first question:what's these words' meaning?
[10-29 11:00:16.375 INFO TransactionManagerLookupFactory.getTransactionManagerLookup():33] No TransactionManagerLookup configured (in JTA environment, use of read-write or transactional second-level cache is not recommended)


second question:why there's no sql like "commit" printed on stdout when I used jdbc transaction?
I am using
MySQL, version: 4.1.14-nt,
InnoDB tables,
mysql-connector-java-3.1.11 org.gjt.mm.mysql.Driver
Using dialect: org.hibernate.dialect.MySQLInnoDBDialect
org.hibernate.connection.ProxoolConnectionProvider


and it does print these informations:
[10-29 11:00:15.562 INFO ProxoolConnectionProvider.configure():166] autocommit mode: false
[10-29 11:00:16.406 INFO SettingsFactory.buildSettings():257] Echoing all SQL to stdout


everything works quit well but I am confused why the sql printed doesnot include such words like "begin", "end","commit" which should be a must for jdbc transaction.

thanks.
