Integration

I have a Spring Java web app deployed on OC4J 10.1.3.3 using Toplink as the container managed persistence. When my app is launched a named query is executed that uses JPQL to load up collections of objects. It is failing with the subject line exception.
org.springframework.transaction.UnexpectedRollbackException: JTA transaction unexpectedly rolled back (maybe due to a timeout); nested exception is javax.transaction.RollbackException: Timed out

If, however, I then modify the URL and force an action that will re-execute the same query, it works fine.

Any ideas on which configuration settings I should investigage/change to enable this to work the first time through?

I am not dealing with large collections here. At this point, there are 11 main objects that have children/parents. Re-execution of the query happens very fast.

Thank you!
