Hmmm...interesting...I can see it in my original message. Here is it again:
Code:
EntityManagerFactory emf = Persistence.createEntityManagerFactory("jbpm.mongodb.persistence.test", new HashMap<String, String>());

persistence.xml:
<persistence xmlns=" http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence"  
    xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance http://www.w3.org/2001/XMLSchema-instance"  
    xsi:schemaLocation=" http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence  http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0">  

    <!-- Tutorial "unit" -->  
    <persistence-unit name="jbpm.mongodb.persistence.test">  
        <properties>  
            <property name="datanucleus.ConnectionURL" value="mongodb:localhost/mng1"/>  
            <property name="datanucleus.storeManagerType" value="mongodb" />  
            <property name="datanucleus.autoCreateSchema" value="true" />  
        </properties>  
    </persistence-unit>  

</persistence>

error:
org.datanucleus.exceptions.NucleusUserException: Found Meta-Data for class org.drools.grid.service.directory.impl.AddressImpl but this class is not enhanced!! Please enhance the class before running DataNucleus.
