Re: [Quickfixj-users] Queuing messages between the sessions

[Christoph J. <chr...@ma...>]

Hi,

this cannot be done in QFJ itself. Unless you never reset the sequence numbers automatically.

Usually this can be achieved by having a sequencing in your stored data as well. When you send out 
messages you store the sent internal sequence "number" (e.g. date plus increasing number).
When the session comes up the next time, you subscribe only the data that has a higher sequence 
number than the one that you already sent out.

A more brute-force approach could be to have your application check if there are still messages in 
the store, waiting to be sent. If yes, store these messages (memory or disk), reset the sequence 
numbers and re-insert these messages into the store.

I'm sure there are also other ways to tackle this.

Regards,
Chris.
