a different object with the same identifier value was already associated with the session

[Kumar Sushil]

Hello all,

I am doing following activity in my applicatin -
1. Fetch object using getHibernateTemplate().get(String entityName, Object obj).
2. If in step #1, object is present in database, then call getHibernateTemplate().delete(String entityName, Object id).
3. Fetch object using getHibernateTemplate().get(String entityName, Object obj), so it will give null.
4. Populate object with same property having by object in step #1.
5. Call getHibernateTemplate().saveOrUpdate(String entityName, Object obj). passed object was populated in step #4.

On executing step #5, I am getting exception- a different object with the same identifier value was already associated with the session

Please note that all steps from #1 to #5 are part of single transaction.
Could you please advice me to handle this exception.

Thanks in advance.

What order are your statements executing in? Are you printing them out? Often times deletes will be executed after inserts. You can try flushing the session after the delete to make sure it executes first. You can also call evict to make sure that object is not in the session, before creating a new. Use of hibernate template is now discouraged. See the Spring documentation for the preferred approach.
