I have a quick Hibernate question - Any takers?

I am using JPA and the EntityManager to persist my data. My jUnit test works fine but when I look in my database I don't see the data I just persisted. Does anybody know why this is happening?

Thanks!

Are you commiting the transaction in your tests? or using the spring transactionConfiguration with rollback set?

Hm... That is a good question. I am NOT committing the transaction in my test. However, I am using the JPATransactionManager to coordinate my transations. It is defined like this:

Code:

        <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
      <property name="dataSource">
         <ref bean="data-source" />
      </property>      
      <property name="persistenceUnitName">
         <value>local-jedi-persistence-test</value>
      </property>
      <property name="persistenceXmlLocation">
         <value>/itest/local-jedi-persistence.xml</value>
      </property>
   </bean>


   <bean id="tranactionManager" name="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
      <property name="entityManagerFactory" ref="entityManagerFactory" />
   </bean>

I am using @Transactional annotation in my Junit4 test too.

Do I have an error in my configuration? Did I leave out something?

Do I need to wire up a HibernateJPADialect inside my transactionManager even though dialect is defined in my persistence.xml file? What is the purpose of the HibernateJPADialect?

I resolved this by and Spring Transactional annotation to my service method; which in turn used my DAOs to persist.

Thanks!
