I'm trying to learn Spring Batch, but the startup guide is very confusing. Comments like
You can get a pretty good idea about how to set up a job by examining the unit tests in the org.springframework.batch.sample package (in src/main/java) and the configuration in src/main/resources/jobs.
aren't exactly helpful. Also I find the Sample project very complicated (17 non-empty Namespaces with 109 classes)! Is there a simpler place to get started with Spring Batch?

Use a class SpringBatchScheduler to configure the scheduling of Spring Batch Jobs. A method called launchJob() will be registered as a scheduled task. To trigger the scheduled Spring Batch job, add the conditional flag for firing the job only when the flag is set to true (using the below code).
if Step aStep fails for job someJob ( aStep has thrown some SQLException ). Then someJob is continued to execute. But after successful completion of cStep , BATCH_STATUS for someJob is COMPLETED but EXIT_STATUS = FAILED . Also BATCH_STATUS and EXIT_STATUS of other steps are as follows.
Because the script launching the job must kick off a Java Virtual Machine, there needs to be a class with a main method to act as the primary entry point. Spring Batch provides an implementation that serves just this purpose: CommandLineJobRunner .
A few pointers:
