[hibernate-dev] No TransactionManagerLookup configured (in JTA environment, use of read-write or transactional second-level cache is not recommended)

Hi hibernate developers, Since various hibernate releases (3.2, 3.3 , 3.5beta2) I'm still wondering about following warning when using hibernate with JDBCTransactionFactory (= without JTA integration): TransactionManagerLookupFactory:80 - No TransactionManagerLookup configured (in JTA environment, use of read-write or transactional second-level cache is not recommended) 1. According documentation configuration of a TransactionManagerLookup is (only) required when using JTA environment, so why this warning? 2. Why is there a hint on how to use JTA environment, just using hibernate without JTA? 3. "transactional" concurrency strategy is supported by JBossCache and Infinispan and both require integration with JTA, so why should transactional second-level cache not be recommended ?! best regards Guenther D.
