Hi Veronika,
Good to know its working now, did anything change in the setup which might have made this happen...
The exception below is not related to Generic RA at all, its a resource recovery exception for the JDBC callflow pool. Typically resource-recovery happens automatically when the server is started, and would recover any pending/partial transactions for all the connector resources...
