On top of page 52, the books lists the end of the hibernate configuration file. There, it lists the property "transaction.manager_lookup_class".

As far as I understood from the pages before, if hibernate.connection.factory_class property is not specified, the default will be assume of JDBCTransactionFactory.

If I understand correctly, the difference between JDBCTransactionFactory and JTATransactionFactory is that JTAxxx can be used in a full blown application server in the CMT context, while JDBCxxx can't be.

If my understanding is correct, then wouldn't having JDBCxxx infer that no "transaction.manager_lookup_class" property is even needed? Isn't that property only there to tell Hibernate which app specific class to use to plug into the JTA of that app server?

Thank you,

Correct

Ok, so they basically should have taken that line out and forgot... Whatever. Just wanted to make sure I wasn't misunderstanding anything.

Thanks for the reply.

No, the config files shown are OK. If you switch to JTA connection provider you also specify a JTA TM lookup.

Well, I wasn't saying that the config file is not OK. All I was saying that in its current form it is confusing. Since the connection.factory_class is omitted, JDBC is assumed. If so, no reason AT ALL to specify JTA TM lookup. It just clouds the matter.

IMHO, for clarity sake, I would either specify the connection.factory_class or omit JTA TM lookup.

It's just confusing what you are trying to show this way.

Thanks,
