I'll try to explain my case in details. I have session bean with some operation: | @Stateless | @Remote(ContractFasade.class) | public class ContractFasadeBean implements ContractFasade { | @TransactionAttribute(TransactionAttributeType.REQUIRED) | public void createContract(some parameteres .... ) throws MyException{ | try{ | // creating contract into my provisioning system (by WS Client, | //Creating some file into file system and so on.) | .......................................................................... | // then creating contract into my databse(in my case - Oracle) | oracleManager.persist(someEntity); | oracleManager.merge(someOtherEntity); | ........................................................................... | | // make some other business logic | | | // also i tried to flush database, thought it can help to catch database exceptions. | | oracleManager.flush(); | } | catch(Exception e){ // catch any exceptions !!!!!!! | // i need this case !!!!!!!!!!! | // delete contract from my provisioning system. | } | } | } | for some times may occurred hibernate exceptions for example : ConstraintViolationException LockAcquisitionException and so on ... It's impossible to handle this :(. Exception occurred when CMT trying to commit database. Is it possible to handle this ? or maybe I'm on wrong way and there is any other pattern for it .. I can't find anything in the internet about it. Thank you very much again. _____________________ Regards, Paata Lominadze. Magticom LTD.
