Ubuntu-16.04 - Hibernate5.2 - PostgreSql9.5 Password Authentication Issue

I am using PostgreSql for the first time and stuck with connection authentication problem. I have created a new user "hibernate" with password and able to make connection through Squirrel SQL client. However when I use the same username and password in Hibernate, it fails stating that authentication failed for my "desktop username" (Yes. somewhere my local user name gets in and I am not able to figure out.
Can someone tell me what could be wrong with my PostgreSQL configuration ?

Hibernate: Connection to DB2 database fails (dialect?)

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:

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.

JPA, HIBERNATE strange error

i dont know why im getting this error, i tryed a lot of different persistence.xml configs over the internet, but the error never change...
and in my classpath i have all the .jars from required folder from this hibernate download ( http://hibernate.org/orm/) and i downloaded the validator, i have everything in WebContent/web-inf/libs and the hibernate.xml is in the src/meta-inf....

Hibernate MappingException in java

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.

Hibernate auto-generated code reporting successful persist but no new records in DB found

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.
