David,

I am not yet fully sure of the result from what Blas is suggesting.

But if it results in jdbc support being somewhat separated from the jca
support then that is a big plus for anyone who like us is using the
driver as a standard, basic, boring, traditional JDBC driver and are not
using JCA (because our frameworks don't support it and neither do other
drivers so why change).

So I would support a refactoring that makes it simpler for people like
me to follow where the strictly JDBC elements come from.

I don't know if this repackaging will allow a JDBC driver without JCA
support to be built, I have mixed feelings about that despite not using
JCA at present.

Thanks

Dave
