Hi all,
I'm pleased to inform you that we have just started working on STOMP protocol implementation in erlang programming language. We aim to create both client and broker/server using pure erlang/OTP. If anyone would be interested please visit following pages: http://groups.google.com/group/erlstomp http://code.google.com/p/erlstomp http://www.erlang.org/pipermail/erlang-questions/2007-September/029075.html Take it easy, Tom --------------------------------------------------------------------- To unsubscribe from this list please visit: http://xircles.codehaus.org/manage_email |

Hi,
I've been thinking about transactions in STOMP and I need some clarification on that. I've been working on the implementation of server/broker in erlang. Case 1. I have client A, that is subscribed to destination D (ack=auto). I have also client B who sends messages to X. Client A begins transaction T and sends messages M1 and M2 to D in transactional way. They shouldn't be delivered to B unless client A commits transaction T. Once A commits T messages M1 and M2 should be delivered to B in given order. Case 2. Let's consider that destination D is in ack=client mode. Client A sends messages M1 and M2 to D (no transactions). Prior to that B begins transaction T. Both M1 and M2 are delivered to B but the server expects to get acknowledgment. Client B sends these for M1 and M2 and then aborts transaction T. What should happen then? Should we keep messages on the server until ACK will arrive from B or B disconnects? Is it OK if I say that transaction is part of the client session? Even both client A and B create transaction with the same name they remain distinct and independent, don't they?
