HibernateItemWriter and hibernate4

[engywook]

Hi,
I'm using spring-batch 2.1.8.RELEASE. We're upgrading to spring 3.1 and hibernate 4.1.6 and ran into an issue with HibernateItemWriter. I believe it's because HibernateItemWriter is using the hibernate3.HibernateTemplate class, which is incompatible with hibernate 4. Is this a known issue in HibernateItemWriter? Here's the stacktrace.
Thanks

You might want to take this question to the Spring DATA forum?
You could also diff hibernate4.SessionHolder source against hibernate3.SessionHolder source to see what the difference is?

Looking at the code (https://github.com/SpringSource/spri...temWriter.java) HibernateItemWriter only works up to Hibernate3, yes.

It should be fairly easy for you to fix that on your side. Reporting that as an issue would a good thing as well.
