Creating a Message interface without using a WSDL.

Hi all,

I am working on a HTTP -> XI -> SOAP synchronous scenario. I dont have a WSDL of the Webservice I intend to use.

Generally, we import WSDL and create an External definition of the same and use in the message interface.

How do i create the inbound message interface without using WSDL?

I want my SOAP message to contain SOAP header and SOAP body.

Kindly provide links of blogs (if possible) for easy understanding

Many Thanks,

Neha
