How to integrate liferay bundled with tomcat with tomee (openEJB)

I have liferay 6.1 bundled with tomcat 7 (already populated with some 
data from users, that's why I cannot switch to liferay bundled with 
glassfish) and now I'm trying to develope new portlet with persistence 
and the whole EJB stuff.
I found that there should be some way to integrate tomcat 7 with openEJB 
and that's my question - how can I do that?
Now I have liferay portlet project with maven dependency

<dependency>
    <groupId>org.apache.openejb</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0-5</version>
</dependency>

and persistence.xml file

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0">
<persistence-unit name="kepler_v1PU">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
     <properties>
       <property name="openjpa.ConnectionURL" 
value="jdbc:mysql://localhost:3306/kepler_v1"/>
       <property name="openjpa.ConnectionDriverName" 
value="com.mysql.jdbc.Driver"/>
       <property name="openjpa.ConnectionUserName" value="xyz"/>
       <property name="openjpa.ConnectionPassword" value="xyz"/>
       <property name="openjpa.Log" value="DefaultLevel=WARN, Tool=INFO"/>
     </properties>
   </persistence-unit>
</persistence>

And I'm still getting the error
javax.persistence.PersistenceException: No Persistence provider for 
EntityManager named kepler_v1PU

Do you have any idea how can I resolve this issue?
Maybe it's related with duplicated jars (for example there are 
liferay-portal-6.1.1-ce-ga2/tomcat-7.0.27/lib/ext/persistence.jar and 
liferay-portal-6.1.1-ce-ga2/tomcat-7.0.27/lib/annotations-api.jar with 
implementations of the class javax.persistence.Persistence).

Hi

You use a jta datasource with resource local config, is it intended?

Does liferay provides hibernate? If yes set <provider> in your persistence
unit

Hi Romain,

Thanks for your answer and sorry that I left this thread for a long time.
I already solved my problem by adding openejb-core to the project

<dependency>
	<groupId>org.apache.openejb</groupId>
	<artifactId>openejb-core</artifactId>
	<version>4.5.0</version>
</dependency>

I'm not subscribed on tomee mailing list, but I hope you will find this 
asnwer.
Regards,
Piotrek.
