Internal 500 Server Error Soap Message

[kahlua001]

Hi,

I have a webservice that has one method and takes in a string as a paramter, pretty simple. On my client app, I build the soap envelop and post it using HttpWebRequest but I'm getting a Internal Server 500 Error, any clue to what i'm doing wrong? WSDL is not an option for me here.

 

Dim strSoap As String

           strSoap = "<?xml version=""1.0"" encoding=""utf-8""?>" & vbCrLf & _
           "<soap:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">" & vbCrLf & _
           "  <soap:Body>" & vbCrLf & _
           "    <submitCarriersStatus xmlns=""http://beta.webservices.netcour.com/fedex"">" & vbCrLf & _
           "      <strXML>" & str214 & "</strXML>" & vbCrLf & _
           "    </submitCarriersStatus>" & vbCrLf & _
           "  </soap:Body>" & vbCrLf & _
           "</soap:Envelope>"

           Dim req As HttpWebRequest = WebRequest.Create("http://tempuri/fedex/FedExStatusTest.asmx")
           req.Headers.Add("SOAPAction", "http://tempuri/fedex/submitCarriersStatus")

           req.Method = "POST"
           req.Accept = "text/xml"
           req.ContentLength = strSoap.Length
           req.ContentType = "text/xml"
           Dim sw As New StreamWriter(req.GetRequestStream)
           sw.Write(strSoap)
           sw.Close()

           Dim resp As HttpWebResponse = req.GetResponse
           Dim strResp As String = ""
           Dim sr As New StreamReader(resp.GetResponseStream)
           strResp = sr.ReadToEnd
           sr.Close()

It sounds like you may have friendly http errors enabled. Try going to (Internet Explorer)

 

Tools -> Options -> Advanced -> Disable Friendly HTTP errors

 

that should give more detailed information than just internal server error.

You mean in IE? I am using vb.net to send a request, the error that gets returned is a 500 server error, not using IE

[Nate Bross]

Sorry. I misunderstood.

Can you step through the web service code in a debugger? If so see where it fails as a 500 error is a bit vague as to the problem itself.

Also, just out of curiosity more than anything, is there a reason why WSDL isn't an option?

What I'm doing is trying to use a wsdl from a web service on a Tibco server. The company who owns that Tibco server sent me a wsdl which .Net does not like, all sorts of name space errors and datatype missing errors which I tried to adapt to .Net friendly stuff, but in the end, wasted too much time and not getting it just right. So we dumped the idea and I went straight to constructing the soap message and sending them the data via a HttpWebRequest. On a side note, does anybody know of any differences between Java world wsdl and Microsoft world wsdl? You would think this should be universal...
