persistence jsonb field to h2 using hibernate

source code
I want to use jsonb column type. When I used postgresql there is no problem. But when I use H2 I can not persist my entity. Native sql works but when saving EntityManager.persist i got below error
ERROR: Data conversion error converting "X'aced000574000f7b226b6579223a2276616c7565227d' (json_entities: ""attributes"" ""JSONB"")"; SQL statement:

I read lots of forms but the suggested solution does not work for me. I also debug the H2 source code and see that ValueJson.convertToJson throw exception because of value type not handle on switch case. Look at the source code of org.h2.value.Value.java
private ValueJson convertToJson() {
switch (getValueType()) {
case BOOLEAN:
return ValueJson.get(getBoolean());
case BYTE:
case SHORT:
case INT:
return ValueJson.get(getInt());
case LONG:
return ValueJson.get(getLong());
case FLOAT:
case DOUBLE:
case DECIMAL:
return ValueJson.get(getBigDecimal());
case BYTES:
case BLOB:
return ValueJson.fromJson(getBytesNoCopy());
case STRING:
case STRING_IGNORECASE:
case STRING_FIXED:
case CLOB:
return ValueJson.get(getString());
case GEOMETRY: {
ValueGeometry vg = (ValueGeometry) this;
return ValueJson.getInternal(GeoJsonUtils.ewkbToGeoJson(vg.getBytesNoCopy(), vg.getDimensionSystem()));
}
default:
throw getDataConversionError(Value.JSON);
}
}
getValueType return 19 which means JAVA_OBJECT. How can I handle this problem?

I'm using Spring Boot with Liquibase and this library (https://github.com/vladmihalcea/hibernate-types) to accomplish this. And this article to accomplish this https://vladmihalcea.com/how-to-map-json-objects-using-generic-hibernate-types/.
The first step is have a Liquibase change set that only runs in test mode to treat JSONB column types as JSON. H2 supports the latter but not the former.
This is the first change set that runs, and it is only targeted if the context is test and if the target DB is H2.
<changeSet id="0" author="psc" context="test" dbms="h2">
<sql>
CREATE TYPE IF NOT EXISTS "JSONB" as json;
</sql>
</changeSet>
Contents of application-test.properties
spring.liquibase.contexts=test
My test entity. See How to map json article to better understand the annotations that were used.

#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
private String name;

Example of a test that exercises the JSON column. I'm making use of Spring Boot's DataJPATest test slice feature.

public class CustomerServiceH2Test {
#Autowired
private CustomerRepository customerRepository;
#Test
public void testFindAll() {
Customer customer = Customer.builder()
.name("Phil Calouche")
.customerDetails(CustomerData.builder().x("x-value").build())
.build();
customerRepository.save(customer);
assertThat(customerRepository.findAll()).hasSize(4);
}
}

And it is main class

import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
/**

public class JavaApplication11 {
/**

public static void main(String[] args) {
// TODO code application logic here
EntityManagerFactory emf = Persistence.createEntityManagerFactory("JavaApplication11PU");
EntityManager em = emf.createEntityManager();
em.getTransaction().begin();
NewEntity x = new NewEntity();
x.setName("anan");
em.persist(x);
em.getTransaction().commit();
em.close();
emf.close();
}
}
Lastly it is my persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

</persistence>

Is this the whole code?
Because the end of stack trace points to JavaApplication11.java:29, which is } sign of your main, which is weird.

Why can't I query an entity with a TYPE-WHERE clause matching the entity type in JPA 2.1?

