Exception in hibernate

I am trying to develop a dynamic web project in Eclipse. I am using hibernate 3, tomcat 6 . My web page has a simple registration form. It accepts the user data and adds it to the db. I am using hibernate to do that part. I am getting this error. Have tried the solutions given in some of the similar questions asked but could not solve the issue. The error that I get is

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

My Customer.hbm.xml file is 

<?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">
         <generator class="assigned"/>
      </id>      
      <property name="PASSWORD" column="PASSWORD" type="String"/>
      <property name="CUSTOMERNAME" column="CUSTOMERNAME" type="String"/>
      <property name="CONTACTNUMBER" column="CONTACTNUMBER" type="String"/>     
   </class>
</hibernate-mapping>

And by hibernate config file is

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC

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

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

The changes that I made to my code to make it work are

In my Customer.hbm.xml file I changed the type of column from type="String" to type="string"

In the hibernate.cfg.xml file I had create the table in database already so I commented <property name="hbm2ddl.auto">create</property>

The problem seems to be system specific because the code was working without any hiccups in my home computer but was showing org.hibernate.HibernateException: Could not parse configuration: hibernate.cfg.xml error in my office computer.

At home I am using Eclipse Kepler, Tomcat 7 and hibernate 3.6.4 Final

In office there is Eclipse Galileo , Tomcat 6 and hibernate 3.x.x

I am not really sure want really solved the problem or the problem crept-in in the first place.

I noticed that your hibernate.cfg.xml refers to Customer.hbm.xml, and that file refers to a class com.pkg.bean.CustomerBean. It might not be wrong, but it doesn't follow the conventions, so I suspect there might be a problem there:

According to these conventions, hbm.xml files would be stored in the same package as their class. If that's the case, probably you should be referencing it as com/pkg/bean/Customer.hbm.xml.

Another convention is to name your files with the same name as your hbm.xml files. So then it would be CustomerBean.hbm.xml.

This is just a guess, based on the information you posted. I am not sure if any of these "conventions" are rules that would cause exceptions if broken (it's been a long time since I read the docs, and I usually follow best practices so I never tested to see what would happen if I didn't).

You have empty 

<property name="hbm2ddl.auto"></property>

Put some value there update/create.
