• Get Criteria by associationPath

  - by niklassaers

  Hi guys, Every so often, I get a "org.hibernate.QueryException: duplicate association path: myAssociation". This is because the complex criteria I'm working with can define the same path in many places. I'd love to do something like Criteria association = myCriteria.getAssociation("wax"); if(association == null) association = myCriteria.createCriteria("wax"); Is there any such way that I can check if an association is already in place? Cheers Nik

• How to specify pessimistic lock with Criteria API?

  - by Reddy

  I am retrieving a list of objects in hibernate using Criteria API. However I need lock on those objects as another thread executing at the same time will get the exact objects and only one of the thread will succeed in absence of a pessimistic lock. I tried like below, but it is not working. List esns=session.createCriteria(Reddy_Pool.class) .add(Restrictions.eq("status", "AVAILABLE")) .add(Restrictions.eq("name", "REDDY2")) .addOrder(Order.asc("id")) .setMaxResults(n) .setLockMode(LockMode.PESSIMISTIC_WRITE) //not working at all .list();

• Rolling back a transaction in a Grails Service

  - by UltraVi01

  I have been updating all my services to be transactional by using Grail's ability to rollback when a RuntimeException is thrown in the service. I have, in most cases, doing this: def domain = new Domain(field: field) if (!domain.save()) { throw new RuntimeException() } Anyways, I wanted to verify that this indeed will rollback the transaction... it got me thinking as to whether at this point it's already been committed.. Also, if not, would setting flush:true change that? I am not very familiar with how Spring/Hibernate does all of this :)
