RE: [Quickfix-developers] [qfj] Publishing Messages to JMS

[Steve B. <st...@te...>]

Hi Caleb,

If the connection is up, but there's no logged on session would
you expect the behavior to be the same? I was expecting a resend
as well, but I need to look into it further. We should have the
same behavior as the C++ implementation. Are there any acceptance
tests that test this behavior for the C++ engine?

Thanks,

Steve

Is there a resend request after the logon? What is the expected behavior
of FIX when a message is sent before a session has been associated with
a connection? What does the C++ engine do in this case?

The C++ implementation always persists messages first, thereby assigning
them a sequence number, and then sends them (excepting of course resends).

So in the case that the conneciton is down when a message is sent by the
Application, it will be logged and resent as a PossDup once the connection
is re-established.  The Application's first Logon message will have a higher
sequence number (e.g. 2) which will cause the counterparty to request a
resend, at which point the original message 1 will be resent.
