Hi all,
I have a simple message flow which is as follows:
MQInput->Compute->HTTPRequest->MQOutput.
I have given Trace and MQOutput nodes accordngly for the errors, failures and exceptions.
The ESQL in the compute node is as follows:
| Code: |
CREATE COMPUTE MODULE testmsgflow_Compute
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
CALL CopyMessageHeaders();
SET Environment.myMQMD = InputRoot.MQMD;
SET OutputRoot.Properties = InputRoot.Properties;
SET OutputRoot.Properties.MessageFormat = 'XMLNS';
SET OutputLocalEnvironment = InputLocalEnvironment;
-- Create an HTTP header for the message
SET OutputRoot.HTTPRequestHeader.SOAPAction = 'http://tempuri.org/productName';
-- Declare the XML namespaces we will be using
DECLARE mySoapNS NAMESPACE 'http://schemas.xmlsoap.org/soap/envelope/';
DECLARE myNS1 NAMESPACE 'http://tempuri.org/';
DECLARE myXSI NAMESPACE 'http://www.w3.org/2001/XMLSchema-instance';
DECLARE myXSD NAMESPACE 'http://www.w3.org/2001/XMLSchema';
-- Add an XML declaration to the message
SET OutputRoot.XMLNS.(XML.XmlDecl) = '';
SET OutputRoot.XMLNS.(XML.XmlDecl).(XML.Version) = '1.0';
SET OutputRoot.XMLNS.(XML.XmlDecl).(XML.Encoding) = 'UTF-8';
-- Create the SOAP Envelope
SET OutputRoot.XMLNS.mySoapNS:Envelope.(XML.NamespaceDecl)xmlns:"SOAP-ENV" ='http://schemas.xmlsoap.org/soap/envelope/' ;
SET OutputRoot.XMLNS.mySoapNS:Envelope.(XML.NamespaceDecl)xmlns:xsi = 'http://www.w3.org/2001/XMLSchema-instance' ;
SET OutputRoot.XMLNS.mySoapNS:Envelope.(XML.NamespaceDecl)xmlns:xsd = 'http://www.w3.org/2001/XMLSchema' ;
-- Set the operation name and parameters
SET
OutputRoot.XMLNS.mySoapNS:Envelope.mySoapNS:Body.productName.(XML.NamespaceDecl)xmlns:ns1 = 'http://tempuri.org/';
--SET
--OutputRoot.XMLNS.mySoapNS:Envelope.mySoapNS:Body.productName.pdtName.(XML.Attribute)myXSI:type = 'xsd:string';
--SET
--OutputRoot.XMLNS.mySoapNS:Envelope.mySoapNS:Body.myNS1:userName.(XML.NamespaceDecl)mySoapNS:encodingStyle = 'http://schemas.xmlsoap.org/soap/encoding/';
SET OutputRoot.XMLNS.mySoapNS:Envelope.mySoapNS:Body.productName.pdtname= 'Cruise';
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;
END MODULE;

I have hard coded the input value, so it doesnot matter what is the message given to the MQInput node.
I can read the HTTPRequestHeader from the flow which is similar to the format in the SOAP which is as follows:
| Code: |
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<productName xmlns="http://tempuri.org/">
<pdtname>string</pdtname>
</productName>
</soap:Body>
</soap:Envelope>
|
I am getting the exception that the Message doesnt contain a valid MQMD.
The trace after the exception has occured which was caught at the MQInput node is as follows:
| Code: |

If it could help, the input message was
| Code: |
<?xml version="1.0" encoding="utf-8"?>
<productName><pdtname>Cruise</pdtname></productName>

Hi,
Is there an easier way to get the entire exception list without having to copy the individual messages. May be I have not explored into all the features of WBIMB, but if you could help me, I will be able to save some time. I am sorry for this.
Thanks and Regards,
Thripura Sundari |

I am using the following in the trace-node for getting the error-trace in a file:
Trace-Node Properties:
Destination : File
File Path : C:\MyErrorTrace.txt
Pattern:
| Code: |
############### TRACE-START #################
ROOT TRACE:
${Root}
ENVIRONMENT TRACE:
${Environment}
LOCAL ENVIRONMENT TRACE:
${LocalEnvironment}
EXCEPTION TRACE:
${ExceptionList}
############### TRACE-E N D ################## |
Message Catalog : <blank>
Message Number : default value (here I am using 3051)

You're getting the exception because your message does'nt have an MQMD.. Add a compute node after the HTTPRequest that will add the MQMD back to the message before it is put to your Output Queue... Like So... MQInput->Compute->HTTPRequest->Compute2->MQOutput
Here's the ESQL in Compute2:
| Code: |
CREATE COMPUTE MODULE compute2
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
//Copy in the MQMD.
SET OutputRoot.MQMD = Environment.myMQMD;
//Im assuming your message is in the XML Domain.
SET OutputRoot.XML = InputRoot.XML;
END;
END MODULE;
