We are working on Migration of Toplink to Eclipselink in our project.

We are extending base Junit class with AbstractTransactionalDataSourceSpringContextTests class from spring 2.0 in our existing Project which has many convenient methods to handle transactions(end transaction,start transaction).

So Same class I am trying to use to test the transactions after migrating to eclipselink but the transactions are not getting committed. The reason I can see from debug is TransactionStatus does not hold the object that needs to be persisted. I have highlighted the UnitOfWork which gets changed while executing the query and committing the transaction in Eclipsselink_UOW.PNG .

I have also tried with @Transactional annotation and AbstractTransactionalJUnit4SpringContextTests from spring 5 but I can see transactions are not getting committed.

FYI:

In persistence.xml

<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" xmlns="http://java.sun.com/xml/ns/persistence">

<property name="eclipselink.weaving" value="static" />
<property name="eclipselink.weaving.eager" value="true" />

</properties>
</persistence-unit>
</persistence>

And for transaction manager in springxml:

</bean>

</beans>

Am I missing any property to set ? Or is there any other way to be tested for eclipselink Could you please help me out on this as I am struct here to progress further?

Hi Radek,

In my Test cacses if i use entitymanager.getTransaction.commit(),
I can see the data gets persisted but i want to use the methods from AbstractTransactionalDataSourceSpringContextTests
to commit the transactions.
