Hi, I'm trying to do some benchmarking of jpa providers.
Here is my persistence.xml
Code:
<?xml version="1.0" encoding="UTF-8"?>
<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_2_0.xsd" version="2.0">

    <persistence-unit name="mongo_hibernate" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.ogm.jpa.HibernateOgmPersistence</provider>
        <class>model.Person</class>
        <properties>
            <property name="hibernate.ogm.datastore.provider" value="mongodb"/>
            <property name="hibernate.ogm.datastore.database" value="test"/>
        </properties>
    </persistence-unit>

    <persistence-unit name="mongo_eclipselink" transaction-type="RESOURCE_LOCAL">
        <class>model.Person</class>
        <properties>
            <property name="eclipselink.target-database" value="org.eclipse.persistence.nosql.adapters.mongo.MongoPlatform"/>
            <property name="eclipselink.nosql.connection-spec" value="org.eclipse.persistence.nosql.adapters.mongo.MongoConnectionSpec"/>
            <property name="eclipselink.nosql.property.mongo.port" value="27017"/>
            <property name="eclipselink.nosql.property.mongo.host" value="localhost"/>
            <property name="eclipselink.nosql.property.mongo.db" value="test"/>
            <property name="eclipselink.logging.level" value="WARNING"/>
        </properties>
    </persistence-unit>

</persistence>


and here is my exception
