hi all
We are trying to use the JBoss cache with REPL_SYNC and we are using the sun
one as a appserver ,, while starting the cache service we are getting the
following error
Feb 15 18:35:07 DEBUG [main] cache.JBossCacheManagerImpl - before createService
Feb 15 18:35:07 DEBUG [main] cache.JBossCacheManagerImpl - after createService
Feb 15 18:35:07 DEBUG [main] cache.TreeCache - failed looking up TransactionMana
ger, will not use transactions
