Two Oracle XA connections fails

Question

We experience problems when using more than one Oracle XA-resource from inside an EJB context under WSAD 5.1.
It looks like the Oracle jdbc-driver isnt XA-complient with itself ;)
We use the following configuration:
- Oracle9i 9.2.0.3
- Oracle9i_9.2.0.3 jdbc-driver,
- WSAD 5.1
- JDBC provider type=Oracle JDBC Driver (XA)
- One statelsss SB
- Two Oracle XA datasources
The following code is run inside the SB:
Context ctx = (Context) new InitialContext().lookup("java:comp/env");
DataSource ds1 = (DataSource) ctx.lookup("jdbc/ds1");
Connection conn1 = ds1.getConnection();
Statement stmt1 = conn1.createStatement();
stmt1.executeUpdate("insert into test (test) values('test')");
DataSource ds2 = (DataSource) ctx.lookup("jdbc/ds2");
Connection conn2 = ds2.getConnection();
Statement stmt2 = conn2.createStatement();
stmt2.executeUpdate("insert into test (test) values('test')");
// Fails on SB exit with the following in the server log:
[18.09.03 20:45:06:174 CEST] 4887ae48 WSRdbXaResour I
The XA Error is : -3
The XA Error message is : A resource manager error has occured in the transaction branch.
The Oracle Error code is : 2051
The Oracle Error message is: Internal XA Error
[18.09.03 20:45:06:189 CEST] 4887ae48 WSRdbXaResour W DSRA0302E: XAException occurred. Error code is: XAER_RMERR. Exception is: <null>
And the client experience this exception:
javax.transaction.TransactionRolledbackException: CORBA TRANSACTION_ROLLEDBACK 0x0 No; nested exception is:
     org.omg.CORBA.TRANSACTION_ROLLEDBACK: javax.transaction.TransactionRolledbackException: minor code: 0 completed: No
A similar problem have also been posted on an ibm forum: http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&threadm=bk4tfn%2499n8%241%40news.boulder.ibm.com&rnum=1&prev=/groups%3Fq%3D2051%2BInternal.XA.Error%26hl%3Den%26lr%3D%26ie%3DUTF-8%26oe%3DUTF-8%26selm%3Dbk4tfn%252499n8%25241%2540news.boulder.ibm.com%26rnum%3D1

We will appreciate any workaround for this problem. Is it a oracle driver problem?
