Hi, We have an J2EE application in JBoss-3.2.3, which uses Hibernate as a MBean. The version of Hibernate that we are using is 2.1.3. Till sometime back we were using JBossCache1.2 with Hibernate.
Our application has several SLSB(with container managed transactions) which give a call to Persistence manager which internally uses the Hibernate service to do any database operations like save,update,delete etc... We have enabled second level cache in Hibernate. The application was running fine(except for some frequent cache locking issues because of PESSIMISTIC locking) Some days back we shifted from JBossCache1.2 to JBossCache1.2.4, to avoid some cache locking issues that we were facing because of PESSIMISTIC locking. We have specified OPTIMISTIC locking for JBossCache1.2.4 in our config files. Now all of a sudden we are seeing the following exception being thrown in the application: 16:10:18,330 WARN [OptimisticTxInterceptor] runPreparePhase() failed.

I saw an post on this forum by "DashV", which talks about the same. So, my questions regarding this are: 1) Is this case similar to the one mentioned by "DashV" at: http://www.jboss.org/index.html?module=bb&op=viewtopic&t=71394&postdays=0&postorder=asc&start=0 2) If yes, is my appplication required to catch these exceptions and do appropriate action(again, what would be an approproiate action in this case)? P.S.: Since my SLSB are having container managed transactions, i am never dealing with transactions in my code. So, if at all i have to handle these exceptions in our code, is this the appropriate thing to do? 3) Are there any known operations that are going to result in these exceptions(so that our code can handle only those cases). 4) If the answer to the question 3 is NO, then do we have to handle these exception in each method in the SLSB, that does a database operation through Hibernate? 5) And finally, if at all our code is to handle these exceptions, what would the appropriate action be? Re-invoke the same operation again? I hope that someone answers these questions. Thank you.
