A jdbc transaction error occur

Question

Hi Everybody
A jdbc transaction error occur when I deploy the application on the server .
Below is the stack trace
#SAP J2EE Engine JTA Transaction : [03bfffffffd3a000ffffffc0]####Application [13]##0#0#Error#1#/System/Audit#Java###Exception #1#com.sap.engine.services.dbpool.exceptions.BaseSQLException: Cannot commit transaction from this connection of "YTSQLS2K" DataSource. This resource participates in a local or distributed transaction.

This resource participates in a local or distributed transaction.
Any idea about it
I use the jdbc version in datasource <jdbc-1.x>
is there a need to replace it with <jdbc-2.0>
Thank You

Hibernate allows you to choose transaction manager. As Nikolay pointed out, in a JEE envirnment it's prefferable to use JTA transactions. All you need to do is to configure hibernate to use a JTA transaction manager. It is all written in the Hibernate documentations. See
http://www.hibernate.org/hib_docs/v3/reference/en/html_single/#configuration-j2ee
and
http://www.hibernate.org/42.html#A5 .
The relevant properties that need to be set in the configuration are:
hibernate.transaction.factory_class=org.hibernate.transaction.JTATransactionFactory
and
hibernate.transaction.manager_lookup_class=<Class that knows how to lookup>
You need to implement a class that knows how to lookup user transaction in SAP J2EE Egnine.
The class must extend org.hibernate.transaction.JNDITransactionManagerLookup and only override its abstract method getName (simply returning the lookup string). Then provide the fully qualified name as value of the property and make sure that Hibernate can load the class.
That should work.
