Re: [teiid-dev] Teiid dialect in Hibernate
My understanding of how things work (from just tinkering with it) is that the dialects are
delivered with Hibernate (in the hibernate3.jar). Ours it not, which is what I'm
asking opinions on.
Hibernate Tools requires you to configure a Hibernate installation. I just pointed to my
AS, but you can use a standalone if you want. From there I think the plug-ins load a
static set of jars from the installation you configured. We blow up because the classpath
defined by the plug-ins doesn't contain our dialect.
Mike-I think you could define this as a Tools defect if you say that Tools should allow
you to add a dialect.
Ramesh-The drivers are supplied by the DataTools ConnectionProfiles and Drivers that you
have to define before you use Hibernate, so drivers are a different issue, and not
something that the hibernate plug-ins have 'built in'. It's an configuration
step that's already extensible in a way that Dialects don't appear to be.
I'm personally in favor of including our dialect in Hibernate because then Tools will
just work, there won't be some additional step for Teiid. It seems to me that if
Oracle just works out of the box in Tools, then a fellow JBoss project should just work.
The only downside I can see to including our dialect in Hibernate is that our release
cycles don't match up and changes/maintenance would have to be managed across our
differing cycles.

I do not know whether it makes sense to include or not in the JBoss

think).
How do they handle supplying the Oracle driver by the user? If this a
separate operation too, then you have case to include Teiid Dialect
in
JBDS.

Hibernate in JBoss Tools. In the latest release Hibernate tools added
Teiid as an option in the Hibernate Tools UI. However, the Teiid
dialect is not included in any release of Hibernate, so the Tooling
doesn't work. I'm still looking for a better way, but as of now the
only way I have found to get the dialect discovered in Tools is to put
it in the global classpath.

Hibernate by default in order to ease the path for our existing users
to use other JBoss technologies, as well as easing adoption of Teiid
by existing Hibernate users. Does anyone have an opinion pro or con
about trying to get the Teiid dialect into Hibernate?
