(500) Internal Server Error on IronPython

I tried to use IronPython to create a SOAP request to a Web Service but got an Internal Server Error.

The same script has been tested from C# withouth error. Anyone got a clue?

Following is the ironpython command:

  1: IronPython 2.6 (2.6.10920.0) on .NET 2.0.50727.4927
  2: Type "help", "copyright", "credits" or "license" for more information.
  3: >>> from System.Net import *
  4: >>> from System.Text import *
  5: >>> from System.IO import *
  6: >>> query = Encoding.UTF8.GetBytes('''<?xml version="1.0" encoding="utf-8"?>
  7: ... <soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns
  8: :xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://www.w3.org/2003/05
  9: /soap-encoding" xmlns:tns="http://www.witsml.org/wsdl/120" xmlns:types="http://w
 10: ww.witsml.org/wsdl
 11: ...   <soap12:Body soap12:encodingStyle="http://www.w3.org/2003/05/soap-encoding
 12: ">
 13: ...     <q3:WMLS_GetVersion xmlns:q3="http://www.witsml.org/message/120" />
 14: ...   </soap12:Body>
 15: ... </soap12:Envelope>''')
 16: >>> req = WebRequest.Create("http://localhost:81/Petrolink.Powerstore.Webservice
 17: /wmls.asmx")
 18: >>> req.Headers.Add("SOAPAction", "\"\"")
 19: >>> req.Credentials = NetworkCredential("fred", "derf");
 20: >>> req.ContentType = "application/soap+xml; charset=utf-8"
 21: >>> req.Accept = "text/xml"
 22: >>> req.Method = "POST"
 23: >>> requestStream = req.GetRequestStream()
 24: >>> requestStream.Write(query,0,query.Length)
 25: >>> requestStream.Close()
 26: >>> response = req.GetResponse()
 27: Traceback (most recent call last):
 28:   File "<stdin>", line 1, in <module>
 29: SystemError: The remote server returned an error: (500) Internal Server Error.
 30: 

And below is the C# code with the screenshot of the result:

  1: byte[] query = Encoding.UTF8.GetBytes("<?xml version=\"1.0\" encoding=\"utf-8\"?><soap12:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soapenc=\"http://www.w3.org/2003/05/soap-encoding\" xmlns:tns=\"http://www.witsml.org/wsdl/120\" xmlns:types=\"http://www.witsml.org/wsdl/120/encodedTypes\" xmlns:rpc=\"http://www.w3.org/2003/05/soap-rpc\" xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\"><soap12:Body soap12:encodingStyle=\"http://www.w3.org/2003/05/soap-encoding\"><q3:WMLS_GetVersion xmlns:q3=\"http://www.witsml.org/message/120\" /></soap12:Body></soap12:Envelope>");
  2: 
  3: HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://localhost:81/Petrolink.Powerstore.Webservice/wmls.asmx");
  4: // if SOAPAction header is required, add it here...
  5: req.Headers.Add("SOAPAction", "\"\"");
  6: 
  7: req.Credentials = new NetworkCredential("fred", "derf");
  8: req.ContentType = "application/soap+xml; charset=utf-8";
  9: req.Accept = "text/xml";
 10: req.Method = "POST";
 11: 
 12: Stream requestStream = req.GetRequestStream();
 13: requestStream.Write(query,0,query.Length);
 14: requestStream.Close();
 15: WebResponse response = req.GetResponse();
 16: 
 17: StreamReader sr = new StreamReader(response.GetResponseStream());
 18: 
 19: Console.WriteLine(sr.ReadToEnd());
