Hi everybody.

I'm working on C# web services with my french research team, and I've
got some troubles using gmcs & xsp.

When I run my HelloWorld Web Service in xsp2 (service dll was compiled
using gmcs), I've got the following error printed in the web page
(http://localhost:8080/HelloWorld.asmx) :

This web service does not conform to WS-I Basic Profile v1.0
    * R2701: The wsdl:binding element in a DESCRIPTION MUST be
constructed so that its soapbind:binding child element specifies the
transport attribute
          o Binding 'HelloWorldHttpGet', in Service Description
          o Binding 'HelloWorldHttpPost', in Service Description

If I try to build a proxy, using wsdl, no problems. using wsdl2, same
error shoot again :'(

petitroll at bartimeus:~$ wsdl2 http://bartimeus:8080/HelloWorld.asmx?WSDL
Web Services Description Language Utility
Mono Framework v2.0.50727.42
There where some warnings while generating the code:
[same text as above, describing R2701 error]

The same problem append on my iBook and on my Kubuntu :'(.

I'm using the following asmx file :
petitroll at bartimeus:~/HelloWs$ cat HelloWorld.asmx
<%@ WebService Language="C#" Class="Rainbow.HelloWorld" %>
petitroll at bartimeus:~/HelloWs$

And the following code-behind file, compiled by :
gmcs -t:library -r:System.Web.Services \
             -out:bin/HelloWorld.dll HelloWorld.cs

petitroll at bartimeus:~/HelloWs$ cat HelloWorld.cs

    [WebMethod(Description="Say Hello to someone")]
    public string SayHello(string who)
      return String.Format("Hello, {0} !", who);

    [WebMethod(Description="Say Hello to the World !")]
    public string HelloToTheWorld()
      return SayHello("world");

If somebody has an idea ... ^_^
