Nothing in JCA ever sets the status of the transaction to rollback only. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/533899#533899] Start a new discussion in JCA at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
