Hibernate программа дает ошибку

Question

У меня есть создать проект Hibernate приложений, но я получаю следующее сообщение об ошибке, когда я запустить программу

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment). 
log4j:WARN Please initialize the log4j system properly. 
Exception in thread "main" org.hibernate.HibernateException: Could not parse configuration: /hibernate.cfg.xml

<?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">

You необходимо добавить файл конфигурации log4j в ваш путь к классам. Это может быть примерно так:

<?xml version="1.0" encoding="UTF-8"?> 
<Configuration status="WARN"> 
    <Appenders> 
    <Console name="Console" target="SYSTEM_OUT"> 
     <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/> 
    </Console> 
    </Appenders> 
    <Loggers> 
    <Root level="error"> 
     <AppenderRef ref="Console"/> 
    </Root> 
    </Loggers> 
</Configuration>
