blueprint entityManagerFactory usage issue

This is my persistence.xml

    org.hibernate.ejb.HibernatePersistence
    osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=jdbc/connectDB2)
    osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=jdbc/connectDB2)
    com.ibm.as400.access.AS400JDBCDriver
    true
    
        
        
        
    
    

this my blueprint part

the entitManagerFactory I have tried ref and value nothing . issue is that it cannot find camelJpaContainer ref/id and all is done pom xml and persisitence reference etc.

So either the blueprint entry or persistence issue? its something simple or something additional??

Appreciate some guidance in this as cannot find any solution. had this working in fuse 6.3 but not able in the jfuse 7.6.
