Can't we publish to a topic directly from HTTPInput node?
From what the doc says, looks like we cannot.
But can we do something like, HTTPInput -> Compute -> MQOutput -> Compute -> Publication
| Quote: |
The input node might be one of the following built-in nodes:
An MQInput node which represents a WebSphere MQ queue
A Real-timeInput node which receives messages from a JMS application using WebSphere MQ Real-time Transport
SCADAInput which represents a SCADA input port

You should be able to publish from an HTTP Input node just fine.
You'll just need to construct an MQMD and an MQRFH2.

I am not able to do it.
My first flow had
HTTPInput ->Compute -> HTTPReply
---------------> Compute2 -> Publication
But it is not publishing.
The ESQL I have there is:
| Code: |
SET OutputRoot.HTTPInputHeader = null;
CREATE NEXTSIBLING OF OutputRoot.Properties DOMAIN 'MQMD';
SET OutputRoot.Properties.MessageFormat = 'XML';
SET OutputRoot.MQRFH2.(MQRFH2.Field)Format = 'MQSTR ';
SET OutputRoot.MQRFH2.psc.Command ='Publish';
SET OutputRoot.MQRFH2.psc.Topic = 'News/India'; |
The same code works for simple pub sub using MQInput node. |

I take it back.
I could do it.
I had to comment the copy messaqgeHeaders and this line in my ESQL

| SET OutputRoot.HTTPInputHeader = null; |

So, just to verify - you commented out the call to copyMessageHeaders, and commented out the line that erased the HTTP header.
So, basically, you built the entire output message from scratch.
