An improved method, apparatus, and computer instructions for creating and running batch jobs in an object oriented environment, such as a J2EE environment. A request to execute a batch job is received. A deployment descriptor file is processed to identify a batch bean to be invoked. This batch job session bean processes the request, parses deployment descriptor file that comprises definitions of relationships between other helper classes, entity and session beans. The identified batch bean is invoked to execute the batch job step in the order described in the deployment descriptor applying checkpoints at intervals specified in the descriptor.
