MQSeries.net :: View topic - Exception while calling webservice through HttpRequest Node

anilmekala · Posted: Wed Mar 05, 2014 9:10 pm Post subject:

Hi All,

I have created two message flows

1) webservice provider flow

HttpInput --> computenode --> HttpReply

compute node :

CALL CopyMessageHeaders();
-- CALL CopyEntireMessage();
SET OutputRoot.XMLNSC.Data ='newdata';
RETURN TRUE;

2)webservice consumer flow

MqInput -->compute --> HttpRequest -->compute1 --> Mqoutput

I have given i/p message in mqinput node as below :
<HTTPTest>
<URL>http://localhost:7080/svc1</URL>
<InputData>
<Data>Test</Data>
</InputData>
<OutputData>
<Data/>
</OutputData>
</HTTPTest>

in compute node

CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
-- CALL CopyMessageHeaders();
-- CALL CopyEntireMessage();
SET OutputRoot = InputRoot;
SET OutputLocalEnvironment.Destination.HTTP.RequestURL = InputRoot.XMLNSC.HTTPTest.URL;
RETURN TRUE;
END;

compute mode :

localenvironment and message

HttpRequest node :

I have entered

Request message location in tree = InputRoot.XMLNC.HTTPTest.InputData

Response message location in tree = OutputRoot.XMLNSC.HTTPTest.OutputData

compute node1 :

BEGIN
-- CALL CopyMessageHeaders();
CALL CopyEntireMessage();
SET OutputRoot.HTTPResponseHeader= null;
RETURN TRUE;
END;

am getting exception as below :
