The jdbc module is in limbo pending our evaluation of the new standalone JCA. With this week's beta release it gained the ability to do -ds.xml deployments, so we can hopefully now make progress on that eval. If we decide to keep the jdbc module rather than junking it in favor of a TS+JCA bundle then we'll handle this issue as part of the jdbc renovation work that will be needed. Don't expect any changes until 4.14 at the earliest. Meanwhile you could try out the new JCA instead if you like.
