Are you sending the proper XML message (SOAP)? If your message isn't
formatted properly, you will definately get a server 500 error back.
It looks liek you are actually just sending text ("Hi"). That's not a
proper SOAP message. Here is a sample of a SOAP message:
http://www.w3.org/2004/06/03-google-soap-wsdl.html .
I personally much of web services manually because it's just easier to
interop with COM that way.
Here's part of what I do... (also be sure to set your SOAPAction in the
http header!) messageData hold my XML message I'm sending.
ASCIIEncoding encoding = new ASCIIEncoding( );
byte[] buffer = encoding.GetBytes(messageData);
HttpWebRequest myRequest =
(HttpWebRequest)WebRequest.Create(this.EndPoint);
myRequest.Method = "POST";
myRequest.ContentType = "text/xml";
myRequest.ContentLength = buffer.Length;
myRequest.Headers.Add(String.Format("SOAPAction: \"{0}\"",
operationName));
myRequest.Timeout = 10000;
using (Stream newStream = myRequest.GetRequestStream( )) {
newStream.Write(buffer, 0, buffer.Length);
newStream.Close( );
}
HttpWebResponse myHttpWebResponse =
(HttpWebResponse)myRequest.GetResponse( );
string rawResponse =
GetWebResponseString(myHttpWebResponse);
myHttpWebResponse.Close( );
Here is the GetWebResponseString method...
private static string GetWebResponseString(WebResponse
myHttpWebResponse) {
StringBuilder rawResponse = new StringBuilder( );
using (Stream streamResponse =
myHttpWebResponse.GetResponseStream( )) {
using (StreamReader streamRead = new
StreamReader(streamResponse)) {
Char[] readBuffer = new Char[256];
int count = streamRead.Read(readBuffer, 0, 256);
while (count > 0) {
String resultData = new String(readBuffer, 0,
count);
rawResponse.Append(resultData);
count = streamRead.Read(readBuffer, 0, 256);
}
}
}
return rawResponse.ToString( );
}
Look closely at what is returned. You may actually be getting the
reason for the fault in the message.
Also, if all is successful, you will get an XML message back. Are you
prepared to parse it?
You may want to actually use the .NET web service mechanism if you
don't want to do everything manually. Since you aren't using the .NET
web service mechanism the web.config configuration doesn't apply.
If you are intending to use .NET for web services, then all you have to
do is add the WSDL file as a web reference and use it as though it were
local. There's not really much work to it. If that is the case then
everything I said above is void, since this is the manual way to do it.
