It is a kind of request/response scenario. I have written a WS called
ReliabilityService with an operation AddExactlyOnceSemantics which takes
a String as an argument and returns this String again.
This ws is called in a reliable sequence with sandesha.
Why should there be two CreateSequence ?
I've added the full messages of my soap monitor as an attachement.
The relevant part of my server-config.wsdd is attached, too.
Thanks,
Benjamin
Hi Benjamin,
I think you are testing the request/response scenario (echo example)
is this correct?
If it is the case, then there are two create sequence messages that
should appear in your soap monitor.
One going from Client EPM to the server EPM before sending requests
One from Sever EPM to the Client EPM before sending the responses.
Check whether you are capturing all the messages in the communication.
According to your configuration the CreateSequenceResponse for the
first message may come in the same HTTP connection and you may have
missed that in the SOAP monitor. Check this and let me know.
Since we can see a terminate sequence with the correct Sequence ID I
think those two messages corresponds to the first sequence and the
last two corresponds to the second sequence that is used to send the
responses.
Configuring the SOAP monitor to capture all the messages is bit tricky
and we normally use two SOAP monitors to check the request path and
the response path.
Let me know if this is not the case that you are experiencing.
Thanks,
Jaliya

Subject: Sequence Identifier inconsistent?
Hi,
I'm a bit confused about the sequence identifiers and the order my
soapmonitor is showing the messages:
1. a createsequence is sent
2. the message to the called ws is sent with sequence element and
identifier uuid:c12e71a0-4569-11da-84b9-bb6c79ed7b66
3. TerminateSequence is sent with id =
uuid:c12e71a0-4569-11da-84b9-bb6c79ed7b66
4. CreateSequenceResponse is sent with id =
uuid:c2cf9e80-4569-11da-b585-a6cf34b28360
5. SequenceAknoledgement is sent with
uuid:c2cf9e80-4569-11da-b585-a6cf34b28360
According to the specification, the CreateSequenceResponse carries
the Identifier for the created Sequence, but that differs:
c12e71a0-4569-11da-84b9-bb6c79ed7b66 !=
uuid:c2cf9e80-4569-11da-b585-a6cf34b28360
