Re: [hibernate-dev] OGM on WildFly11 ...
Hi Scott,
I would prefer to have ORM accept instances, and so not need the
bi-directional dependency across modules.
Hibernate OGM already bundles/depends on some ORM classes but it would
be much better for everyone if we could keep flexibility about which
versions exactly.
Regarding 2LC: is the RegionFactory the only thing which is currently
being injected as classname rather than instance?
If so I think this would be acceptable for a first preview version,
but I'd still prefer we could clean that up soon.
In terms of module dependencies: Jipijapa/OGM should depend on a (user
selectable) slot of Hibernate OGM. The Hibernate OGM module will
export the dependency of Hibernate ORM which it targets, so the
Jipijapa/OGM module would not need to depend directly on any ORM
module.
Thanks,
Sanne

Hi,
After our discussion last week about improving OGM use on WildFly (by
adding a Jipijapa integration adapter for OGM), I wanted to share some
feedback.
A few years ago, we decided that having a 1-1 (bidirectional) dependency
between ORM + the Jipijapa adapter was okay. With OGM, we need to
discuss again. I think that our choices are to update ORM properties
that identify class names, to also allow a class instance to be
specified. This doesn't have to be all ORM integration properties but
likely should include the ones currently set by Jipijapa.
hibernate.cache.region.factory_class is currently used by Jipijapa to
specify the name of the cache region factory class name. I think this
implies that the Hibernate ORM classloader will need access to the
Jipijapa supplied class (as mentioned above). Currently, in WildFly 10,
the ORM module (org.hibernate:main) depends on the
org.hibernate.jipijapa-hibernate5:main module to resolve this class.
Some alternatives to changing hibernate.cache.region.factory_class to
allow a class to be specified:
1. OGM could bundle the ORM classes or depend on a duplicate ORM module
(with a dependency on a jipi_ogm module).
2. OGM could avoid using the 2lc on WildFly.
Any preferences or suggestions?
Scott
