[jboss-user] [JBossCache] - Re: Problem with JBoss JDBCCacheLoader

Thank you so very much for looking into the problem. I was on leave as i had fallen ill and i just saw your reply. Our isolation level is REPEATABLE_READ and we are using REPL_SYNC cache mode

Please find below the complete configuration-
