I am using Kundera with mongodb on a windows 7 box. I am trying to use int data type. But I am getting the following error.
Exception in thread "main" com.impetus.kundera.configure.schema.SchemaGenerationException: Persistence unit for class : int is not loaded

My entity object has the following fields
#Id

private String messageId;
#Column(name = "SUBJECT")
private String subject;
#Column(name = "BODY")
private String body;
#Column(name = "zipcode")
private int zipcode;
#Embedded
private Contact from;
My persistence.xml looks like below
<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="2.0">

I wasted 2 days around this but not able to get the solution. Any help would be appreciated
Can you try removing
property name="" value="datastore_mongo.jar"
and share test.jar entities code ? Also , which version of Kundera are you using ?
I had a class for which I have declared the one to one mapping annotation for a int data type which was never used.
This should not cause any problem but the way kundera populates metadata via reflection is the issue.

I have a simple implemenation of JPA 2.0 annotations that is not working. This is running in karaf 4.0.5 as a server. Below are listed the relevant excerpts from persistence.xml, blueprint.xml and the class. The exception is listed at the bottom.
The issue is that the EntityManager em is always null. I expected this to be injected by blueprint.
Can anyone point out where I've gone wrong?
Class

import javax.transaction.Transactional;

Your datasource configuration appears to be missing. You are using osgi.jndi.service.name=MotorDB that is nowhere declared. So there is no service implementing javax.sql.DataSource
There has to be something similar to the following example which uses Oracle.
Change accordingly for other DBMS:
...
<bean id="dataSourceBeanMfgLookupService" class="oracle.jdbc.pool.OracleDataSource">
<property name="URL" value="???"/>
<property name="user" value="???"/>
<property name="password" value="???"/>
</bean>
<service id="dataSourceMfgLookupService" interface="javax.sql.DataSource" ref="dataSourceBeanMfgLookupService">
<service-properties>
<entry key="osgi.jndi.service.name" value="MotorDB" />
</service-properties>
</service>
...
Furthermore you may have to specify a persistence-provider in your persistence.xml. If you used hibernate with Oracle 10g it would look somehow like this:
<persistence xmlns="http://java.sun.com/xml/ns/persistence" ...>
<provider>org.hibernate.ejb.HibernatePersistence</provider>
...
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
<property name="hibernate.temp.use_jdbc_metadata_defaults" value="false" />
...
Then you can link your datasource to your service:
<bean id="mfgLookupEntityImpl" class="LookupMfgService">
<jpa:context property="em" unitname="pu_motordb3" />
<tx:transaction method="*" value="Required" />
</bean>
If this still does not inject the EM provide a setter:
public void setEm(EntityManager entityManager) {
this.em = entityManager;
}
AFAIK there was/is a bug that property injection only worked if a setter was available.
The cause was an issue with karaf 4.0.5 and openjpa 2.4.1. It has been resolved in karaf 4.0.6

UserTransaction instance = Transaction.instance();
List<Officer> list = em.createNamedQuery("findOfficerByEmpIDFetchAssigners").setParameter("id", employeeID).getResultList();
I placed the persistence.xml in the under ejb/resources/META-INF folder. I have tried the previous posts regarding the NamedQuery Not found issue. That is not fixing my issue
Please help me to figure out the issue. Thanks
I have resolved the issue. I have added the the following class tag in persistence.xml to resolve the issue,
<class>com.wachovia.apps.amaster.orm.Officer</class>
The order of the tags are important in persistence.xml. In my case, this class tag must be added before the <properties> tag and after the <jta-data-source> tag.

Im using CTM so Im calling the PU in a stateless session bean;
#Stateless
public class TicketDAOImpl implements TicketDAO {
#PersistenceContext(unitName = "NoSQL_PU")
private EntityManager em;
}
Ive been following the eclipselink guide but I can't find anything pertaining to this.
The problem was with my persistence unit. By default ALL the Entity classes are included, So both my NoSQL and SQL entities were being passed to both the SQL and the NoSQL persistence units. The solution was just to specify the entities inside the persistence.xml persistence unit.
<persistence-unit name="Dastrax_NoSQL_PU" transaction-type="JTA">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>declare_your_entity_1</class>
<class>declare_your_entity_2</class>

<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="dev"/>
<property name="eclipselink.logging.level" value="FINEST"/>
</properties>
</persistence-unit>
I got the ClassCastException with EclipseLink 2.6.0.
Turned out it was a bug and it is fixed in 2.6.1
https://www.eclipse.org/eclipselink/downloads/milestones.php
Bug: https://www.eclipse.org/forums/index.php/t/1068464/
Note: At this moment 2.6.1 is not officially released but it worked great for me so far.
I think the correct answer would contain true in the exclude-unlisted-classes field. In other words, it would exclude the entity classes not belonging to the NoSQL JPA. Therefore, the persistence.xml should look as follows:
<persistence-unit name="Dastrax_NoSQL_PU" transaction-type="JTA">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<class>declare_your_entity_1</class>
<class>declare_your_entity_2</class>
<exclude-unlisted-classes>true</exclude-unlisted-classes>

<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"/>

My bean looks like this:

#Table(name="tbl_User")
public class UserPDO implements Serializable {
private long id;
private String username;
private String password;
public UserPDO() {}
#Id
#GeneratedValue(strategy=GenerationType.SEQUENCE, generator="user_seq_gen")

public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
... }
My persistence.xml looks like this:

The table is created correctly, so is the sequence. But when I want to create a new user object via
public <T> T create(T t) {
this.em.persist(t);
this.em.flush();
this.em.refresh(t);
return t;
}
I get the exception mentioned above. I found some questions/answers here that suggest that deactiving runtime-enhancement should do the trick. But it didn't work for me. My first idea was, that it might be a Classloader-Leak. I copied postgres-driver and openjpa-jars into the glassfish/lib-folder.
Can anybody help? Thanks!
I am using openejb as my standalone container to run my unit testcases, in all the test in all the tests i was able to retrieve the values but not able to insert or update. Even if i try entitymanager.merge(obj), it is selecting the value correctly but it is not updating it.
I am new to this , so please help me with this error
thanks in advance

my dao method
tp.setname("van");
tp.settype("vehicle");
//entityManager.getTransaction().begin();
entityManager.merge(tp);
//entityManager.getTransaction().commit();
Do the followings for
Persist new entity:
Transport tp = new Transport();
tp.setname("van");
tp.settype("vehicle");
entityManager.getTransaction().begin();
entityManager.persist(tp);
entityManager.getTransaction().commit();
Update existing entity:
Query qry = entityManager.createQuery("Select t from
Transport t where t.type ='vechicle'");
List list = qry.getResultList();
//assume result return single entity
Transport tp = list.get(0);
tp.setInspectionDone(new Date()) ;
entityManager.getTransaction().begin();
entityManager.merge(tp);
entityManager.getTransaction().commit();
I think you need to ad #Transactional annotation in your class or method
