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

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance

    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence 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.
