Hi Marwa,
can you provide an outline of your code please for better understanding?
Also provide the error messages if there are any?
You can try the following:
In your provider webservice invoke a regular flow service (independent from the webservices/WSDLs, but it can be located in the same package) in which you can invoke the consumer werbservice.
Regards,
Holger
