Hi Benjamin,

If you use IN_OUT synchronous web service invocations (where a single transport connection is used for request and response) we can assume that the order is the same as the order that we invoke web services. However it the IN_OUT web service is invoked using asynchronous transport (request and response are using different transport connections) then we need reliable messaging to guarantee the delivery as well as to ensure the ordering.

We will have a new release with these soon still not decided when though.

Thanks,

Jaliya

Subject: Reliable Messaging for IN_OUT WS


Hi,

if I would only use IN_OUT Web Services, the ordering of the calls must be always right, regardless of using ws reliable messaging or not. Is this true? I think because of waiting for the return value this is true or are there exceptions where it is not true? Are there arguments for using reliable messaging with guaranteed order for those webservices except because of the delivery assurances (exactly once etc.)?

Another question, when will there be the next version of sandesha supporting at most and at least once?

Thanks for your help,

Benjamin
