Issue with consuming an external webservice

I’m trying a scenario in SAP PI to consume an external web service :  http://www.webservicex.com/globalweather.asmx?WSDL

SAP ECC <--->PI  <-----> external web service.

Created all the ESR and IB configuration in PI. I'm on PI 7.3 java stack only.

Steps I have followed:

  1) Import  third party WSDL as external definition in the ESR

  2) Created inbound interface based on External message types

  3) Created Data types/Message types and Outbound interface

4) Created Message mapping and operation mapping

  5) In Integration builder created Comm channel for  SOAP receiver

  6) created communication component and CC for ECC system for SOAP sender.

  7) created integrated configuration using the interfaces, comm channels and operation mapping

Now when I go to my ECC system, generate the proxy and try to execute, I’m seeing an error “PARSING.GENERAL”.

This is the error in message log in PI.

Even the payload is blank

Please help !!

Thanks in advance.
