I am new in Hibernate and Maven. I want to use hibernateOGM. I can successfully build my code but if I run it I see these Information:

my hibernate.cfg.xml and hbm.xml are located in src/main/resources . How can I solve this problem
Did you try placing hibernate.cfg.xml in src/main/resources/META-INF ?
As per your comments you are using
OgmConfiguration cfgogm=new OgmConfiguration();
SessionFactory sessionfactory= cfgogm.buildSessionFactory();
try changing it to:
SessionFactory sessionfactory= new AnnotationConfiguration().configure().buildSessionFactory();

I have a Spring Boot application which was running fine. I just added another column in table and specified it in entity. Now I am running it and the application getting stuck at one point and not starting. It seems to be a Hibernate issue with Spring Boot. Following are the logs:

I am new in hibernate
I have a UserDAO class and a method to determine whether user exists in a specific table or not.
This is my users table in hb3 database:
And this is my class:
public static void main(String[] args) {
System.out.println(userExistsinDB("ABC"));
}
public static boolean userExistsinDB(String username) {
String queryStr = "Select * from users where username=" + username; // since username is unique
SessionFactory sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
Query query = session.createSQLQuery(queryStr);
System.out.println(query.getFirstResult());
session.getTransaction().commit();
session.close();
sessionFactory.close();
return false;
}
But the result is null in query.getFirstResult() , Why?
I have ABC username in users table.
Hibernate config file:
<?xml version="1.0" encoding="UTF-8"?>

Try this:
org.hibernate.Query query = session.createQuery("from users where username = :username");
query.setParameter("username", username);
query.uniqueResult();
You should use parameterized query. It returns null because string literals should be enclosed by quote notation.
I am desperate trying to connect to a DB2 database via hibernate. Problem is here, I know, where the error comes from but I can't solve it or rather don't understand it. Maybe you can help me fix this problem. I would be very grateful!
The following code shows my hibernate.cfg.xml:
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.DB2Dialect</property>
<property name="hibernate.connection.driver_class">com.ibm.db2.jcc.DB2Driver</property>
<property name="hibernate.connection.url">jdbc:db2://db2.example.com:50001/databasename</property>
<property name="hibernate.connection.username">mydbuser</property>
<property name="hibernate.connection.password">mydbpass</property>
<property name="hibernate.connection.pool_size">10</property>
<property name="show_sql">true</property>
<property name="hibernate.current_session_context_class">thread</property>
<mapping class="media.definitions.Product" />
</session-factory>
</hibernate-configuration>
This following code is a class which I've built by a tutorial:
package media.frontend;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
Configuration cfg = new Configuration().configure("hibernate.cfg.xml");
StandardServiceRegistryBuilder sb = new StandardServiceRegistryBuilder();
sb.applySettings(cfg.getProperties());
StandardServiceRegistry standardServiceRegistry = sb.build();
sessionFactory = cfg.buildSessionFactory(standardServiceRegistry);
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
And the following error comes immediately when I start the program (which only tries to catch information of a single column). I've pasted the whole output:

Thanks in advance for your help!
Greets,
Luke
I was facing similar issue in my code. Then i tried updating the recent versions of DB2 jars into my server and the code started working. Try to update your DB2 jar.
I am curious about this error
org.hibernate.MappingException: Unknown entity: xyz
I am new to hibernate. Any suggestions are welcome. Thanks in advance.
Hibernate maps your DB tables to the classes in your project that you have created. In order to load and update values in the DB using these classes, you need to tell Hibernate wich class is mapped to which table. This is where the hibernate configuration file and the Hibernate mapping file comes into picture.
Mapping can be done using annotations or with with a mapping file and include the mapping file name in the hibernate config file.
Read here for more information about these initial steps to setup your environment before you start running your project.
I think you might be trying to store/load an object of class xyz which is not properly mapped with #Entity annotation. Any class that you want to use with Hibernate should be mapped either with annotations or using an XML descriptor.
Other possibility is that your mapping is correct, but you didn't neither explicitly list xyz in hibernate.cfg.xml file nor enabled autodetection of entities.
And as mentioned above, without seeing some actual code it's really hard to give an definitive answer.
Put #Entity in your class.
#Entity
#Table(name="tableName")
public class XYZ {
}
you need to check mappings if using hbm files then check you have included then in config file.and if using annotations then check if you have placed correct annotation type. More details required to provide exact solution.

I have some auto-generated hibernate DAO code which was generated by Eclipse-hibernate reverse engineering plugin.
The EntityManager object's 'persist' method is not throwing any exception but the object is not persisted to the database. Currently the database is table is empty (no records).
I get the following output, any ideas?

persist successful
As well, here is a code snip, I am manually creating a 'Pokemons' object and passing it into the 'persist(..)' method here.
#PersistenceContext private EntityManager entityManager;
private void initManager()
{
if(entityManager != null)
return;
EntityManagerFactory factory;
factory = Persistence.createEntityManagerFactory("manager1");
entityManager = factory.createEntityManager();
}
public void persist(Pokemons transientInstance) {
if(entityManager == null)
initManager();
log.debug("persisting Pokemons instance");
try {
entityManager.persist(transientInstance);
System.out.println("persist successful");
log.debug("persist successful");
}
catch (RuntimeException re) {
log.error("persist failed", re);
throw re;
}
}
em.commit()
For performance reasons, when you call em.persist(), Hibernate persists object to the underlying model, but does not actually execute database instruction until you commit the transaction.
