Guys,
I have searched the developerworks website, this site and looked through the Message Broker samples.
I need a sample flow that uses a Soap Input Node, transforms the Soap message into a Cobol Copybook, putting the message on MQ, and then getting the correlated response from MQ, responding back to the Requestor.
I have configured a similar flow, but I am having trouble configuring specifically the MQGet node to get the response from MQ. This is what I have:
SoapInput-->Compute-->MQOutput-->MQGet-->Compute-->SoapReply
The thing is - we have done a flow that exposes a Web Service in Broker and then doing a SoapRequest to Host, but we need to look at other alternatives, i.e. Copybooks with MQ as a transport protocol to Host.
Any assistance or sample would be greatly appreciated. |

No i dont have the sample... but just want to mention a point since you having trouble in getting response using MQGet.. 
is your MQOutput and MQGet using same queue??
if yes then have you taken the transaion factor into account...

Thanks for the prompt reply.

Yes

I have the following properties on my MQGet Node:
Advanced:
Transaction Mode: Yes
Generate Mode: LocalEnvironment and Message
Copy Message: Copy Entire Message
Copy Local Environment: Copy Entire LocalEnvironment
Request:
Get by correlation ID: Checked
Result:
Output data Location: OutputLocalEnvironment
What I am trying to achieve is to get the correlated reply from Host to format the Soap Reply back to the requestor. |

Apologies, I lied... 
I have a remote queue I put to and I read from a local queue...
So it is like this:
SoapInput-->Compute1-->MQOutput(remote definition)-->MQGet(local definition)-->Compute2-->SoapReply
all of the above nodes connected in a single flow.
Also, in my compute1, I set a correlation ID and try to Get the message from the Local queue by this Corellation Id. |

What about MQOutput node??
What value does it hold for transaction mode..
are you getting no message found error ??

I have an MQOutput node - connected to the input terminal of the MQGet.

Transaction Mode is set to 'Yes' on the 'Advanced' tab

No, I get the exact same message that I put to the output queue. |

Set Transaction Mode to 'NO' since you want MQOutput to commit the message the moment you place it in queue....

Nope. Same thing.
(hey... thanks for your patience - I really appreciate it!)
I have to following configuration settings on my MQGet Node:
Basic: <My Local Queue Definition>
Input Message Parsing: <My message definition of the expected Cobol Response from Host>
Advanced:
Transaction Mode: Yes
Generate Mode: LocalEnvironment and Message
Copy Message: Copy Entire Message
Copy Local Environment: Copy Entire LocalEnvironment
Request:
Get by correlation ID: Checked
Result:
Output data Location: OutputLocalEnvironment
Include message contents in output message assembly: Checked
I guess what I would like to achieve is to set a correlation ID on the message I post to Host and Get the response from Host on a different queue by Correlation ID. |

You must be populating this correlation id in local env too?? for MQGet to know... rt ?
Just asking this since i dont see a compute node after MQOutput to populate this and hence may be you missed this..

Ok, it feels like I'm getting a bit closer now. What field exactly would I be setting in the Environment tree? And how do I tell my MQGet node to use this specific value?
What I'm attempting now is to set the Correlation ID in my ESQL Node preceding the MQOutput Node:
SET OutputRoot.MQMD.CorrelId = '123'; |

I would advise you to pls read about MQGet node in infocenter... You yourself ll be able to answer all your queries..

AkankshA,
Thanks a lot for your assistance - I worked through the samples and the docs and I got it working. I think my biggest mistake was that I set the MQGet property 'Output data location' to 'OutputRoot.MQMD' rather than to simply 'OutputRoot'. Now I realise there's no way that I would have been able to put the resulting data into an MQMD. 
Again, thanks for your time and assistance!
