Why jndi-lookup is not creating a EntityManagerFactory bean definition from JNDI? - jpa-2.0

Question

I created my app as J2EE app in JDeveloper 11g. It uses JSF 2.1, Spring-core 3.2.1 and Spring-data-jpa-1.4.4 among others Spring necesary modules. I've created a datasource in the integrated WebLogic server within the default domain. When I try to run the app the following error is showing up.
weblogic.application.ModuleException: :org.springframework.beans.factory.NoSuchBeanDefinitionException:No qualifying bean of type [javax.persistence.EntityManagerFactory] is defined: expected single bean but found 0:

My WEB-INF/web.xml has the configuration to setting up the JSF servlet and Spring listeners:
<?xml version = '1.0' encoding = 'windows-1252'?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
<listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>
<context-param>
<param-name>javax.faces.FACELETS_VIEW_MAPPINGS</param-name>
<param-value>*.jsf;*.xhtml</param-value>
</context-param>
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
</web-app>
Then there is the WEB-INF/faces-config.xml with the Spring integration:
<?xml version="1.0" encoding="windows-1252"?>
<faces-config xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
version="2.0">
<application>
<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
</application>
</faces-config>
Then there is WEB-INF/applicationContext.xml with the Spring config:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd

http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd
http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd

<context:annotation-config/>
<context:component-scan base-package="com.myapp.*"/>

<tx:annotation-driven transaction-manager="transactionManager"/>
<bean id="transactionManager" class="org.springframework.transaction.jta.WebLogicJtaTransactionManager"/>
</beans>
Then I created the persistence file under META-INF/persistence.xml
<?xml version="1.0" encoding="windows-1252" ?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

version="2.0">

<class>org.eclipse.persistence.example.jpa.server.business.CellAttribute</class>
<properties>
<property name="eclipselink.target-server" value="WebLogic 10"/>
</properties>
</persistence-unit>
</persistence>
My Entity and Repository classes looks like this:
... imports
#Entity
#Table(name = "CONTRIBUYENTE")
public class ContribuyenteEntity implements Serializable {
#SuppressWarnings("compatibility:-6161811794505268140")
private static final long serialVersionUID = 7000366567373058605L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "ID_CONTRB")
private Long idContrb;
... get and set methods
}
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
-------------------------------------------------------------------------------------
#Repository
public interface ContribuyenteRepository extends CrudRepository<ContribuyenteEntity, Long>{
}
I've performed the extra configuration on the server as the Oracle docs indicates:
http://docs.oracle.com/middleware/1212/toplink/TLADG/tlandwls.htm#BABEDCEI
I don't really found out why the <jee:jndi-lookup id="dataSource" jndi-name="MYJNDI"/> is not registering the EntityManagerFactory bean within the context. I'd really appreciate any help you can provide. Regards!
