Could not get XAResource from ManagedConnection!

[topicfun]

Hi!

At big load I always got this error message. I can't understand it because I don't use XA datasource only one simple oracle-ds.xml.
The OrderingBackupBean is a simple entity bean.

I have searched via net but I didn't find any solution for it only if the XA datasource is used. (Oracle XA config, pad...and so on).
As far as I see I don't get this error message for all entity beans only some...

Do I need to modify some other xml file in Jboss?

Thanks,
topicfun

Looks like the transactions have timedout and hence MARKED_FOR_ROLLBACK. Later on whenever any operation is done in context of this transaction which is marked for rollback, the exception gets thrown

I have increased the transaction timeout in jboss-service.xml and after I didn't get this error!

this XA resource was very confusing for me... I thought there is some XA datasource is also used beside of my oracle-ds.xml...


Thanks for you answer and for the perfect solution ;-) !!!!

[topicfun]

only one additional question....

I have swiched on the trace for tm but I don't know how I can find out from the localID to which methods it is related in my code???
As far as I know if execution of method begins one transaction instance is created with an unique id....

2006-04-13 13:17:02,366 TRACE [org.jboss.tm.TransactionImpl] Created new instance for tx=TransactionImpl:XidImpl[FormatId=257, GlobalId=iacapp3/5345, BranchQual=, localId=5345]

Thanks,
