I've been currently working on a Maven + Spring + Hibernate project. Actually, this is just a test project just to get familiar on how Spring works with Hibernate (+Maven). I've already setup and prepare the necessary dependencies. i.e. the appcontext.xml for Spring, the persistence.xml for Hibernate, the entity and DAO objects for JPA/Persistence/Hibernate.
During debug, persist method throws Transactionrequiredexception, no transaction in progress. I don't know what's causing this

Please help me resolving this

The root of your issue is that the bean you've annotated with the @Transactional
annotation is not being picked up by the context that contains the tx:annotation-driven
post processor. You have a couple options. Move the @Transactional
to a bean that is loaded by the context that contains the tx:annotation-driven
post processor or move the tx:annotation-driven
post processor into the same context that the @Transactional
bean is being loaded.
The answer here is a similar situation.
