java.lang.ExceptionInInitializerError in the creation of hibernate configuration

Question

I'm working on a Hibernate project and I configured everything.

So, I generated the beans and hbm files.

Then, I wrote a test class to test the project(I used the Client class)

When I executed the code, the following exception was thrown:

java.lang.ExceptionInInitializerError
Caused by: java.lang.NullPointerException
at org.slf4j.LoggerFactory.singleImplementationSanityCheck(LoggerFactory.java:192)
at org.slf4j.LoggerFactory.performInitialization(LoggerFactory.java:113)
at org.slf4j.LoggerFactory.getILoggerFactory(LoggerFactory.java:269)
at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:242)
at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:255)
at org.aness.test.HiberM.<clinit>(HiberM.java:12)
Exception in thread "main"

the code is :

import org.aness.beans.*;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class HiberM {
 final static Logger logger = LoggerFactory.getLogger(Client.class);
public static void main(String[]arg){

    Configuration cfg = new Configuration().configure();
    SessionFactory sf =cfg.buildSessionFactory();
    Session s = sf.openSession();
    Transaction tx =s.beginTransaction();

    Client c =new Client();
    c.setRaisonSociale("peugeot algerie");
    c.setNumeroRc("3215468897");
    c.setIdentificationFiscale("888777999");
    c.setAdresseActivite("blida zone atlas");
    c.setTelephone("00213(0)25436996");
    c.setFax("00213(0)25436996");

    s.save(c);
    tx.commit();

   }

 }

that's the whole problem.

the hibernate cfg file is : *

<?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-configuration>
<session-factory name="apurement">

 <property name="hibernate.connection.username">root</property>
 <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
</session-factory>
</hibernate-configuration>

the client mapping is :

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

    </set>
    </class>
</hibernate-mapping>

Please post your hibernate.cfg.xml and your Client.hbm.xml file. Also, which Hibernate version are you using? — Vrushank

Do you have a hibernate.cfg.xml file? Did you try a different version of slf4j? — the_marcelo_r

Two possibilities :

Your Hibernate.cfg.xml is not on classpath. What folder is it in?

Else you may try updating the version of slf4j jar

I think you've hit this issue.

It seems you're using SLF4J version 1.5.8 (or thereabouts), as the source code of org.slf4j.LoggerFactory with tag 'SLF4J_1.5.8' has line numbers that match those in your stacktrace.

I would recommend updating to later version of SLF4J.
