Erro ao fazer o buildSessionFactory do hibernate

Front-end
#1

Por favor, alguém saberia me dizer pq isto está dando erro:

URL url = Thread.currentThread().getContextClassLoader().getResource(ARQUIVO_DE_CONFIGURACAO);

sessionFactory = new Configuration().configure(url).buildSessionFactory();

O arquivo de configuração xml é este:

<?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">

<!-- Arquivo gerado automaticamente - não edite!! -->

<hibernate-configuration>

	<!-- a SessionFactory instance listed as /jndi/name -->
	<session-factory>

		<!-- properties -->
		<property name="connection.datasource">jdbc/DSFH</property>
		<property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>
		<property name="show_sql">true</property>
		<property name="use_outer_join">false</property>
		<property name="transaction.manager_lookup_class">org.hibernate.transaction.WebSphereExtendedJTATransactionLookup</property>
		<property name="transaction.factory_class">org.hibernate.transaction.CMTTransactionFactory</property>
			<property name="connection.pool_size">1</property>
			<property name="hibernate.default_schema">FH</property>

		<!-- mapping files -->
		<mapping resource="br/com/santander/fh/to/UsuarioTO.hbm.xml"/>
		<mapping resource="br/com/santander/fh/to/log/LogTO.hbm.manual.xml"/>
	</session-factory>

</hibernate-configuration>

O XMl está sendo encontrado e mapeado no configure.
Quando vou executar apenas o buildSessionFactory() dá o seguinte erro:

Já refiz as configurações do jdbc várias vezes e as mesmas estão funcionando quando faço o teste.

O hibernate que utilizo é o 3.0.

Valew à todos!!!
