Hi All,


I am using Broker and Toolkit V 6.1.0.7 for creating a Web Service. Message flow is like
SoapInput->compute1->SoapRequest->compute2->Reply.

I am getting the following error while running the flow

and Message comes out from the Fault Terminal of the SoapRequest node.
Strangely the same flow works in the Broker version of 6.1.0.4. I captured the message going to the SOAP Request node in a Queue. But it had nothing abnormal. Then I commented the copy message header from the compute1. It is working fine now even in 6.1.0.7.

Is it happening because the Properties and http Input header of the SOAP Input are not getting changed according to WSDL defined in SOAP Request node. So if no message headers come from compute1 then SOAP Request node creates the default headers but when it receives the headers it is not replacing them properly?

The error is being thrown trying to process the response.

You need to take a network level trace between the request node and the service being invoked and see if the service you're calling is returning a bad response.

For that do I need to use the net sniffers? We are not allowed to install a sniffer javascript:emoticon('')

How is this related to copy message headers?

You can use TCP Monitor available on on Eclipse. Run the TCP Monitor on a port and route the SoapRequest to TCP Monitor port and see the message exchanged.
