, setters and getters, equals and hashcode overrides
}
A parent entity that contains a collection of Compensations:
#Entity
#Table(name = "davt_compensation_case")
#EntityListeners({CompensationCaseNumberListener.class})
#JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})
public class CompensationCase extends AutoIdBasedEntity {
#Valid
#OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL, mappedBy = "compensationCase", orphanRemoval = true)
#MapKey(name = "conceptType")
private Map<ConceptType, Compensation> compensationServices = new HashMap<>();
}
Last but not least, I have a the main entity CompensationFile which has a collection of CompensationCase entities:
#Entity
#Table(name = "davt_compensation_file")
#JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})
public class CompensationFile extends AutoIdBasedEntity {
#Valid
#OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL, mappedBy = "compensationFile", orphanRemoval = true)
private Set<CompensationCase> compensationCases;
}
It's strange because this used to work and suddenly it started working up. For some reason it only happens when updating and existing CompensationCase and adding a new Compensation. For example, if I am persisting an entirely new main CompensationCase, it works without a hitch. I use the JpaRepository method save on the main entity CompensationFile to persist the entire thing as shown below (and where it is throwing the exception):
CompensationFileFormService:
#Service
public class CompensationFileFormService {
#Autowired
private CompensationFileRepository compensationFileRepository;
#Autowired
private CompensationFileFormConverter compensationFileFormConverter;
#Autowired
private CompensationCaseService compensationCaseService;
public CompensationFileForm saveCompensationFile(CompensationFileForm compensationFileForm) throws TaskNotFoundException, InvalidServiceTypeException, CompensationFileNotFoundException, CompensationCaseNotFoundException {
CompensationFile compensationFile = compensationFileFormConverter.convertToCompensationFile(compensationFileForm);
//EXCEPTION IS THROWN HERE
CompensationFile newCompensationFile = compensationFileRepository.save(compensationFile);
if (!newCompensationFile.getCompensationCases().isEmpty()) {
for (CompensationCase compensationCase : newCompensationFile.getCompensationCases()) {
compensationCaseTaskService.save(compensationCase, compensationCase.getAssignedPersonnel());
}
}
return createCompensationFileForm(newCompensationFile.getId(), newCompensationFile.getControlId(), compensationFileForm.getSelectedCompensationCase().getId());
}
}
CompensationFileRepository:
public interface CompensationFileRepository extends JpaRepository<CompensationFile, Long>, JpaSpecificationExecutor<CompensationFile> {
}

Any help at all will be appreciated.

For others that the above solutions might not work, give this a thought and a try afterwards:
When you have you child entities inherit parent entity you will not be able to instantiate the Parent itself but you should instantiate the child that has the parents properties -
For example i had Parent abstract class Profile and i had a child class StudentProfile that extended it. I tried instantiating a list of profiles and it threw the exception(I had data in the profile table in the database but i forgot to add data to the StudentProfile table(and connect them through the for foreign key column - in my case id)
My solution was to add the corresponding data to the StudentProfile table and then i was able to get rid of the exception.
Hope this helps!!

Ok, so it turns out some of the entities that inherited from Compensation had properties with ManyToOne relations and they were missing cascade annotations. Because they were more than one property, I received no TransientPropertyValueException and instead it tried to load the parent Compensation entity which was the closest thing that it could associate the entity to without those fields that weren't being cascaded. Which means that this whole problem was due to missing cascade annotations.
For example:
#Entity
#Table(name = "davt_compensation_service_relocation")
public class RelocationCompensation extends Compensation<RelocationCompensation> {
#Valid
#ManyToOne(fetch = FetchType.EAGER)
#JoinColumn(name = "phone_id")
#ForeignKey(name = "FK_relocationCompensation_phone")
private Phone phone = new Phone();
#Valid
#ManyToOne(fetch = FetchType.EAGER)
#JoinColumn(name = "address_id")
#ForeignKey(name = "FK_relocationCompensation_address")
private Address address = new Address();
//rest of properties, setters and getters, equals and hashcode overrides
}
Changed to:
#Entity
#Table(name = "davt_compensation_service_relocation")
public class RelocationCompensation extends Compensation<RelocationCompensation> {
#Valid
#ManyToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
#JoinColumn(name = "phone_id")
#ForeignKey(name = "FK_relocationCompensation_phone")
private Phone phone = new Phone();
#Valid
#ManyToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
#JoinColumn(name = "address_id")
#ForeignKey(name = "FK_relocationCompensation_address")
private Address address = new Address();
//rest of properties, setters and getters, equals and hashcode overrides
}

Since this is the only question that comes up you google search this error, I wanted to share another potential solution. I had an issue when my abstract class used Single Table inheritance and gave the 'Cannot instantiate abstract class or interface' exception when I tried to read my pre-loaded data.
My persistence.xml contained the abstract class, but it did not include the classes that extend the abstract class. Since the code to read the classes are not directly referenced they do not throw a invalid entity class exception. When it tried to instantiate the class based on the DiscriminatorColumn value it threw this error. Adding the implementation class to persistence.xml fixed this issue.

My fault was, that I forgot to mark the inherited Entity as such (with #Entity) and so Hibernate had no concrete class to load the data

In my case I was using dbRider to setup H2 with test data and forgot to add some yml files with data, which class that was failing to be initialized depended on.

I had this same issue - I was trying to create an instance of the abstract class rather than the concrete subclass

hibernate HQL - subquery

I have a simple (I guess) problem but I have no idea what's wrong.
I'm trying to execute following HQL query:
String hql = "delete CinemaProgramme program where program.id in (select q.id from CinemaProgramme q left join q.timetable a " +
"where a > :today)";
and I get an error:

However, when I just try to execute the query without the delete:
String hql = "from CinemaProgramme program where program.id in (select q.id from CinemaProgramme q left join q.timetable a " +
"where a > :today)";
Then it works fine....
Subquery itself also works correctly:
String hql = "select q.id from CinemaProgramme q left join q.timetable a " +
"where a > :today)"
........
#Entity
#Table(name = "cinema_programme")
public class CinemaProgramme implements Serializable {
#Id
#GeneratedValue(strategy = IDENTITY)
#Column(name = "id", unique = true, nullable = false)
private int id;
#ElementCollection
#LazyCollection(LazyCollectionOption.FALSE)
#JoinColumn(name = "programme_id")
private List<Date> timetable;
#ManyToOne(cascade= CascadeType.ALL,fetch = FetchType.EAGER)
#JoinColumn(name = "movie_id")
private Movie movie;
}
Any ideas?
PS.
delete from CinemaProgramme AS program - also doesn't work

There are not enough details about the entities. Does this work:
delete CinemaProgramme where id in (select q.id from CinemaProgramme q left join q.timetable a where a > :today)
OR
delete CinemaProgramme where timetable > :today

from the inormation given i can find out below
#GeneratedValue(strategy = GenerationType.AUTO) is missing for id field in Role entity. Though i think auto is default value.But still its worth to cross check.
As error clearly says its unique key constraint voilation. My guess is there is some check constraint defined in defined in your DB. Duplicate values are allowed for foreign keys.
