Error Web Service

Hi All

I am getting following error in Http to Webservice Interface

com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.io.IOException: No SOAP Envelope but 1 definitions; HTTP 200

I have checked the Mapping in the test tab and it is working fine, Cache is updated and I have reactivated all the design and configuration objects.

Regards

Abhishek Mahajan
