JPA stackoverflow error when fetching data

I have 2 entities namely Teacher and Club, I need to retrieve the teacher data along with its related club and/or sports.
I a bit new to JPA so am having trouble debugging the stack overflow error I get when I use the findAll method on the Teacher repository.
I had tried adding #JsonIgnore annotation to my one-to-many annotation to deal with the recursion problem as suggested in some similar questions but was still getting problems and am not sure how exactly it's supposed to solve the problem.

this.id = id;

Hibernate search is not working

I am developping a java/jee application in which i am using spring boot and hibernate as frameworks i used hibernate search for full text searching but unfortunately i always got an empty list as result.I am using hibernate version 5.1 and hibernate search orm version 5.5.3.Final.Here is my code :
public void search() {
FullTextEntityManager fullTextEntityManager = Search.getFullTextEntityManager(this.em);
try {
fullTextEntityManager.createIndexer().startAndWait();
// create native Lucene query unsing the query DSL
// alternatively you can write the Lucene query using the Lucene
// query parser
// or the Lucene programmatic API. The Hibernate Search DSL is
// recommended though
QueryBuilder queryBuilder = fullTextEntityManager.getSearchFactory()
.buildQueryBuilder()
.forEntity(Application.class)
.get();
org.apache.lucene.search.Query luceneQuery = queryBuilder.keyword().wildcard().onField("reference").matching("di*")
.createQuery();
// wrap Lucene query in a javax.persistence.Query
javax.persistence.Query jpaQuery = fullTextEntityManager.createFullTextQuery(luceneQuery,
Application.class);
// execute search
List<Application> result = jpaQuery.getResultList();
System.out.println("your result list is "+result);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

I have solved my problem.It was because of subclasses which were not indexed.

Did you make sure your entities are indexed before searching?
If you are using a pre-existing database, or if you initialized your database without using Hibernate ORM APIs (by using SQL directly, or by restoring a dump), your entities are probably not indexed yet.
You should have a look at the mass indexer, which makes it easy to index a lot of entities: https://docs.jboss.org/hibernate/search/5.5/reference/en-US/html_single/#search-batchindex-massindexer

Spring Boot JpaRepository save call doesn't seem to be doing anything

I'm writing a Spring Boot application that uses JpaRepository interfaces. In a service method where I'm attempting to write some objects, calls to two repositories' save() methods don't appear to be doing anything, but are also not throwing any exceptions.
I'm using mysql, with ISAM tables, with MySQL5Dialect.

According to what I've read on the subject, methods annotated with #Transactional should commit once the method returns. When I execute the method, it does in fact print to the log that it's saving. However, I have sql debugging turned on, and it does not print any sql statements when it saves. (it does print sql statements on selects.)
The method has no problems doing the selects above, only the saves in the latter part. No exceptions are thrown, but the data doesn't appear in the tables that the entities are using. The only line that gets printed in the log for each save looks like this:
o.s.t.i.TransactionInterceptor : Completing transaction for [org.springframework.data.jpa.repository.support.SimpleJpaRepository.save]
I'm not sure if this is relevant, but this call is made by the listener class for a jms queue.
My question is, am I missing anything to enable persisting data in this way? From what I've read, #Transactional automatically has readOnly set to true, and my IDE confirms this. Did I miss something important?

For anyone reading this in the future, the root cause of the issue was that the service method call was coming from a message queue receiver class. I'm not sure why. When I moved the call directly to the web service instead of the queue receiver, the insert happened with no issues.

Hibernate #OneToMany fails with "collection is not associated with any session"

Here's the point: I want to load "DeliveryOrderEntity" (code below) from DB (MySQL). It has 1 foreign key with "one-to-many" relationship. It connects "BillsEntity" using billNumber. To make it clear - I have table ORDER with column BILL_NUMBER and table BILL with columns BILL_ID (primary key) and BILL_NUMBER (column, that connects BILL with ORDER).
Here is my code:
DeliveryOrderEntity.java:

As you can see, I have unidirectional OneToMany relationship. The problem is that when i have 2 rows in DELIVERY_ORDER table with the same BILL_NUMBER and I try to get list of orders - it fails with:

Here is the code where i fetch the list:
public List<DeliveryOrderEntity> listOrders() {
List findAllOrders = new ArrayList();
EntityManager entityManager = transactionManager.getEntityManagerFactory().createEntityManager();
try {
entityManager.getTransaction().begin();
findAllOrders = entityManager.createNamedQuery("findAllOrders").getResultList();
} catch (Exception e) {
e.printStackTrace();
} finally {
entityManager.getTransaction().commit();
}
return findAllOrders;
}
Thank you in advance.

Java persistence: named queries. Multiple parameters changes boolean values to int?

I'm an amateur programmer and I'm having trouble with the java eclipse persistence named queries. I have an entity class. In this class I have created named queries. With the ClientInformation.getList I have two parameters. One on active (Boolean) and one on type (int). When I remove either one it works like a charm, but when I try them both it transforms the boolean value to an integer.

Code snip where I call the named query.

EntityManager em = emf.createEntityManager();
em.getTransaction().begin();
List clientList = em.createNamedQuery("ClientInformation.getList")
.setParameter("ciActive", this.inactiveClientSelected)
.setParameter("ciType", this.typeClientSelected)
.getResultList();
clientList_ComboBox.addItem("Kies klant...");
if (clientList.isEmpty() == false) {
for (Object clientList1 : clientList) {
clientList_ComboBox.addItem(clientList1);
}
}
em.close();
emf.close();
This is the message I'm getting.
Call: SELECT CI_NAME FROM CLIENT_INFORMATION WHERE (((CI_ACTIVE = 1)
OR (CI_ACTIVE = 1)) AND ((0 = 0) OR (CI_TYPE = 0))) Internal
Exception: java.sql.SQLSyntaxErrorException: Comparisons between
'BOOLEAN' and 'INTEGER' are not supported. Types must be comparable.
String types must also have matching collation. If collation does not
match, a possible solution is to cast operands to force them to the
default collation (e.g. SELECT tablename FROM sys.systables WHERE
CAST(tablename AS VARCHAR(128)) = 'T1') Query:
ReportQuery(name="ClientInformation.getList"
referenceClass=ClientInformation sql="SELECT CI_NAME FROM
CLIENT_INFORMATION WHERE (((CI_ACTIVE = ?) OR (CI_ACTIVE = ?)) AND ((?

referenceClass=ClientInformation sql="SELECT CI_NAME FROM
CLIENT_INFORMATION WHERE (((CI_ACTIVE = ?) OR (CI_ACTIVE = ?)) AND ((?
= ?) OR (CI_TYPE = ?)))")
Any suggestions or do I need to give more information?
Edit: When I remove the last part from the query ("... AND (:ciType = ...etc) the query works fine, so I think I ruled out the actual parameter passing/ the code passes a boolean. Also, when I remove the first parameter (the Boolean) it works as well. So It's (the combination of) the two parameters.
