RE: Apache SOAP Client to MS .NET

[Brian Noyes]

Blair,
Haven't tried it with .NET yet, but imagine it is the same issue as calling
an MSSOAP service from an Apache Client. You need a  return type mapping to
deserialize the result.

Below is the client code for a simple MSSOAP service call. You can probably
try the same thing with .NET and get it working.

Hope this helps.

  // URIs for the service itself, and for the specific action (needs to
match the method)

Subject: Apache SOAP Client to MS .NET



I have been trying to use Apache SOAP classes as a client to a MS .NET
service without much luck.

There are some .NET services listed on the XMethods site (
http://www.xmethods.com), they are: Prasad's Stock Quote Service, Breaking
News Service, and ZipCodes. I have included the code that I have tried to
use for these services.

Because I am new to SOAP, I know I'm missing something trivial but I
just can't see it. Can anyone see where I am going wrong?

Thanks,
