I’m having trouble starting a transaction with Hibernate and MySQL while running in JUnit.

  • 0

I’m having trouble starting a transaction with Hibernate and MySQL while running in JUnit. I’m getting a HibernateException which states: “No TransactionManagerLookup specified”. I believe this error is because I don’t have a proper configuration setting for hibernate.transaction.manager_lookup_class.

I see that under the namespace of org.hibernate.transaction there are quite a few different lookup classes that I could use. All of the documentation that I could find on these was very vague. My question is what is the appropriate one for MySQL?

    To fix this I needed to make the following changes.

    1. Changed the hibernate.cfg.xml => hibernate.current_session_context_class from jta to thread.

    2. Changed the transaction manager to
      org.springframework.orm.hibernate3.HibernateTransactionManager
      in the bean configuration.

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