Components of a batch application

The batch application developer and the batch run time environment provide the components of a batch application.

The following tables describe the components of a batch application.

Component	Type	Implementation	Provider
Batch job step	POJO	com.ibm.websphere.BatchJobStepInterface	Batch application
Checkpoint algorithm	POJO	com.ibm.wsspi.batchCheckpointAlgorithm	Batch application (can use runtime-provided implementation instead)
Results algorithm	POJO	com.ibm.wsspi.batchResultsAlgorithm	Batch application (can use runtime-provided implementation instead)

Component	Type	Implementation	Provider
Batch job controller	Session bean		Batch run time environment
Checkpoint algorithm	POJO		Batch run time environment (applications can provide their own)
Results algorithm	POJO		Batch run time environment (applications can provide their own)
