Subject Re: camel-smpp in trx mode
Date Sun, 13 Jan 2013 11:01:41 GMT
Yes, it's possible to share the jsmpp session, btw. we have to share it in
this case (only one TRX connection is allowed).
We could only log the received message, if no consumer route is defined.
But may be this is not suitable for most of our users.
We could also throw an exception at route/context start up, but this is not
right in my opinion. Assume you do not expect to receive short message (you
only send short message) and you send the messages with the flag that you
are not interested in any delivery received message (part of the SMPP
specification). In this case, you do not need a consumer route.

The best solution I can think for this case (TRX mode connection and no
consumer route) is to log the incomming message at WARN level (delivery
receipt, short message, ...) and reject it. Than the SMSC should try to
redeliver the short message at a later time and the user can fix this
misconfiguration. What do you think?

Best,
Christian
