Using Datanucleus JPA for MongoDB with JBPM5.2.0 gives an "class not enhanced" error
Hi,
I am trying to set JPA persistence for MongoDB with Datanucleus and I am getting the following error for org.drools.grid.service.directory.impl.AddressImpl. [details of the code and persistence.xml first].
Any ideas?
versions:
<dependency>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-core</artifactId>
<version>[2.9, )</version>
</dependency>
<dependency>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-mongodb</artifactId>

</dependency>
<dependency>
<groupId>org.datanucleus</groupId>
<artifactId>datanucleus-api-jpa</artifactId>
<version>[2.9, )</version>
</dependency>
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:
