JPA without persistence.xml using WF 37.0.0.Beta1Preview

[Carla M.]

Hi all!

as I understand, WF 37.0.0.Beta1 Preview provides initial support for Hibernate 7.

Is it possible to use this version to try JPA without persistence.xml ? ( should be possible in Hibernate 7)

Thanks!

Carla

Hi Carla,

It should be possible to try but I haven't yet, perhaps others have?  Some related links:

Let us know if it works or not for you.
