Some file operations , write some data to file. </atomic operations> I want both operations to be atomic. My Local SSL EJB is a CMT and its method 'transaction' attribute is marked for new transaction. void myAtomicProcess(String a, String b)throws MyException{ | | //1. update db... | | //2. update file ... | | } If there is any exception while comitting[at the end of method] , I want to rolback my changes done to file i,e restore the file as it was.
