Global transaction problem with JDriver/Oracle and Oracle XA

Question

We are haveing serious problems with Container Managed Transactions on Bea 6.1
and Oracle with EJB having set "Required" for all methods. We have tried in vain
to make it work with JDriver as well as OracleXAClient. Both fail at sometime
during the execution throwing "Not called in cotext of global transaction" (with
JDriver) OR "XAER_PROTO : Routine was invoked in an
inproper context start() failed on resource 'OracleXAPool'" (this one with oracle
XA).
1.) Weblogic JDriver-XA:
DatabaseMetaData metaData = dataSource.getJDBCConnection.getMetaData();
ResultSet resultSet = metaData.getTables(null, null, tableName.toUpperCase(),
new String[]{"TABLE"});
This fails immmediately saying that it was not called from global transaction.
Interesting thing is that with OracleXA, it doesnt say this exception at this
check point.
2) Oracle XA
Okie, we couldnot read through the CLOB using it so for reading CLOB, we used
direct jdbc connection and then did away with it. Now all next sql queries were
executed against oracle pool using XA data source with OracleXAClient. But at
some point we again ran into the problem "XAER_PROTO : Routine was invoked in
an
inproper context start() failed on resource 'OracleXAPool'"
3 Oracle Thin Driver
everything always works with it.

Answer 1

AFAIR this issue was resoved by moving tx opreations out from non-tx
methods.

Jawad,
It would be nice if you can post the full stack trace error message. Didyou try moving to
the latest service pack (sp2) for WLS6.1.
Thanks,

Yes we had correctly set TXDataSource and let it to point to the right
connection
pool each time and it worked well with oracle thin driver but not whenwe switched
the pool to JDriver or OracleXAClient. Note that we could aways confirmthat pool
was successfully created alongwith we could retrieve connection from itvia TXDatSource,
things gave problem after we attempted to do what i had mentioned in mylast posting.

Also with JBoss 2.4.4 things work pretty well. So couldnt be our codeproblem.

Jawad,
Did you set up TxDataSource?
