JpaItemWriter step scope entityManagerFactory error

[shriny]

When using JpaItemWriter with step scope , I am seeing this error

This works if it is not step scoped. Its something to do with late binding but I don't any work around for this issue

Caused by: java.lang.IllegalArgumentException: No EntityManagerFactory specified

Has anyone encountered this issue?

It works for me. Are you sure you are not using the writer outside a transaction? What transaction manager do you use with the JobRepository?

Can you please post the sample code showing usage of JPAItemWriter ? My code looks like as follows. I am trying to read data from a flat file and write to db2 database table. I did search on this forum as well as on internet but didn't find sample code. I don't understand how JpaItemWriter will know which table to udpate. I can attach my source if needed.

Thanks,
Jagdish
