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,

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'm using Hibernate 5.2 with JPA 2.1 Library.Every time I want to run my application it doesn't stop - I have to stop it manually because it's still working. Records are being saved to the database correctly. These are my project files:
Main.java
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("testjpa");
EntityManager em = entityManagerFactory.createEntityManager();
em.getTransaction().begin();
Kraj country = new Kraj();
country.setNazwa("ExampleCountry");
em.persist(country);
em.getTransaction().commit();
em.close();
}

i had a same problem after changing the version it works for me.
I'm trying to connect to Informix database using Hibernate 5.2.10, but the program doesn't respond and gets stuck without throwing any error message.
I can't find anything from the console . Any suggest on what mistake I made? I'm new to Hibernate

I did a quick test with 5.2 and the latest jdbc driver and it appears to work fine for me. I'm using your HiberanateUtil and a similar Hibernate config file:

As yours, 'last' INFO message is "Connection obtained from JdbcConnectionAccess" , but after that I'm also getting the nosuchmethod exception. I have to press control+c to get out.
Maybe your exceptions are been sent somewhere else ;)
EDIT
This is the code I'm using to test it directly from the console, should be everything you need to run it.

but I guess it shouldn't be much different than what you already have.
Thanks for trying to help me out. The issue got resolved after I removed this property from hibernate config file.
<property name="hbm2ddl.auto">update</property>
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.

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 have hibernate and I would like to decrease the logging that happens in console everytime it runs. I do not have log4j in my application nor do I want to add it in.

As per your log details I understood that hibernate version is- Hibernate 4.0.4.Final.Since version 4.0, Hibernate has used the JBoss logging library and so even your application does not contain any log4j still hibernate is using JBoss logging provider as default provider.
For more please go through this link:
http://docs.jboss.org/hibernate/orm/4.3/topical/html/logging/Logging.html
Hope this info will help you to understand why logs are still available without any log4j.
You can try to disable all Logger functions using java.util.logging :
private void disableLogging() {
LogManager logManager = LogManager.getLogManager();
Logger logger = logManager.getLogger("");
logger.setLevel(Level.SEVERE); //could be Level.OFF
}
It would affect any other Logger you're using, but in some cases may be useful.
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.
