I started using Hibernate today and tested a simple example but I'm getting the error: hibernate.cfg.xml not found.
I putted the hibernate.cfg.xml file in the src folder and here is its content:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd" >

<property name="hbm2ddl.auto">update</property>
<mapping resource="com/mycompany/model/Product.hbm.xml"/>
</session-factory>
</hibernate-configuration>
And I putted the HibernateUtil.java file under util folder (src/util) and here is its content
package util;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class HibernateUtil
{
private static final SessionFactory sessionFactory = buildSessionFactory();
private static SessionFactory buildSessionFactory()
{
try
{
// Create the SessionFactory from hibernate.cfg.xml
return new Configuration().configure("hibernate.cgf.xml").buildSessionFactory();
}
catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
public static void shutdown() {
// Close caches and connection pools
getSessionFactory().close();
}
}
I also have the Jars added to the build path.
My class Test.java :
import ...
public class Test {
public static void main(String[] args) {
// TODO Auto-generated method stub
ProductDao pd = new ProductDao();
try {
Product p = new Product("PC", 1000L);
pd.add(p);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
The add method :
public void add(Product p) {
Session session = HibernateUtil.getSessionFactory().openSession();
Transaction tx = session.beginTransaction();
session.beginTransaction();
session.save(p);
tx.commit();
}
Thanks in advance
If using maven try putting it in
/src/main/resources
If using simple eclipse project (without maven), put it in project root directory (not in the src)
Also you misspelled the name of the file in the source
return new Configuration().configure("hibernate.cgf.xml").buildSessionFactory();
it must be
hibernate.cfg.xml
If its a Maven project just add cfg.xml file in /src/main/resources in eclips

I have a spring boot project. I put in my resource folder hibernate.cfg.xml file.
this is my hibernate.cfg.xml file:

I have a hibernateUtil class used to instantiate a hibernate session.
public class HibernateUtil
{
private static final SessionFactory sessionFactory = buildSessionFactory();
private static SessionFactory buildSessionFactory()
{
try
{
// Create the SessionFactory from hibernate.cfg.xml
// return new Configuration().configure().buildSessionFactory();
return new AnnotationConfiguration().configure().buildSessionFactory();

In my application controller I have an endpoint in which I am requesting my mysql database.
#RequestMapping("/getbuildinginfo/{buildingid}")
public void getbuildinginfo(String buildingid)
Session session = null;
session = HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
String query = "select * from exportbatch.exportbatch";
SQLQuery sqlQuery = session.createSQLQuery(query);
List<Object[]> rows = sqlQuery.list();
HibernateUtil.shutdown();
This works fine the first time I run the project, but if I call the endpoint a second time, I am getting this exception:
org.hibernate.service.UnknownServiceException: Unknown service requested [org.hibernate.engine.jdbc.connections.spi.ConnectionProvider]
Could someone help me with this ? why it works the first time? Is it a spring boot context problem? if yes how could I resolve it ?

If you are using spring then, Add autowire on sessionfactory or get it from application context. You can use following code
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
public class ApplicationContextProvider implements ApplicationContextAware{
private static ApplicationContext context;
public static ApplicationContext getApplicationContext() {
return context;
}
#Override
public void setApplicationContext(ApplicationContext ac)
throws BeansException {
context = ac;
}
}
You can use this class anywhere in your code like
ApplicationContextProvider.getApplicationContext().getBean("sessionFactory");
Please try the following code for creating sessionfactory
final StandardServiceRegistry registry = new StandardServiceRegistryBuilder().configure() // configures settings from hibernate.cfg.xml
.build();
try {
sessionFactory = new MetadataSources( registry).buildMetadata().buildSessionFactory();
}
catch (Exception e) {
StandardServiceRegistryBuilder.destroy( registry );
}
Hope this helps.
I have a problem with a query in HQL also my SQL base has some databases , so need to put together a query that take this table at the bottom, my sql base always starts in database 'database' and I must refer to the database webproduction then so I wrote my query :
#Entity
#Table(name="File")
#NamedQueries(
{
#NamedQuery(name="file.allList",
query = "use webproduction select * from File")
}
)
My Config:
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
<property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>

