What transaction manager to use? (JPA, Spring)

Question

Hi! I'm developing a web application based on JPA + Hibernate, Spring and Wicket. I was wondering what's the best way of implementing transactions in my code? What transaction manager should I use? Should it be org.springframework.orm.jpa.JpaTransactionManager, or org.springframework.jdbc.datasource.DataSourceTransactionManager or something else? I'd like to use Spring for managing my transactions.

Answer 1

org.springframework.orm.jpa.JpaTransactionManager

My preference is to use this with annotation:

<tx:annotation-driven transaction-manager="myTxManager" />

Answer 2

nanda is right, you can only use JpaTransactionManager. The Transaction Manager abstraction we are talking about here is Spring's PlatformTransactionManager interface, and JPATransactionManager is the only implementation of that interface that understands JPA.

You should read the chapter Transaction Management from the Spring reference to better understand this topic.
