I am new to hibernate framework. i made a sample project just to test hibernate. i set up the project. but when i run it i got this error
org.hibernate.HibernateException: /hibernate.cfg.xml not found
at org.hibernate.util.ConfigHelper.getResourceAsStream(ConfigHelper.java:147)
at org.hibernate.cfg.Configuration.getConfigurationInputStream(Configuration.java:1405)

at org.hibernate.cfg.Configuration.configure(Configuration.java:1414)
at org.hibernate.cfg.AnnotationConfiguration.configure(AnnotationConfiguration.java:966)
The Hibernate.cfg.xml file that i put in the main package of the project.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

I am using netbeans 7.0
As per DTD, <hibernate-configuration> should have a single <session-factory> but you have declared it twice.
Regarding second error:
org.hibernate.HibernateException: /hibernate.cfg.xml not found
Hibernate looks for the configuration file at the root of the classpath, so check if you have placed this file at root of your classpath.
So once you build your project the hibernate.cfg.xml file should be in classes directory.
Add the following in first line of your xml:
<?xml version="1.0" encoding="UTF-8"?>

This is the cfg file:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC

The error:

Does anybody know how could I fix this error? I tried different
paths for the hbm xml file , i even tried to move it same place
with the cfg file but it still doesnt work, I am a newbie and dont
really know much about it, I tried to follow some tutorials but I
still cannot manage to make it work.
Thank you!
This is the project:

I'm trying to integrate Hibernate in my project but I receive this error:
Using GlassFish for my app server.
javax.xml.bind.JAXBException: ClassCastException: attempting to cast
bundle://2.0:1/javax/xml/bind/JAXBContext.class to
jar:file:/Users/.../glassfish3/glassfish/modules/endorsed/jaxb-api-osgi.jar!/javax/xml/bind/JAXBContext.class.
Please make sure that you are specifying the proper ClassLoader.
Below is my hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>

When I run my program I get this error:
Error: Could not find or load main class
org.hibernate.dialect.DB2390Dialect
I have checked all the jar files required are in place. Please help. I guess there is problem with the hibernate configuration file. Find the configuration file below:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<property name="hibernate.connection.username">batch</property>

<property name="hibernate.show_sql">true</property>
<property name="hibernate.hbm2ddl.auto">none</property>
<mapping resource="galaxe.model.Network" />
</session-factory>
</hibernate-configuration>
In configuration you need to mention for DB2390 as below
property name="hibernate.dialect" value="org.hibernate.dialect.DB2390Dialect"
if you use oracle, it will be different
property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect">
I followed this tutorial: http://manikandanmv.wordpress.com/2011/04/13/hibernate-basics-simple-example/
This is my file structure

When I run Java Applet, I get this error
Initial SessionFactory creation failed.org.hibernate.MappingNotFoundException: resource: src/com/bookstore/bookapp.hbm.xml not found
However, I have that file there as you can see it. When I put the file under
workspace-windows\226project1\src\com\bookstore
I'm still facing this error even then, Can someone help?
This is my hibernate.cfg.xml

Move your mapping files into src/main/resources. Only .java files belong in src/main/java.
There is an example project on github showing how to correctly reference XML mapping files from a hibernate.cfg.xml. Please refer to https://github.com/zzantozz/testbed/tree/master/hibernate-with-xml-mappings
I'm using Tomcat server, I started it yesterday morning and it continuously runs until this morning, but when I tried to login in my application it shows:
org.hibernate.TransactionException: JDBC rollback failed
What is the problem - is any persistent session here or is sessionfactory null?
I got the problem ,
ie i attached a different jar named c3p0-0.9.1.jar file and add some lines in hibernate-cfg.xml file
The code is :
<?xml version="1.0" encoding="UTF-8"?>