<property name="hibernate.show_sql">true</property>
<property name="hibernate.format_sql">true</property>
<!-- <mapping class="entity.Sell" /> -->

My Class hibernate:
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
try {
sessionFactory = new AnnotationConfiguration().configure(
"config/sql_hibernate.cfg.xml").buildSessionFactory();
} catch (Throwable ex) {
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
My method:
public List<File> getFile() throws Exception{
session = HibernateUtil.getSessionFactory().openSession();
query = session.getNamedQuery("file.allList");
List<File> list1 = query.list();
session.close();
return list1;
}
For SQL server you would remove the 'use webproduction' from your named query and use:
jdbc:sqlserver://10.11.1.05;DatabaseName=webproduction
as your hibernate.connection.url
see http://www.java2s.com/Tutorial/Java/0340__Database/AListofJDBCDriversconnectionstringdrivername.htm
Can anybody help me solve this situation?
I have a Tomcat and simple JSF Application: https://github.com/gooamoko/jsfbilling/.
When I run application on Tomcat, it runs normally, but after several requests (for example 10 quick refresh page) raise the exception can't open connection.
I think, it's normal, but where is the mistake?

How and where should I correct close open connections?
Thanks for wasting your time for me.
I've read Hibernate documentation and found example of HibernateUtil class.
After comparing with my HibernateProvider I found, that seems like in my HibernateProvider Factory was build every call of getSessionFactory(). New version of HibernateProvider is
package ru.gooamoko.dao;
import org.hibernate.HibernateException;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
public class HibernateProvider {
private static final SessionFactory factory = buildFactory();
public static SessionFactory getSessionFactory() {
return factory;
}
private static SessionFactory buildFactory() {
try {
Configuration configuration = new Configuration();
configuration.configure();
ServiceRegistry registry = new StandardServiceRegistryBuilder().applySettings(
configuration.getProperties()).build();
return configuration.buildSessionFactory(registry);
} catch (HibernateException ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
}
So, now query
SELECT COUNT(*) FROm pg_stat_activity;
returns 6, one of which is psql client. Even after minute of re-requesting page. I think, it's a progress.
The only one thing remains - is to make possible for Hibernate work with postgresql-jdbc.jat in Tomcat /lib folder and no use jar in WEB-INF/lib. I read that placing postgresql-jdbc.jar into WEB-INF/lib may cause memory leaks.
P.S. I also read, that Hibernate should automaticaly close connections when session commits or rollback and I don't need to close connections explicitly.
Thanks for your suggestions, cos I always need someone who keep my eyes open.
I'm new to Hibernate. Using Hibernate 3.0 from Eclipse indigo.
The topic is discussed here and the answer is not helpful, Hibernate: javax.naming.NoInitialContextException (Component Mapping via Annotations)
i.e. I tried removing name from session-factory and still getting the error.
Am I missing something? Can anyone help with this?
The error is as follows:

The DAO file is generated by Hibernate and outline is given as:
public class PatternsHome {
private static final Log log = LogFactory.getLog(PatternsHome.class);
private final SessionFactory sessionFactory = getSessionFactory();
protected SessionFactory getSessionFactory() {
try {
return (SessionFactory) new InitialContext()
.lookup("SessionFactory");
} catch (Exception e) {
log.error("Could not locate SessionFactory in JNDI", e);
throw new IllegalStateException(
"Could not locate SessionFactory in JNDI");
}
}
.....
}
I'm not able to make this work on a stand alone. But I created a generic DAO with HibernateUtil and created sessionFactory using
sessionFactory = new Configuration().configure(new File("hibernate.cfg.xml")).buildSessionFactory();
and accessed DB in my DAO using
Session session = HibernateUtil.getSessionFactory().openSession();
Transaction transaction = null;
try{
transaction = session.beginTransaction();
session.save(myData);
transaction.commit();
System.out.println("Data is Saved");
}catch(Exception e){
e.printStackTrace();
}finally{
session.close();
}
This worked.
