No SOAP Envelope error in SOAP Receiver Adapter

Question

Hello Friends,
Informaiton:-
I have configured one Synchronous scenarion for SAP R/3 to PI 7.1 to Java based web applicaiton.
On the Receiver/Outbound side, i have configured the SOAP Receiver Adapter with the Target URL and SOAP Action.
Outbound and Inbound service interfaces have Request/Response and Fault messages.
Issue:-
While sending the Message, Below error is noticed in ABAP stack SXMB_MONI during the Call Adapter Stage and also in RWB (Channel Monitoring) .
com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.io.IOException: No SOAP  Envelope but 1 {}RESPONSES; HTTP 200 OK
I also found that Request message is not reaching to the Java Web server.
I am taking the Same message Payload (found at Call Adapter Stage) and ussing it in XML Altova SPY Web client tool. There it is running scuccessfully and getting the Response message.
please suggest.
Thanks & Regards

Hi,
Yesterday i consumed the same WSDL file in Altova XML SPY and there it is working, getting the Response.
Now comparing the SOAP Request message reaching to the Third party Web server (which fall within the same Lane network)
from SAP PI and Altova XML SPY tool. I used TCP Gateway for the below scenarios.
(1)First i sent the SOAP message from PI and observed the RESPONSE message without the SOAP Envelope in TCP Gatway Trace and hence i am getting the No SOAP Envelope Error in PI.
(2)I consumed the same WSDLfile in Altova XML SPY and sent the SOAP message, here i got the Proper SOAP Response message and hence success in this case. (Used the same Data Payload as used in point 1)
(3)Now to identify the issue in the SOAP Request message being sent from PI, i used the same SOAP message sent in step 1 here, that means copy the entire SOAP ENvelope from the TCP gateway Trace and pasted it in Alota Spy and sent, there it is found running (got the response message from Third Party server).
One difference i found in HTTP Protocol statements in SOAP Request message in Point no 1 and Point no 2 above.
HTTP Protocols in Point 1 (Through PI).
