Anyone successfully using WL 6.0 and oracle.jdbc.xa.client.OracleXADataSource?

Question

My final goal is to have two xa pools pointing to different db's and
have them in the same user transaction and do a 2 phase commit. I
can't get past connecting to a single xa datasource. I have "Grant
Select on DBA_PENDING_TRANSACTIONS to public".
My config.xml snippet:
<JDBCConnectionPool
Name="ModelXaPool"
Targets="WebApp"
URL="jdbc:oracle:thin:@SERVER1:1521:DB"
DriverName="oracle.jdbc.xa.client.OracleXADataSource"
InitialCapacity="2"
MaxCapacity="10"
CapacityIncrement="2"
Properties="user=uid;password=pw"
RefreshMinutes="10"
/>
<JDBCTxDataSource
EnableTwoPhaseCommit="true"
JNDIName="ModelManagerTxDataSource"
Name="ModelManagerTxDataSource"
PoolName="ModelManagerXaPool"
Targets="WebWORKS"
/>
My code snippet:
UserTransaction tx = msgCtx.getUserTransaction();
tx.begin();
java.sql.Connection conn =
(DataSource)ctx.lookup("ModelManagerTxDataSource")).getConnection();
Statement stmt = conn.createStatement();
The connection seems to be gotten just fine. On the createStatement,
I get the following exception.
java.sql.SQLException: Internal error: Cannot obtain XAConnection
Creation of XAConnection for pool ModelXaPool failed after
waitSecs:298
at weblogic.jdbc.jta.DataSource.refreshXAConnAndEnlist(DataSource.java:772)

Any suggestions/advice?
Thanks,

Hi Dale,
What version of Oracle are you using at least 8.1.7 is need to be able to
use Oracle thin driver/XA. Also the JDBCConnectionPool and TxDataSource tags
dont seem to match here. Both need to be targeted on to the same server. And
the name of the pool in TxDataSource need to match the pool you have on the
server.
To setup oracle for XA you need to make sure this script is run on the
server, initjvm.sql (It should be in your oracle installation rdbms scripts)
and then grant select permission on dba_pending_transactions.
Are you able to setup a connection pool with a non-XA driver?
