ArrayList cannot be cast to org.springframework.batch.core.JobParameter

Question

I want to send a list from rest client to rest web service which will start a job in Spring Batch. Is that possible or must I save the list in database/flatfile before start

Answer 1

Batch jobs are meant to be Time based not Event based. So, you can't pass the information from Rest service to your Job instance. Before you trigger the job in your controller method either write the list in temporary flat file or store it in a database, from where your Job can read it.
