[jboss-dev-forums] [Design of JCA on JBoss] - Re: JBossTS/JBossJCA XA/Local transactions

[weston.price@jboss.com]

The problem as I see it is in terms of the types of configurations/deployments we have today. Unfortunatley, the use of multiple 1PC resources in JBoss is quite common, in fact, I would go so far as to assert this is the *main* type of configuration we see in client deployments. 

This is especially true in the area of JMS where the underlying provider is not required to support XA. Further, there are a variety of JDBC resources (some of the more off beat ones) that don't provide XA adapters either. 

If we are indeed saying that we no longer support this, or at the very least, it is not supported with JBossTS then we have a real 're-education' situation on our hands. This is independent of what is *correct* being that we provided this behavior before no matter how broken it may have been.

 Again, the cost thing is a factor as well. In many situations, XA costs and many times this does not come cheap. Of course they always have the option to use JBossTM, but I don't think we want to be in the business of recommending this.
