The Classic issue of entityManager.persist(): no errors but not inserting to db

Question

I am having a strange issue while inserting a new entry.

Problem: entityManager.persist(myEntiy) : line is executed but no entry is created in the db.

I know many had this issue before and i have read all of those posts but none of it answers my problem. I am not inserting an entry for the first time. So i have did the configuration and other basic things right. That means I do use <tx:annotation-driven transaction-manager="jpaTransactionManager"/> in my spring-core.xml and I do use an @Transactionalon top of the methods in my dao.

Solutions tried: Adding entityManager.flush() after persist, but this resulted in

javax.persistence.TransactionRequiredException: no transaction is in progress.

Also tried:

em.getTransaction().begin(); em.persist(entity); em.getTransaction().commit();

which resulted in

Not allowed to create transaction on shared EntityManager

Then saw someone saying the problem may be the

AbstractSaveEventListener - delaying identity-insert due to no transaction in progress

but i didnt have anything in log saying that this may be the cause. And i dont have a clue what exactly is the solution if that is the issue. My hibernate log ends with the lines.

DEBUG 0412185908 [80-exec-2 SqlStatementLogger.java: 104] select mySchema.sequence_for_my_entity_PK.nextval from dual

no errors whatsoever there. Any help is appreciated.

My spring-core.xml have:

<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />
<bean id="entityManagerFactory"  class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="jpaVendorAdapter" ref= "jpaVendorAdapter"/>
<property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml" />
<property name="persistenceUnitName" value="punit" />
<property name="jpaDialect" ref="jpaDialect" />
</bean>
<bean id="jpaDialect" class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />   	
<tx:annotation-driven transaction-manager="jpaTransactionManager"/>
<bean id="jpaTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
<property name="dataSource" ref="dataSource" />
<property name="jpaDialect" ref="jpaDialect" />
</bean> 
<bean id="jpaVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="databasePlatform" value="${local.datasource.database.platform}" /> 
<property name="generateDdl" value="true" />
<property name="showSql" value="true" />
</bean> 
<bean id="dataSource" class="${local.datasource.database.datasource}">
<property name="dataSourceName" value="${local.datasource.database.name}" />
<property name="URL" value="${local.datasource.database.url}" />
<property name="user" value="${local.datasource.database.user}" />
<property name="password" value="${local.datasource.database.password}" />
</bean>

And the DaoImpl is:

@Repository
public class MyDaoImpl implements MyDao {
	protected EntityManager entityManager;
	@Autowired
	AnotherDao anotherDao;
	public EntityManager getEntityManager() {
		return entityManager;
	}
	@PersistenceContext
	public void setEntityManager(EntityManager entityManager) {
		this.entityManager = entityManager;
	}
	@Override
	@Transactional
	public String saveNewInfo(Data dataObject, String scheduleType){
		String uniqueSessionId = null;
		History history = new History();
		SessionIdentifierGenerator sessionIdentifierGenerator = new SessionIdentifierGenerator();
		uniqueSessionId = sessionIdentifierGenerator.nextSessionId();
		Type type = anotherDao
					.getAppObject(dataObject.getApplication());
		history.setType(type.getType());
		history.setSessionId(uniqueSessionId);
		history.setSchedulerType(scheduleType);
		history.setStatusCode("1");
		history.setVersionNumber(dataObject.getVersionNumber());		
		entityManager.persist(history);
		return uniqueSessionId;
	}
}

So the problem is solved. I added these two lines to my Spring-Core.xml

<bean id="myDao"  class="com.myPackage.dao.myDaoImpl"/>
<bean id="myAnotherDao" class="com.myPackage.dao.myAnotherDaoImpl" />

I never used to specify by dao beans like this before in the spring-core and still it used to work for update ,delete and even for persisting a new entry(Everybody is welcome to clarify this part).But this is the solution that fixed my issue.
