org.hibernate.internal.util.config.ConfigurationException: Could not locate cfg.xml resource [/HibernateTest/src/hibernate.cfg.xml]
Solution 1
If you have your hibernate.cfg.xml
in the root of the source folder, just do
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
If it is in the package, for an example in the org.nitish.caller
, specify path by this way
SessionFactory sessionFactory = new Configuration()
.configure("/org/nitish/caller/hibernate.cfg.xml").buildSessionFactory();
You need to close the session
(in the finally
block). Don't forget to add rollback
code.
Please, add @Table
annotation to the UserDetails
.
Update
The reason of the error that Hibernate can't find org.postgresql.Driver
class. It resides in postgresql jar. You have that jar at your image, but may be you don't add it to the classpath. Refer How to Add JARs to Project Build Paths in Eclipse (Java).
To close a session
in the finally
block you need to have session
variable outside the try
block.
Session session = sessionFactory.openSession();
try{
} finally {
session.close();
}
Solution 2
I fixed this by moving my config file to src/main/resources
. This is the standard directory for configuration files like hibernate.cfg.xml or hibernate.properties or application related properties files.
Solution 3
new Configuration().configure(new File("hibernate.cfg.xml")).buildSessionFactory());
This solved the error for me!
Solution 4
new Configuration().configure()
takes hibernate.cfg.xml
from root of class path directory. new Configuration().configure("/com/company/project/hibernate.cfg.xml")
takes from root of class path + com/company/project/hibernate.cfg.xml.
If you are using different file name for hibernate configuration from root of class path, then eg: new Configuration().configure("/database.cfg.xml")
If you want to give the full system path of the configuration file then new Configuration().configure(new File("/home/visruth/config/hibernate.cfg.xml))
which takes the configuration file from the given exact location.
Solution 5
All the previous answers are perfect. However, if u need a really quick solution then I would recommend you to just put your hibernate.cfg.xml file in your source folder and write
SessionFactory sessionFactory = new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();
This is simple and works!

I am trying to connect to Postgresql9.1 in ubuntu with pgadmin3. My Pgadmin3 GUI tool does not give any option to create tables by right clicking the database, but it is available in some videos I saw. Therefore, I used terminal to create the database and it showed up in pgadmin3.
My Userdetails file
package org.nitish.hiber; import javax.persistence.Entity; import javax.persistence.Id; @Entity public class UserDetails { @Id private int userId; private String userName; public int getUserId() { return userId; } public void setUserId(int userId) { this.userId = userId; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } }
My HibernateCaller file
package org.nitish.caller; import org.hibernate.HibernateException; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration; import org.nitish.hiber.UserDetails; public class HibernateTest { public static void main(String[] args) { UserDetails user = new UserDetails(); user.setUserId(1); user.setUserName("First User"); try { SessionFactory sessionFactory = new Configuration().configure("/HibernateTest/src/hibernate.cfg.xml").buildSessionFactory(); Session session = sessionFactory.openSession(); session.beginTransaction(); session.save(user); session.getTransaction().commit(); } catch(HibernateException e) { e.printStackTrace(); } } }
Hibernate.cfg.xml
<?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"> <!-- ~ Hibernate, Relational Persistence for Idiomatic Java ~ ~ License: GNU Lesser General Public License (LGPL), version 2.1 or later. ~ See the lgpl.txt file in the root directory or <http://www.gnu.org/licenses/lgpl-2.1.html>. --> <hibernate-configuration> <session-factory> <!-- Database connection settings --> <property name="connection.driver_class">org.postgresql.Driver </property> <property name="connection.url">jdbc:postgresql://localhost:5432/hiber</property> <property name="connection.username">nitish</property> <property name="connection.password"></property> <!-- JDBC connection pool (use the built-in) --> <property name="connection.pool_size">1</property> <!-- SQL dialect --> <property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property> <!-- Enable Hibernate's automatic session context management --> <property name="current_session_context_class">thread</property> <!-- Disable the second-level cache --> <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property> <!-- Echo all executed SQL to stdout --> <property name="show_sql">true</property> <!-- Drop and re-create the database schema on startup --> <property name="hbm2ddl.auto">create</property> <mapping class="org.nitish.hiber.UserDetails"/> </session-factory> </hibernate-configuration>
I am getting following error
Mar 1, 2016 9:02:48 AM org.hibernate.cfg.Environment <clinit> INFO: HHH000206: hibernate.properties not found Mar 1, 2016 9:02:48 AM org.hibernate.cfg.Environment buildBytecodeProvider INFO: HHH000021: Bytecode provider name : javassist org.hibernate.internal.util.config.ConfigurationException: Could not locate cfg.xml resource [/HibernateTest/src/hibernate.cfg.xml] at org.hibernate.boot.cfgxml.internal.ConfigLoader.loadConfigXmlResource(ConfigLoader.java:53) at org.hibernate.boot.registry.StandardServiceRegistryBuilder.configure(StandardServiceRegistryBuilder.java:163) at org.hibernate.cfg.Configuration.configure(Configuration.java:259) at org.nitish.caller.HibernateTest.main(HibernateTest.java:17)
After making few changes (could not use session.close() in finally block I think that should not cause this error)
