Thanks, I know

Yes you are right, auto commit has no means for jta connection and cannot be
set to true; here I just set auto commit to false, so a jta connection
should just omit it;
But the surprise thing is if I doesn't affect auto commit state(in the
program, just comment the statement "setAutocommit(false)"), when execute
database operation,  a "ORA-02089: COMMIT ..." exception  will be throwed by
oracle's database driver; it looks like the Geronimo does a wrong things
"commit on the connection when execute database operation"; and this should
only occurs on non-jta connection, because only no-jta connection will set
auto commit default to true.

The datasource  is org.tranql.connector.jdbc.DataSource. And it use  a  a
managed-connection factory " org.tranql.connector.oracle.XAMCF" to open
connection; And the managed-connection factory use a oracle's xa datasource
(oracle.jdbc.xa.client.OracleXADataSource);

By the way , I haven't ever post a trivial problem I have meet when I deploy
the Oracle-XA data source. The trivial thing is: I must change the deploy
plan created by Geronimo's web manage console tools,   delete the empty
property "TNSEntryName" and manually deploy it; because this is the oracle9i
database driver's question --- "a empty string value(not a null value) set
to TNSEntryName" will cause oracle9i's database driver to omit the other
property (etc serverName, serviceName ...) and cannot establish a connect ; 
I thinks this should have no means to the transaction commit failure; but
maybe it would give some other useful things help to find out the reason.

Thanks a lot

In the future it would be great if you could only post to one mailing  
list.

I'm not sure what is wrong yet, however you should never try to set  
the autocommit state of a connection that is enlisted in a jta  
transaction.  Enlisting and delisting the XAConnection will result in  
the autocommit being dealt with properly.  The value from  
getAutoCommit may or may not be meaningful in a jta transaction.   
Outside a jta transaction the autocommit state defaults to true.  I'm  
quite surprised you didn't get a more informative error.

One important piece of information that I don't see is which tranql  
wrapper you used to deploy your datasource.

thanks
