throws java.lang.IllegalStateException
Mark the current transaction for rollback. The transaction will become permanently marked for rollback. A transaction marked for rollback can never commit. Only enterprise beans with container- managed transactions are allowed to use this method.

IllegalStateException – The Container throws the exception if the instance is not allowed to use this method (i.e. the instance is of a bean with beanmanaged transactions).
