Cloudscape-Weblogic XA mismatch

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.

Hello Slava,
Thank for your reply.
However as I said, this remains a problem when the BlackBoxXA connector
tries to use this datasource as an XA datasource, because its implementation
does an explicit cast to XADataSource (leading to a ClassCastException).

Hi,
When you lookup for a datasource, you get an object
implementing DataSource interface, not XADataSource.
You don't have to cast it to XADataSource. If you need
XA behavior, all you need is setting up a TXDataSource
with a driver implementing XADataSource. weblogic will
take care about the rest.
