Spring and Hibernate upgradation from 4.x to 5.x - java

As part of security upgrade I am trying to upgrade both Spring and hibernate jars to 5.x version due to which I faced many errors. The main issue right now is that my UI screen is blank for all fields.For example there are screens like currency codes,user profile,fee report.Only the field is visible in screen but not the entire page related to it.Could someone please help on this.
Initially there was a main screen which was blank and had error as "Data store implementation not found for Dialect : null"
This got resolved after I edited hibernate.properties file where previously it was,
hibernate.transaction.factory_class =org.hibernate.transaction.JTATransactionFactory
hibernate.transaction.manager_lookup_class=org.hibernate.transaction.JBossTransactionManagerLookup
And I changed it to,
Hibernate.transaction.coordinator_class=jta
Hibernate.transaction.jta.platform=<>
After doing the above change, All the fields in the screen got visible(Basically that screen is the landing page after login which has quick links to other screens)
Now am stuck on what to do to make the rest of screens visible
I am completely new to hibernate and spring and need to work on this as security upgrade so I don't know exactly what is going wrong here..so any help is much appreciated.
My hibernate.properties file

You are getting this error because the persistence.xml file is not built into your WAR file.
This is because you have placed it in the src/main/java directory and it is a Maven project.
Unless you deliberately configure it otherwise (not recommended), Maven only processes .java source files in src/main/java and nothing else.
You must move the META-INF directory and its content from src/main/java to src/main/resources.
Kudos to #Henrique for asking the right question

Facing issue during hot deploy of kar file

My kar file contains the following bundles:
a)common-bundle(contains hibernate as the JPA provider)
b)client-bundle(accesses the entityManagerFactory present inside common-bundle and execute business logic)
I've a strange problem while executing hot deploy of kar file on karaf container.
If I try to do a normal deploy(i.e. by stopping the karaf container,putting the kar file into deploy folder and re-starting karaf container),both the bundles get up and running without any problem.
However,when I try to hot deploy the kar file on karaf container,it throws me the following exception:

Please help.
Apparently every bundle is using a datasource but no one is creating it.
javax.naming.NameNotFoundException: osgi:service/javax.sql.DataSource/"(osgi.jndi.service.name=jdbc/ds)"
You need to create this datasource, for example by dropping a simple XML file into deploy dir:
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="org.postgresql.Driver" />
<property name="url" value="jdbc:postgresql://localhost:5432/yourdb"/>
<property name="username" value="XXX"/>
<property name="password" value="XXX"/>
</bean>
<service interface="javax.sql.DataSource" ref="dataSource">
<service-properties>
<entry key="osgi.jndi.service.name" value="jdbc/ds"/>
</service-properties>
</service>
</blueprint>
You will need jdbc and jndi features installed.

Generic class Implementation for a SpringData & QueryDSL Service

I have a bunch of service classes that have repositories that extends JpaRepository and QueryDslPredicateExecutor.
The methods in the service classes are identical except for the entity that it processes. I am trying to create
a generic service class but I am getting a "Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [pkg.BaseRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency".
Below are my classes:

#NoRepositoryBean
public interface BaseRepository<T> extends JpaRepository<T, Long>, QueryDslPredicateExecutor<T> {}
//RegionRepository.java
#Repository
public interface RegionRepository<Region> extends JpaRepository<Region, Long>, QueryDslPredicateExecutor<Region> {}
//ProvinceRepository.java
#Repository
public interface ProvinceRepository<Province> extends JpaRepository<Province, Long>, QueryDslPredicateExecutor<Province> {}
...
and many more XxxRepository interfaces
//AbstractBaseService.java
public abstract class AbstractBaseService<T>{
#Autowired
private BaseRepository<T> repository;
public void add(T entity) {
System.out.println("Adding entity " + entity.getClass());
}
public T retrieve(Long id) {

Is there a way to make the AbstractBaseService work as I envision above so that I don't have to create the one Service class with the same implementation as AbstractBaseService for each of my entities (Region, Province, User, Vehicle.... etc)?
Any help would be greatly appreciated.
Thanks in advance,
Mario
//RegionRepository.java
#Repository
public interface RegionRepository<Region> extends JpaRepository<Region, Long>, QueryDslPredicateExecutor<Region> {}
^^^^^^ Here you are actually making a new Type Variable, which is bounded to Object.
You are making new Type Variables, this actually hides the class name you are making the Repository for.
I was finally able to make my original post work. What were missing were the annotation #NoRepositoryBean on the BaseRepository.java interface and #Repository annotations on RegionRepository/ProvinceRepository interfaces as edited above.

private String password;
#Id
#NumberFormat(style = Style.NUMBER)
#GeneratedValue(strategy = GenerationType.AUTO)
private int ID;
// getters and setters
That is pretty simple (at least I hope it is ;) ).
There is a classloader hierarchy, so that the classloader that is "above" in the hierarchy cannot load the objects that are lower in the hierarchy, however those that are lower, can load objects above them.
ie.
The EAR classloader is above the WAR classloader. So the classes that are loaded in EAR cannot load objects from WAR. But the WAR objects can load objects from EAR.
I suppose, that since You got the persistence.xml in the EAR, You also put hibernate dependencies in the EAR, and so they cannot load objects from WAR.
If this is true, then I would suggest trying to move hibernate dependencies to WAR and see if it works, or reorganizing Your EAR/WAR with classloader hierarchy in mind :)

No Persistence provider for EntityManager named... error [duplicate]

No Persistence provider for EntityManager named X

Closed 9 years ago.
My persistence xml file is like that
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
version="1.0">
<persistence-unit name="hibernateEbru">

<class>com.hibernate.business_card</class>
<properties>
<property name="hibernate.hbm2ddl.auto" value="create" />
<property name="hibernate.show_sql" value="true" />
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" />
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />

<property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/BusinessDb" />
</properties>
</persistence-unit>
</persistence>
Then I have my code calling it with this:
public class test {
public static void main(String[] args) {
EntityManagerFactory emf = Persistence.createEntityManagerFactory("hibernateEbru");
EntityManager em = emf.createEntityManager();
em.getTransaction().begin();
business_card bc = new business_card();
bc.setName("Ebru");
em.persist(bc);
em.getTransaction().commit();
em.close();
emf.close();
}
}
I got the following error message:
Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named hibernateEbru
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:56)

You will need to move the persistence.xml file to an appropriate location
From JPA spec:
A persistence.xml file defines a persistence unit. The persistence.xml
file is located in the META-INF directory of the root of the
persistence unit.
The root of the persistence unit is the key here.
If you are a non-Java EE app
The jar file or directory whose META-INF directory contains the
persistence.xml file is termed the root of the persistence unit.
If you are in a Java EE app, the following are valid
In Java EE environments, the root of a persistence unit must be one of
the following:
an EJB-JAR file
the WEB-INF/classes directory of a WAR file[80]
a jar file in the WEB-INF/lib directory of a WAR file
a jar file in the EAR library directory
an application client jar file
