Reliable message queue?
Hi, As far as I can understand, Kannel's current implementation of outgoing and incoming SMS queue is internal and implemented using the List structure of gwlib. This is not good, we can't safely restart processes this way because it would lose any data in the queue. I'm wondering if we could implement a MySQL and/or PostgreSQL based SMS queue, providing a reliable storage to preserve data between sessions. Just like the DLR code, we would need an abstraction over the real backend doing the dirty job; to provide a unified interface to the current queue code, I guess. Nothing trivial, but do you think it's worth having this? -HAND -- Enver ALTIN |http://skyblue.gen.tr/ Software developer @ Parkyeri | http://www.parkyeri.com/ signature.asc Description: This is a digitally signed message part

Maybe I could salvage the better one from NMGW some day. And in any case, push message can be lost if it is 'in air' between smsbox and bearerbox unless my patch is applied) -- &Kalle Marjola ::: Development ::: Helsinki ::: Enpocket

There are commercial products that allow you invoke Java APIs from C code.
