The request failed with HTTP status 405: Method Not Allowed.

I have a super simple webservice that was compiled using gsoap with C++, i'm trying to get it to work and be consumed withing a VB.NET web app.

Is there some import that I need if the webservice is not of MS? I have referenced it fine with no apparent errors. It's comprised of a WSDL file and an EXE.

Please help?!
