I'm using Hornetq jca adapter to connect the mdb to queue nodes. Is it because the execption thrown (after attempting to connect to node1) is a system exception that the transaction is set to rollbackOnly? If that is the case is it not possible to send the message to node2 even after getting an exception (while connecting to node1) with the transaction type set to REQUIRED? If I use Transaction as NOT_SUPPORTED or BMT everything works fine but is it not possible with CMT/transaction as REQUIRED? Pls help! I've also attached the log file showing the transaction rollback status before and after exception. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/534124#534124] Start a new discussion in JCA at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
