Исключение в спящем режиме

Я пытаюсь разработать динамический веб-проект в Eclipse. Я использую hibernate 3, tomcat 6. Моя веб-страница имеет простую регистрационную форму. Он принимает пользовательские данные и добавляет их в db. Я использую hibernate для выполнения этой части. Я получаю эту ошибку. Попробовали решения, заданные в некоторых подобных вопросах, но не смогли решить проблему. Ошибка, которую я получаю

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.

Файл My Customer.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>

 <!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
   <class name="com.pkg.bean.CustomerBean" table="r_customer">      
      <id name="CUSTOMERID"  column="CUSTOMERID" type="String">

И с помощью конфигурационного файла hibernate

             <mapping resource="Customer.hbm.xml"/>

    </session-factory>
</hibernate-configuration>

Может кто-нибудь, пожалуйста, помогите мне решить проблему.
