I have a problem with my hibernate.cfg.xml in IntelliJ IDE.
Here is my hibernate config file:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver:class">org.postgresql.Driver</property>
<property name="connection.url">jdbc:postgresql://localhost/HIndex</property>
<property name="hibernate.connection.username">index_user</property>
<property name="hibernate.connection.password">password</property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL Dialect -->
<property name="hibernate.dialect">org.hibernate.dialect.PostgreSQL82Dialect</property>
<!-- Assume test is the database name -->
<property name="show_sql">true</property>
<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">create</property>
<!-- Names the annotated entity class -->
<mapping class="HIndexSaar.HIndex.Person"/>
<mapping class="HIndexSaar.HIndex.University"/>
<mapping class="HIndexSaar.HIndex.Publication"/>
</session-factory>
</hibernate-configuration>
And this is my application class:
package HIndexSaar.HIndex;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
public class HibernateManager {
private static SessionFactory factory;
public HibernateManager(){
//
//* Setup the configuration.
//
Configuration config = new Configuration().configure("hibernate.cfg.xml").addAnnotatedClass(Person.class) .addAnnotatedClass(University.class).addAnnotatedClass(Publication.class);
factory = config.buildSessionFactory();
}
I get an error by running the following code:
package HIndexSaar.HIndex;
public class AppHibernate {
public static void main(String[] args){
HibernateManager mng = new HibernateManager();
[...]
}
}
So something seems to be broken in building the SessionFactory in the HibernateManager. I get the error
Could not locate cfg.xml resource
and the following stacktrace:

I already have placed the hibernate.cfg.xml file under /src/main/java/resources but obviously something goes still wrong.
Does somebody have an idea what could be the mistake I made? Surprisingly, the same code runs in Eclipse without error, so what could be the problem of IntelliJ? I use the same SDK/JDK, namely jdk 1.7.
If your are using intellij then try to create new module with hibernate framework support then paste this same code and execute it.
This might be path difference in clipse and intellij

Im trying to configure a simple JPA project and I'm very stuck.
I have a working dataSource (MySQL) & GlassFish with multiple tables.
I did the following steps (all of the files generated by Intellij):
Create new project with Java EE Persistance with Hibernate Provider.
Import DB that has a Student table.
Generate Entity classes with Intellij IDE.
Import Hibernate-entitymanager library from Maven.
Import MySQL connector.
Try to run a simple JPA program to create new row but I get an exeption :
No Persistence provider for EntityManager named persistenceUnit
What can be the problem? I tried almost every tutorial and every question here but with no success!
Please Help me!
(sometimes the Hibernate in the persistance provider is colored red)

I have followed intellij instruction but i can not find any solution. Please help
It is not an error. It is just an information that you don't have hibernate.properties file in the class path. You have properties in the hibernate.cfg.xml, it is ok too. But you need to specify hibernate.dialect, hibernate.connection.username and hibernate.connection.password.
And if you don't have tables in the database you need this too
<property name="hbm2ddl.auto">update</property>

I believe it is an issue with this line in your xml configuration.
<!-- Mapping files -->
<mapping class="com.secure.eps.model.User"/>
Refer to hibernate docs: http://www.tutorialspoint.com/hibernate/hibernate_mapping_files.htm.
I would like to know how to create a JNDI entry for a MySQL database using Eclipse Kepler and Tomcat 7 (Is there a plugin for Eclipse?).
When I created the Dynamic Web Project using Eclipse, I did NOT checked the "Generate web.xml deployment descriptor", so, I do not have a web.xml file in my project.
The JDNI resource definition is declared in Tomcat's <Context> element in context.xml 1, not your new application's web.xml. So whether it's generated or not, it doesn't actually matter.
<Context>
<Resource name="jdbc/YourDB" auth="Container"
type="javax.sql.DataSource"
username="username" password="password"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://dbserver:dbport/actualDbname"/>
</Context>
If you had web.xml in your application, you will need an entry like this to refer to the datasource mentioned above:
<resource-ref>
<res-ref-name>jdbc/YourDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
Since you opted not to have web.xml, you can use annotations:
#Resource(lookup = "java:comp/env/jdbc/YourDB")
private DataSource dataSource;
1 There are multiple ways to define the Context, refer to Tomcat's definition on Defining a Context.
When I posted the question, I forgot to say that I'm using Hibernate and to include the files.
The hibernate.cfg.xml is:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE
hibernate-configuration
PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

There is an Hibernate util class:
package hibernateUtil;
import javax.annotation.Resource;
import org.hibernate.*;
import org.hibernate.cfg.*;
#Resource(lookup="java:comp/env/jdbc/exemplosweb")
#SuppressWarnings("deprecation")
public class HibernateUtil

private static final SessionFactory sessionFactory;
static
{
try
{
// Create the SessionFactory from hibernate.cfg.xml
sessionFactory = new Configuration().configure().buildSessionFactory();
}
catch (HibernateException e)
{
// Make sure you log the exception, as it might be swallowed
e.printStackTrace();
throw new ExceptionInInitializerError(e);
}
catch (NoClassDefFoundError e)
{
e.printStackTrace();
throw new NoClassDefFoundError("static HibernateUtil");
}
}
public static SessionFactory getSessionFactory()
{
return sessionFactory;
}
}
and I got this exception:

we are integrating the java blazeds hibernate with flex project..First we tested the pure java hibernate in eclipse and it is executing fine. But when we put the same in tomcat for flex integration with blazeds it is showing the following error.this is the only error.

this is hiberutil.java

why the error is showing? the control is coming from flex side and executing the starting point of the java method...but when it comes to hibernate stuff execution, it is showing this error in tomcat...
But when i execute java+hibernate as a pure java application it is executing fine..
can anybody help me?
Thanks
EDIT 1 After the modification suggested by #Andremoniy and putting the .cfg.xml in src folder and here also in eclipse it is working but not in tomcat with flex
following error comes

I guess the problem is with the code for configuration you mentioned for .hbm.xml may not be working in Tomcat.
I think it needs AnnotationConfiguration object. I guess you used this code due to the Annotationconfiguration object creation is not working.
Better create a maven hibernate project with pom and export the war file to Tomcat (with the changes of Annotationconfiguration). Also use log4j jar for showing the details of Tomcat execution with the debug outputs, so that Tomcat output will print all of execution flow.
It seems to me, that you can solve this problem, by passing hibernate.cfg.xml directly into Configuration.
try (InputStream in = HibernateUtil.class.getResourceAsStream("/hibernate.cfg.xml")) {
Configuration configuration = new Configuration().addInputStream(in).configure();
...
} ...
The only thing, you have to properly point the path or class, for getResourceAsStream. Or you may be want to create InputStream using some relative path.
I have faced the same problem but I found the solution here..
http://www.mkyong.com/hibernate/hibernate-error-an-annotationconfiguration-instance-is-required-to-use/
ie. Change the line:
new Configuration().configure().buildSessionFactory();
to:
new AnnotationConfiguration().configure().buildSessionFactory();
if it is appeared that you use Intellij Idea you need to put hibernate.cfg.xml file into resources folder
and if you will have after next error:
org.hibernate.service.jndi.JndiException: Error parsing JNDI name []
delete in hibernate.cfg.xml file name of tag see picture:
