I am receiving the generic OracleXAException, XAException.XAER_RMERR, when
trying to connect to multiple Oracle XA Datasources (Oracle version 10.2.0.2)
within the same transaction. I have tried several different approaches to
create the Oracle XA Datasources, including the thin driver, oci, oci8, and
tns. I have followed the advice on the JBoss Wiki to add the following to the
xa-datasource:
<track-connection-by-tx/>
<isSameRM-override-value>false</isSameRM-override-value>
<no-tx-separate-pools/>
I have tried enabling Pad for the org.jboss.tm.XidFactory and that doesn't seem
to work.
I have verified with our Database Administrator that XA is enabled for Oracle
10.2.0.2, JAVA_XA packages are visible, and so is the DBA_PENDING_TRANSACTIONS
view.
I have tried to run the code below using JBoss 4.2.0-GA and 4.2.0-CR2.
Anyone have any thoughts or run into this issue?
Thanks,
Dave

Application code:
Inside a Servlet, JSP, or EJB, create a UserTransaction or let the container
create the Transaction, and then get two connections, one from each database,
and issue simple queries.

getInitialContext().lookup("java:comp/UserTransaction");
utx.begin();
Connection conn1 = getConnection1();
