Olá pessoal, estou com um problema com o hibernate e já não sei mais o que fazer.
Estou usando o Mysql e o hibernate-3.5.0.
O problema é o seguinte: tenho os arquivos People.java e People.hbm.xml, o banco com uma tablea chamada people.
Toda vez que rodo aplicação, o seguinte erro aparece:

ERRO!!!--> org.hibernate.MappingException: Error reading resource: People.hbm.xml
Exception in thread "main" java.lang.NullPointerException
É como se ele não encontrasse meu People.hbm ou como se ele estivesse incorreto sendo que meus arquivos estão todos na mesma pasta src .
De início eu apenas tinha o arquivo de configuração do hibernate "hibernate.cfg.xml" fazendo o mapeando , porém foi necessário inserir outros dois arquivos, o log4j.properties e o hibernate.properties pois o compilador exigiu.
Aqui meu People.hbm.xml
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="People">
<property name="nome"/>
<property name="idade"/>
</class>
</hibernate-mapping>
Hibernate.cfg.xml
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/mysql</property>
<property name="hibernate.connection.username">root</property>
<mapping resource="People.hbm.xml"/>
</session-factory>
</hibernate-configuration>
Alguém aí poderia me ajudar com esse problema?
