Error while testing File-PI-SOAP interface

Question

Dear All,
We are working on File-PI-SOAP interface in which we have exposed a functional module from ECC server as receiver webservice. When we are testing the the interface we are getting following error :
Delivering the message to the application using connection SOAP_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.io.IOException: invalid content type for SOAP: TEXT/PLAIN; HTTP 407 Proxy Authentication Required.
In the receiver SOAP communication channel we have provided the required ECC login & proxy authentication credentials and also we are able to open the URL from PI server. Kindly let us know what more settings are required o make this interface running.
Regards,
NJ

Hi,
This is a synchronous interface and I want to send the output from webservice as a file to third party system.
We are just working on a demo interface, so we have created a webservice of a function module of ECC and also our interface is File-PI-SOAP.
We have also given the login credentials for proxy authentication but still we are getting the error the
SOAP: error occured: com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.io.IOException: invalid content type for SOAP: TEXT/PLAIN; HTTP 407 Proxy Authentication Required
Kindly let us know, how can we resolve this error.
