Hi,
Could any one help me out on how to add a http header from MQ message. Iam using Msg broker 6.1 version. my flow
HTTPInput -> Compute1 -> MQ-Output -> Compute2 -> HTTPReply
I have placed the trace before HTTPReply to find out why the HTTP Header is not added.
I have copied the snapshot of the code what I have done in Compute2 node to add the HTTP Header and strip MQMD.
CALL CopyMessageHeaders();
-- To generate the HTTP Reply message for the MQ
SET OutputRoot.Properties = InputRoot.Properties;
SET OutputRoot.MQMD = null;
SET OutputRoot.Properties.MessageDomain = 'XMLNSC';
SET OutputLocalEnvironment.Destination.HTTP.RequestIdentifier =
Environment.Variables.HTTPRID;
-- Env Var HTTPRID contains the Rqst Id of HTTP Input header
SET OutputRoot.XMLNSC = InputRoot.XMLNSC;
But in the trace I am not able to see the HTTP Header details. Pls help me out.
Thanks in advance.

Please make sure that you are passing both LocalEnvironment and Message in your Compute Node 2 Properties.

Hi,
Thanks for the reply. Iam passing both the LocalEnvironment & Message from the Compute2 node.
* If you could see the snapshot of my code sent earlier I have stripped
the MQMD headers, Do I need to add explicitly HTTP Headers.
* Moreover I found in my trace that there were no HTTP Headers and the Reply Identifier value is set to X'000000000000000000000000000000000000000000000000' and not to there environment variable "HTTPRID".
HTTP Reply Node doubt
---------------------------
I have one more clari whether do we need to set explicitly in compute2 node as
SET OutputRoot.HTTPReplyHeader.Host = ’localhost:1234’;
or
Click the Generate default HTTP headers from input or response option in the Basic properties of HTTPREPLY node
for Reply purpose.

In this message flows design can you please let me what will happen when a webserivce is not available or we get any http errrors.
Is this message flow capable of sending the standard reply back for http errors or only an OK reply back as acknowledgement.
I am having a simliar message flow design.
Thanks in advance.

Why don't you use the sample flows and see for yourself?
You will learn far more from that than just asking questions here. If you do run into problems then you will have a better point to start from when asking questions here.
A good tip is to modify the flows and put trace nodes everywhere. Then the output will show you in all its gory details the passage of the massage through the flow and importantly, the structures in the various folders at critical points in the flow.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Davies,
I am getting a time out error when the message flow is down from aclient.
200 OK response for a sucessful response.
Can you please let me know how to create http error scenario?
I was not able to test this so I asked this question.

Disable the service that you are talking to. That will give you an error.
Alter the client to try to talk to a non existent page
