Hi,
I have created a sample message flow in WBI 6.0
HTTPInputNode --> Trace Node --> ComputNode --> TraceNode --> MQOoutputNode.
When I put a message through URL from HTTInput Node, it is coming to MQOutputNode (defined queue), with zero length message.
I am using below code:
CALL CopyMessageHeaders();
-- Output is MQ, so remove HTTP headers
SET OutputRoot.HTTPInputHeader = null;
-- Add an MQMD
CREATE NEXTSIBLING OF OutputRoot.Properties DOMAIN 'MQMD';
SET OutputRoot.MQMD.StrucId = MQMD_STRUC_ID;
SET OutputRoot.MQMD.Version = MQMD_CURRENT_VERSION;
SET OutputRoot.MQMD.MsgType = MQMT_DATAGRAM;
SET OutputRoot.MQMD.Format = MQFMT_RF_HEADER_2 ;
SET OutputRoot.XMLNSC = InputRoot.XMLNSC;
MbElement mqmd = outRoot.getFirstChild().createElementAfter("MQMD");
mqmd.createElementAsFirstChild(MbElement.TYPE_NAME_VALUE,"Format","MQSTR");
RETURN TRUE;
END;
CREATE PROCEDURE CopyMessageHeaders() BEGIN
DECLARE I INTEGER 1;
DECLARE J INTEGER CARDINALITY(InputRoot.*[]);
WHILE I < J DO
SET OutputRoot.*[I] = InputRoot.*[I];
SET I = I + 1;
END WHILE;
END;
CREATE PROCEDURE CopyEntireMessage() BEGIN
SET OutputRoot = InputRoot;
-- SET OutputRoot.XML.A.MessageID = CAST(InputLocalEnvironment.Destination.HTTP.RequestIdentifier AS CHARACTER);
END;
Please let me know, where I am doing mistake?
I appreciate your help.
Regards,
Ramesh |

You're setting the MQMD format to indicate an RFH2 header, but don't set up an RFH2 header.
You're creating a copy of the message of the XMLNSC Domain, then creating a string message after the MQMD. In an interesting way.

Even, after removing those ESQL code also, I am facing same problem.
this is comput node ESQL code:
********************************************************
CALL CopyMessageHeaders();
-- Output is MQ, so remove HTTP headers
SET OutputRoot.HTTPInputHeader = null;
-- Add an MQMD
CREATE NEXTSIBLING OF OutputRoot.Properties DOMAIN 'MQMD';
RETURN TRUE;
END;
CREATE PROCEDURE CopyMessageHeaders() BEGIN
DECLARE I INTEGER 1;
DECLARE J INTEGER CARDINALITY(InputRoot.*[]);
WHILE I < J DO
SET OutputRoot.*[I] = InputRoot.*[I];
SET I = I + 1;
END WHILE;
END;
CREATE PROCEDURE CopyEntireMessage() BEGIN
SET OutputRoot = InputRoot;
END;

I'd suggest thinking about what the code is doing, rather than randomly experimenting.
Consider your latest code fragment, which makes no attempt to set up a message body of any kind. Why are you puzzled that there's no output message?
It also sets up an MQMD, but doesn't populate it with any values; this is not going to help.
