Re: [weld-dev] persistence and transactions outside Java EE
Yes, I understand the need for XA enlistment, but JBoss Transactions
is already able to do that, right? What I'm saying is that you would
use the TransactionalDriver together with a pool. Or does
TransactionalDriver already do pooling?
Yes, I understand that this is primitive compared to JCA. But we're
dealing with the users who claim they don't want or need an
application server. They, for their own, mostly incomprehensible,
reasons, *want* to use Tomcat or Jetty or something without a JCA
layer, together with one of the very inferior pooling solutions that
are available in that environment. And they've been told for years by
the Spring crowd that it's a good idea and that they should keep doing
it.
Now, you and I both know this to be a total load of bunk, but we have
tried to argue with these people and it is futile. They read it in
books, so it must be true. We all know that a couple of years of
exposure to Spring turns good developers into drooling, brain-damaged
automatons who believe anything you tell them as long as you wave
around enough underspecified jargon like "lightweight" and remind them
how much EJB sucked 5 years ago.
Now, if you know of a good, reasonably easy to use standalone JCA
layer, I'm all ears, but AFAIK, there's nothing really available in
this space.

None of the pools is XA aware - they will pool standard connections, but not
XA ones that need XAResource enlistment to the JTA tx. The
TransactionalDriver in JBossTS will do that, but it's pretty primitive
compared to a real JCA.
