Hibernate JPA and Spring javax.persistence.TransactionRequiredException: no transaction is in progress

Question

Hi All, I call

entityManager.flush()

got follow excetion. I am using Hibernate JAP

Answer 1

Ensure that you have an active transaction when this statement executes. If you are using JPA use EntityManager.getTransaction().begin(). This is assuming that you are using JPA outside a JTA transaction scope.

If you are running the application inside a container with JTA support you can also use JTA UserTransaction to manage transactions.

Answer 2

In fact I am using spring annotation @Transactional

Answer 3

Can you post the related Spring configuration?

Answer 4

make sure your handler is 'public'

@Transactional 
@RequestMapping('/test')
public String doTest() {
  // do your stuff here 
  return 'testview';
}

Answer 5

Make sure that your spring configuration includes the following line:

<tx:annotation-driven mode="aspectj" transaction-manager="transactionManager" />

mode can be either proxy or aspectj and transaction-manager has to point to your transaction manager been.

Answer 6

I am not able to update my database. my configuration file contains

I am using @Transactional annotation.

Surprisingly when I update it using JUNIT. It works fine but it is not working while updating using my application

Answer 7

Same was happening to me using spring 3.0.0 / 3.0.3. Data was persisted in MySQL from JUnit but not from the tomcat server. After so much work I gave up on RESOURCE_LOCAL for JTA.

This worked for me http://erich.soomsam.net/2007/04/24/spring-jpa-and-jta-with-hibernate-and-jotm/ It uses JTA and depends on JOTM.

Answer 8

For JBoss 4.0 and Hibernate, I fixed this problem by adding some transaction manager properties to my EntityManagerFactoryBean definition:

  <bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="xaDs" />
<property name="jpaProperties">
  <props>
    <prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory
    </prop>
    <prop key="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup
    </prop>
  </props>
</property>

I found the soluton on this message board thread.

Answer 9

After encountering this problem myself and spending a few hours trying to get it resolved I finally found a reason for it: Spring has a bug and can't maintain transactions with @Transactional annotation if the same class has @Service annotation for the means of autowiring.

Once the @Service annotation was removed from the service class in question, and an appropriate bean was declared in the XML config:

<bean id="myService" class="com.example.myapp.service.MyServiceImpl" />

the problem is gone.
