I am trying to connect to a MongoDB using this persistence.xml file. My mongodb instance is not using any username or password.
<?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="tryAll" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ogm.jpa.HibernateOgmPersistence</provider>
<class>com.learning.beans.User</class>
<properties>
<!-- <property name="hibernate.ogm.datastore.provider" value="MONGODB"/> -->
<property name="hibernate.ogm.datastore.provider" value="org.hibernate.ogm.datastore.mongodb.impl.MongoDBDatastoreProvider"/>
<property name="hibernate.ogm.mongodb.database" value="test"/>
<property name="hibernate.ogm.mongodb.host" value="127.0.0.1"/>
<property name="hibernate.ogm.mongodb.port" value="27017"/>
</properties>
</persistence-unit>
</persistence>
I am creating an EntityManager instance using this :
EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("tryAll");
EntityManager manager = entityManagerFactory.createEntityManager();
I cannot see what is wrong in this code...??
Complete error stack is as follows :

What you are missing is three more properties in persistence.xml to configure DB connection:
- hibernate.ogm.mongodb.database
The database to connect to. This property has no default value.- hibernate.ogm.mongodb.username
The username used when connecting to the MongoDB server. This property has no default value.- hibernate.ogm.mongodb.password
The password used to connect to the MongoDB server. This property has no default value. This property is ignored if the username isn’t specified.
As you will find here you can also use more generic properties.
Properties common to all/most stores are named hibernate.ogm.datastore.* now, so e.g. there is hibernate.ogm.datastore.host, hibernate.ogm.datastore.username, hibernate.ogm.datastore.database etc. Properties specific to a single store are named hibernate.ogm..*, e.g. hibernate.ogm.mongodb.connection_timeout.
