Gettransportinfo in the webMethods 601 version

I am facing probelm to get the required protocol when I use gettransportinfo in the webMethods 6.0.1 version.
My problem Is - I created FTP port,This has enabled and given access mode.I created a service which consists of savepipelinetofile,restorepipelinetofile and gettransaportinfo service.I have submitted the files using WS_FTP exe to the this service.When I went to debug mode for this service, I am getting always HTTP protocol instead of FTP in the pipeline out of getTransportInfo service.

Could any body pls try to solve this probelm or Whether I went in the wrong direction.I am sure this is working in the 4.6 version but unable to do in the 6.0.1 version.
