Hi all,
I am facing a problem while trying to reply to the originator using HTTPInput and HTTPReply node. Can anybody help to resolve the case ?

Exception: "need return context info"

I have checked the immediate message tree before HTTPReply and saw that OutputLocalEnvironment.Destination.HTTP.RequestIdentifier is being populated fine.


Flow Part 1:
HTTP Input -> Compute(RemoveHTTPINputHeader)->MQHeader(Add MQMD Header)->MQOutput(input to 3rd party app)->Compute(saving MQMD and RequestIdentifier)->MQOutput(say Queue 'xxx')


Flow Part 2:
MQInput(reply from 3rd party)->Compute->MQGet(get msg from queue'xxx')->Compute( a:Setting RequestIdentifier by previously saved copy b: creating OutputRoot.BLOB.BLOB)->HTTPReply

You need to deploy both flows in the same EG.

Not necessarily true for HTTP nodes. If HTTP nodes are using the External (broker wide) listener (which is the default) then they can be in different execution groups, but have to be in the same Broker. Post the output of a trace node immediately after the HTTPInput node and immediately before the HTTPReply node both showing the LocalEnvrionment.

Kind regards,

Except for the part where this particular flow saves stuff between message flow invocations... if it's being saved using shared variables...
