Couple of things jump out at me:

1) If the method is taking more than 5 minutes to execute, very likely that the root of this problem is a UserTx timeout.  I wouldn't futz with the global setting, but override on this method alone

2) Any tuning you can do to optimize those batch inserts?  You mention "repeatedly asking [the EM] to persist a large number of objects".  Check the section on JDBC Batch Inserts, flushing the EM, etc from the Hibernate Documentation:


...though not directly related to your problem, you might be able to get some dramatic performance improvements, depending upon your current implementation.
