Question

i’m trying to run some test cases, but when I try to store one object in the ddbb, there is no insert at all.

First, the test is declared with a @Transactional. So all the queries and operations to the ddbb will be in the same transaction. The part of the code where I get errors is:

public Concept storeConcept(Concept concept) throws DataAccessLayerException {

        if(concept!=null && concept.getUri()!=null){
            super.saveOrUpdate(concept);
            concept = this.findByID(concept.getUri());
            return concept;
        }

        return null;
    }

At this point, I can not see any kind of insert in the log of my ddbb (using hsql).

super: the class where this method is extends AbstractHibernateDAOSupport

The problem comes when I try to find the object stored:

ServiceExecutionException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1; nested exception is org.hibernate.StaleStateException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1

Because it is not stored. But when I debug this method, even I’m getting the same error, but the process can continue and the method is able to return the object stored.
Maybe that concept is somewhere in another session or in hibernate memory, but I can not really understand this problem.

Thanks in advance

EDIT transaction config

<bean id="transactionManager"
       class="org.springframework.orm.hibernate3.HibernateTransactionManager">
       <property name="sessionFactory" ref="sessionFactory" />
   </bean>

   <aop:aspectj-autoproxy proxy-target-class="true"/><!-- Se puede poner tb a nivel de bean -->

EDIT
I have aswell this error:

9898 [main] ERROR org.hibernate.event.def.AbstractFlushingEventListener - Could not synchronize database state with session

It’s very common error, and I have been reading something in other threads, but still can not find solution

After a while, I came back to this problem. I have realized, that the problem was not related with the store method itself. In my test method I had something like:

@Test
public void testCreateAnnotation() throws Exception {

  //Store the mediaObject related with the annotations to be created
    mediObjectService.storeMediaObject(MockGenericMediaObjectDataPool.GENERIC_MEDIA_OBJECT1);
    Assert.assertNotNull(geMO.getId());

    //Store annotation
    geAnno.setRelatedMediaObjectId(geMO.getId());
    geAnno.setMediaObjectInternalURI(geMO.getInternalURI());
    annotationService.createAnnotation(MockGenericAnnotationDataPool.TEST_ANNOTATION1);

}

These were two different calls to two different DAO, two different store services to two different tables. As you can see, in the same method. Here is the problem, these two calls must be in two different @Test methods.

    @Test
    public void testCreateAnnotation() throws Exception {

      //Store the mediaObject related with the annotations to be created
        mediObjectService.storeMediaObject(MockGenericMediaObjectDataPool.GENERIC_MEDIA_OBJECT1);

//        annotationService.createAnnotation(MockGenericAnnotationDataPool.TEST_ANNOTATION1);

    }

@Test
    public void testUpdateAnnotation() throws Exception {
        Assert.assertNotNull(annotationService);

        //Store the mediaObject related with the annotations to be created
//      mediObjectService.storeMediaObject(MockGenericMediaObjectDataPool.GENERIC_MEDIA_OBJECT1);


        GenericAnnotation geOriginalAnnotation = annotationService.createAnnotation(MockGenericAnnotationDataPool.TEST_ANNOTATION1);
    annotationService.updateAnnotation(geOriginalAnnotation);

    }

If somebody could explain me the reason of this behavior, I would be really grateful!!
Thanks for all your responses
