This sounds like Broker to me, so moving it to that forum...

Do you have a coach or mentor on your site? Have you read the InfoCentre? Have you attended the required training?
Your question is a basic question answered in all these other forums. This forum is generally used by people who get stuck on a particular problem after having attended the training or read thoroughly the InfoCentre.

Hello Pallavi,
Here is the code:
Before the soap request Node write this part of code in compute node:
| Code: |
SET Environment.RequestRecords = CARDINALITY (InputRoot.SOAP.Body.Records[]);
WHILE ( Environment.RequestRecords > 0 ) DO
SET OutPutRoot.SOAP.Body.Address = SET InputRoot.SOAP.Body.Address[Environment.RequestRecords];
PROPAGATE;
END WHILE;
RETURN FALSE; |
After the soap request node, write this part of code in compute node:
| Code: |
IF (Environment.RequestRecords > 0) THEN
SET Environment.address[Environment.ResponseRecords] = InputRoot.XMLNSC.address;
SET Environment.RequestRecords = Environment.RequestRecords - 1;
SET Environment.ResponseRecords = Environment.ResponseRecords +1;
END IF;
IF (Environment.RequestRecords = 0) THEN
DECLARE NEXT INTEGER 1;
SET Environment.ResponseRecords = Environment.ResponseRecords - 1;
WHILE ( Environment.ResponseRecords > 0 ) DO
SET OutputRoot.XMLNSC.address = Environment.address[Environment.ResponseRecords];
SET Environment.ResponseRecords = Environment.ResponseRecords - 1;
SET NEXT = NEXT + 1;
END WHILE;
PROPAGATE;
END IF;
RETURN FALSE;
END; |
Hope this will help you to call service multiple times through loop.
Good Luck |

This is hardly the solution as the message tree is not reset before every call and therefore has extraneous elements in it left over from previous iterations.

It's also not using the right way to access the next child of the response set. You should always code using references rather than [ indexVariable ] syntax.
always.
No, really. Always. |
