[jboss-user] [EJB/JBoss] - How can we use oracle hints in EJB (3.0)?

[hudowski]

We create EJB queries and we want to use oracle hints (e.g. FIRST_ROWS, index(table_name index_name)) 
in these queries. As we know, hibernate doesn't support this funcionality. 
We tried to use Apache OpenJPA, but in the line createQuery we've got an exception:

org.apache.openjpa.persistence.InvalidStateException: 
This operation cannot be performed while a Transaction is active.

and we can't find the reason of this exception. 
What's the simplest way to use oracle's hints in EJB queries?
