Re: Websphere and Local transactions ..

The LocalTransactionStarted event should only be delivered for the
cci.LocalTransaction.begin(), not the spi.LocalTransaction.begin()
invocations.  From the stack trace below, it shows that your RA is
delivering the LocalTransactionStarted event on the
spi.LocalTransaction.begin() call.  This is not correct.  As far as why the
J2EE RI allows this...  The J2EE RI is not a production-ready
implementation and does not cover all aspects of the J2EE Connector
Architecture specification.

I am having trouble getting a resource adapter to work with IBM Websphere
5.0 with Local Transactions.
I having it working fine with J2EE Reference Impl. However with Local
Transactions, when I try to inform the
ConnectionEventListener that a local transaction has started, it seems to
fail.

From the trace it appears that Websphere's Connection Manager is involving
the ManagedConnection in a local transaction from the start, so when I send
a
localTransactionStarted event, it seems to think there are multiple
resources  .. Is there some setting that makes it not register the MC in a
transaction ?

I have the EJB invoking the Connector. Is this related to EJB setting ?

Has anybody encountered this ?

Thanks in advance,

Madhav
