I've added a bug report to check into this. The full-custom JCA
configuration in Resin needs a cleanup (e.g. integration with CanDI
and upgrade to JCA 1.6). Some notes below.

This just means it's stored internally. For full JCA configuration,
you can use Resin's <connector> configuration, although I think it
expects a resource-adapter class.

Unfortunately, <bean> doesn't know about JCA. It's just a straight
instantiation of the class, so it wouldn't create the connection
factory properly.
The <resource> should hook into JCA.

That sounds like a bug in Resin. <resource> should know about JCA.

This should work if the JCA connection factory is a JDBC driver. It
sounds like it's a custom interface, so it won't match.

The full configuration should be the <connector> and <connection-
factory> (in this specific example, <resource> should also work.)
(I'll need to look at this later. It's been awhile since I've looked
at JCA.)
