Thanks Peter and Toby,
I am still learning this whole JCA spec, so thanks for bearing with me. I
am still bewildered about
one thing:

I meant the ResourceAdapter specific implementation of
javax.resource.cci.ConnectionFactory.
Shouldn't I be able to cast whatever is returned from JNDI to a
javax.resource.cci.ConnectionFactory,
and assume it implements that interface? ie,
--------------- JCA 1.0 Final Public Draft, section
10.5 ---------------------------
// Application Component/Client Code
obtain the initial JNDI context
Context initctx = new InitialContext();
// perform JNDI lookup to obtain connection factory
javax.resource.cci.ConnectionFactory cxf =
(javax.resource.cci.ConnectionFactory)initctx.lookup("java:comp/
env/eis/MyEIS");
javax.resource.cci.Connection cx = cxf.getConnection();
----------------------------------------------------------------------------
----------
The fact that JdbcDataSource does not implement the ConnectionFactory
interface is what I do not understand.
