Erro no Spring ao fazer lookup de um DataSource

Assuntos Gerais
#1

Estou usando JBoss 6.0, Spring, Hibernate + JPA

Criei o DataSource através desse mapeamento

<?xml version="1.0" encoding="UTF-8"?> <datasources> <local-tx-datasource> <jndi-name>LogDS</jndi-name> <connection-url>jdbc:oracle:thin:@//xprt_virtual:1521/xe</connection-url> <driver-class>oracle.jdbc.driver.OracleDriver</driver-class> <user-name>XXXt</user-name> <password>XXX</password> <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name> <metadata> <type-mapping>Oracle11g</type-mapping> </metadata> </local-tx-datasource> </datasources>

Fiz o mapeamento no persistence.xml

[code]
<persistence-unit name=“Log” transaction-type=“JTA”>
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:/LogDS</jta-data-source>

	&lt;class&gt;com.xxx.vo.IntegrationLog&lt;/class&gt;
  	 
  &lt;properties&gt;
	&lt;property name="jboss.entity.manager.jndi.name" value="java:/Log"/&gt;		
	&lt;property name="jboss.entity.manager.factory.jndi.name" value="java:/LogPUFactory" /&gt;
     &lt;property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/&gt;
     &lt;property name="hibernate.show_sql" value="false"/&gt;
     &lt;property name="transaction.factory_class" value="org.hibernate.transaction.JTATransactionFactory"/&gt;
   	 &lt;property name="transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/&gt;
  &lt;/properties&gt;

</persistence-unit>[/code]

E também o mapeamento do Spring

        &lt;jee:jndi-lookup id="entityManagerFactory" jndi-name="java:/CorePUFactory" expected-type="javax.persistence.EntityManagerFactory"/&gt;
        &lt;jee:jndi-lookup id="entityManagerFactoryLog" jndi-name="java:/LogPUFactory" expected-type="javax.persistence.EntityManagerFactory"/&gt;    

      &lt;context:annotation-config /&gt;
    
      &lt;bean id="transactionManager-01" class="org.hibernate.transaction.JBossTransactionManagerLookup"&gt;
            &lt;property name="transactionManager" ref="entityManagerFactory"/&gt;
      &lt;/bean&gt;
    
      &lt;bean id="transactionManager-02" class="org.hibernate.transaction.JBossTransactionManagerLookup"&gt;
            &lt;property name="transactionManager" ref="entityManagerFactoryLog"/&gt;
      &lt;/bean&gt;    
    
      &lt;tx:annotation-driven transaction-manager="transactionManager"/&gt;


    &lt;mvc:annotation-driven /&gt;

Já existia um DataSource que está funcionando perfeitamente, agora ao tentar incluir o segundo, estou com o seguinte erro:
