Given that Microsoft has deprecated Transactional NTFS (TxF) : Microsoft strongly recommends developers utilize alternative means to achieve your application’s needs. Many scenarios that TxF was developed for can be achieved through simpler and more readily available techniques. Furthermore, TxF may not be available in future versions of Microsoft Windows. While TxF is a powerful set of APIs, there has been extremely limited developer interest in this API platform since Windows Vista primarily due to its complexity and various nuances which developers need to consider as part of application

Using Spring + Hibernate and transactional annotations. I'm trying to test the following: call a method that changes a User object then calls a @Transactional service method to persist it read the object back from the DB and insure it's values are correct after the method The first problem I had was reading the User object in step 2 just returned the one in the Hibernate level 1 cache and did not actually read from the database. I therefore manually evicted the object from the cache using the Session to force a read from the database. However, when I do this, the object values are never

This is my 1st time trying Spring3's @Scheduled , but found I cannot commit to DB. This is my code : @Service public class ServiceImpl implements Service , Serializable { @Inject private Dao dao; @Override @Scheduled(cron="0 0 * * * ?") @Transactional(rollbackFor=Exception.class) public void hourly() { // get xxx from dao , modify it dao.update(xxx); } } I think it should work , I can see it starts-up hourly and load xxx from DB , but data is not committed to DB. There's been tx:annotation-driven in spring's xml : <bean id="entityManagerFactoryApp" class="org.springframework.orm.jpa

I have a method annotated with @Transactional. I retrieve an object from my DB, change a field, and then return from the method. Without saving my object, the database gets updated anyway which is strange. Could you please tell me how to avoid this beahvior? This behaviour is one of the main purposes of transactionality. Before the transactional method is about to return, the transaction commits, meaning all changes to the managed entities are flushed to the database. If an error occurs, the transaction will be rolled back, meaning that no changes will be committed to the database. You are

The Spring docs do a fantastic job of describing transactional propagation properties. However, I was wondering if there are any well-known, real-world examples available which describe each of these properties more thoroughly in layman's terms? Brad PROPAGATION_REQUIRED class Service { @Transactional(propagation=Propagation.REQUIRED) public void doSomething() { // access a database using a DAO } } When doSomething() is called it will start a new transaction if the caller has not already started a transaction . If the caller of this method has already started a transaction then the callers'