Queries in the form of an entity class A in the form of
SELECT a from A a WHERE TYPE(a) = A
fail with
could not resolve property: class of: de.richtercloud.type.operator.nonsense.A [SELECT a from de.richtercloud.type.operator.nonsense.A a WHERE TYPE(a) = A]
which I don't understand because restricting A to A should exclude all superclass instances which aren't As as well as subclass instances.
Example:
package de.richtercloud.type.operator.nonsense;
import java.io.File;
import java.sql.SQLException;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.persistence.EntityManager;

import javax.persistence.Query;
/**

* #author richter
*/
public class NewMain {
private final static File DATABASE_DIR = new File("/tmp/type-operator-nonsense");
private final static String DERBY_CONNECTION_URL = String.format("jdbc:derby:%s", DATABASE_DIR.getAbsolutePath());
/**
* #param args the command line arguments
*/
public static void main(String[] args) throws SQLException {
//setup database
EntityManagerFactory entityManagerFactory = null;
try {
Map<Object, Object> entityManagerFactoryMap = new HashMap<>();
entityManagerFactoryMap.put("javax.persistence.jdbc.url",
String.format("%s;create=%s", DERBY_CONNECTION_URL, !DATABASE_DIR.exists()));
entityManagerFactory = Persistence.createEntityManagerFactory("type-operator-nonsense",
entityManagerFactoryMap);
//show issue
EntityManager entityManager = entityManagerFactory.createEntityManager();
A a = new A(1L, "b");
entityManager.getTransaction().begin();
entityManager.persist(a);
entityManager.flush();
Query query = entityManager.createQuery("SELECT a from A a WHERE TYPE(a) = A");
List<?> queryResult = query.getResultList();
entityManager.getTransaction().commit();
System.out.println(queryResult.size());
}finally {
if(entityManagerFactory != null) {
entityManagerFactory.close();
}
}
}
}
persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>

</properties>
</persistence-unit>
</persistence>
with org.hibernate:hibernate-entitymanager:5.1.0.Final and org.apache.derby:derby:10.11.1.1
A is a POJO in this example which doesn't involve inheritance, that shouldn't matter for the restriction I expect (although it wouldn't make sense to apply it if there's no inheritance):
package de.richtercloud.type.operator.nonsense;
import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.Id;
#Entity
public class A implements Serializable {
private static final long serialVersionUID = 1L;
private String b;
#Id
private Long id;
public A() {
}
public A(Long id, String b) {
this.id = id;
this.b = b;
}
public void setB(String b) {
this.b = b;
}
public String getB() {
return b;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}

This behaviour occurs due to a hibernate bug https://hibernate.atlassian.net/browse/HHH-10653. The example above works fine with OpenJPA.

TYPE() can only be used in inheritance mapping.
Is A a class in a inheritance mapping and A either the route class with #Inheritance or A extends a class that has #Inheritance declared?
Example.
#Inheritance
#Entity
public class Project
#Entity
public class DesignProject extends Project
#Entity
public class QualityProject extends Project
#Entity
public class SoftwareProject extends Project
Now you can use TYPE()
SELECT p
FROM Project p
WHERE TYPE(p) = DesignProject OR TYPE(p) = QualityProject

The module has not been deployed [netbeans+glassfish]

i am developping a project base on J2EE EJB JSF, database is MYsql, the project works very well last week. but today, it can't be deployed when i run it. here are some exception:

Thanks in advance.

As indicated by the following exception stacktrace
Exception Description: Error encountered when building the #NamedQuery [Adresse.maxId] from entity class [class org.eclipse.persistence.internal.jpa.metadata.queries.NamedQueryMetadata].
the problem is here :
#NamedQuery(name = "Adresse.maxId", query = "SELECT max(idAdresse) FROM Adresse"),
To solve the problem, try this instead:
#NamedQuery(name = "Adresse.maxId", query = "SELECT max(a.idAdresse) FROM Adresse a"),

Try out these steps:
Undeploy the application from glassfish server.
Restart the glassfish server.
Restart netbeans.
Again deploy your application on the glassfish server.

Try to remove adresseManager = new AdresseManager(); from your AdresseMBean class.
#EJB injects and creates already the object.
Then try to redeploy the project and put a debug breakpoint in getAdresses method to see if adresseManager object isn't null or do a poor Sysout.
If you want to initialize services on starting of a managed bean, you'll need to use #PostConstruct annotation on a custom public method inside managed bean and code your initialisation there (eg. loading entity list from db).
Hope it will help you.
PS : Excuse my mistakes for english language, i'm French.
PS2 : I've not seen that it was working before, so it is perhaps a deployment problem !
