DataSource is XA but Weblogic gives RMI

Question

Hello,
          First, yes I know Cloudscape may not be the best database for production and
          XA, but anyway, I have to use it, and it supports XA.
          Now my question :
          I'm using WLS 6.1 SP1.
          I defined a Cloudscape XA pool which seems to initialize well (the server
          logs shows initial connections creations for the XA pool successfully). For
          this pool, the driver classname I use is COM.cloudscape.core.XADataSource.
          Over this pool I defined a Tx Data Source which some JNDI name, let's say
          "MyXADataSource".
          This works well and I can get and use connections from this "MyXADataSource"
          datasource while I use it as a javax.sql.DataSource (from a BMP for
          example).
          However this DataSource is not XA. I mean that it does not implement
          javax.sql.XADataSource (the concrete class is actually
          weblogic.jdbc.common.internal.RmiDataSource). This is a problem for example
          when a connector (let's say the BlackBoxXA sample connector) tries to use
          this datasource as an XA datasource, leading to a ClassCastException.
          So why the concrete weblogic.jdbc.common.internal.RmiDataSource class is not
          an XA class ? Did I configure something wrong or forget something ?
          Thanks for your help.
          Jérôme.

Thanks Priscilla,
          But, so, why the BlackBoxXA connector tries to cast the datasource it
          lookups to XADataSource ?
