    I'm having a hard time with this error "org.hibernate.LazyInitializationException: failed to lazily initialize"

    Flemming Harms Novice

      I'm having a hard time with this error "org.hibernate.LazyInitializationException: failed to lazily initialize". I know the reason for this error but in my case it should not happen because all database transactions are happen in the same scope. (Well thats what I at least thought it did). But I can see the session is flushed because the transaction is committed inside the scope.

      I have a problem understanding why transactions are committed between calls of two local pojo's when I use "TransactionAttributeType.REQUIRED". I have pojo A which have a Session injected and when it starts, a number of changes happen and objects are created which is attached to the Hibernate session. In the same scope Pojo B is called which is looked up through JNDI, the session from A is passed into method on pojo B as parameter.  Pojo B also make changes and create a number of objects which is attach to the Hibernate session. When Pojo B return from it method the transaction is commited and the session is flushed. All the objects which was created is now detached and when Pojo C is referring to any of the object it throw an "LazyInitializationException". In my mind should first be committed when the Pojo A start method is done and the session is flushed and closed

      Please advise what I'm doing wrong and I how can I make sure it run in the same transaction so the session is not flushed.
