SOAP - The remote server returned an error: (500)

19-Sep-06 1:07

There are two things that you may need to check when you host an Active control on your web page.
+ Make sure that the control is properly installed and registered on the client machine.
+ Make sure that the permission is granted to your application so that the client side script can create a new instance of the control.

Need help using PostBackURL

18-Sep-06 18:35

Hi All

a) I am getting error "The remote server returned an error: (500) Internal Server Error." whenever i tried to call web service.

b) I need to pass my web method name as runtime paramter. As web service can contain multiple web methods.....I am trying to pass as SOAPACTION but i am not sure syntax or infact is it correct way or not....

FYR i am sharing source code as below
Client Code:
'Create a new HttpWebRequest to the mentioned URL.
'hard code for time being
httpRequest = WebRequest.Create("http://localhost/XYZWS/XYZCustomerService/XYZCustomerService.asmx")
' Set Request information (Header, ContentLength, ContentType, etc)
'hard code for time being. Passing sxml here.
Dim bodyData As Byte() = Encoding.UTF8.GetBytes(sXML)
httpRequest.ContentLength = bodyData.Length
httpRequest.ContentType = "text/xml; charset=utf-8"
'hard code for time being in future it will be thru parameter
httpRequest.Headers.Add("SOAPAction", "SaveCustomerService")
httpRequest.Method = "POST"
' Set 'Preauthenticate' property to true. Credentials will be sent with 'the request.
httpRequest.PreAuthenticate = True

' Create a New 'NetworkCredential' object.
Dim networkCredentials As NetworkCredential = New NetworkCredential("A", "b")

' Associate the 'NetworkCredential' object with the 'HttpWebRequest' object.
httpRequest.Credentials = networkCredentials

' Create a new RequestStream to POST info (Synchronous call)
requestStream = httpRequest.GetRequestStream()
requestWriter = New StreamWriter(requestStream)

'Write Soap message into RequestStream
requestWriter.Write(sXML)

' Cleanup
requestWriter.Close()
requestStream.Close()

' Create a new HttpWebResponse (Synchronous call)
'HttpWebResponse response = httpRequest . GetResponse ( ) as HttpWebResponse

'Dim httpResponse As System.net.HttpWebResponse
'httpResponse = httpRequest.GetResponse()

Dim httpResponse As HttpWebResponse
httpResponse = CType(httpRequest.GetResponse(), HttpWebResponse)

' Extract normal SOAP response.
responseStream = httpResponse.GetResponseStream()
responseReader = New StreamReader(responseStream)

'Fetch the XML.
Dim httpResult As String = responseReader.ReadToEnd()

' Cleanup
responseReader.Close()
responseStream.Close()

' Return XML.
'Return httpResult

Catch myerr As WebException
' Populate the table with the exception details.
ErrorTable.Rows.Add(BuildNewRow("Source", myerr.Source))
ErrorTable.Rows.Add(BuildNewRow("Error Message", myerr.Message))
ErrorTable.Rows.Add(BuildNewRow("Status", myerr.Status))
'ErrorTable.Rows.Add(BuildNewRow("Response", myerr.Response))
ErrorTable.Rows.Add(BuildNewRow("Detail", myerr.StackTrace))
Return
Catch myerr As SoapException
' Populate the table with the exception details.
ErrorTable.Rows.Add(BuildNewRow("Fault Code Namespace", myerr.Code.Namespace))
ErrorTable.Rows.Add(BuildNewRow("Fault Code Name", myerr.Code.Name))
ErrorTable.Rows.Add(BuildNewRow("SOAP Actor that threw Exception", myerr.Actor))
ErrorTable.Rows.Add(BuildNewRow("Error Message", myerr.Message))
ErrorTable.Rows.Add(BuildNewRow("Detail", HttpUtility.HtmlEncode(myerr.Detail.OuterXml)))
Return
End Try

</code>

Now here is web service code and GetXMlValue is custom function to read xml node value

<WebMethod(MessageName:="SaveCustomerService")> _
Public Function SaveCustomerService(ByVal CustomerService As String) As String
Try
Dim sUserName, sEmail, sCategory, sSubject, sMessage As String
sUserName = GetXmlValue(CustomerService, "username")
sEmail = GetXmlValue(CustomerService, "email")
sCategory = GetXmlValue(CustomerService, "category")
sSubject = GetXmlValue(CustomerService, "subject")
sMessage = GetXmlValue(CustomerService, "message")
SaveCustomerService(sUserName, sEmail, sCategory, sSubject, sMessage)
Catch ex As Exception
Dim a As New ThrowSoapException
a.myThrow()
End Try

FYI
For probelm one i added below line of code in web.config of web service also

<webServices>
<protocols>
<add name="HttpPost" />
</protocols>
</webServices>

Thanks in advance....

hi friends,
I'm trying an example on PostBackURL.My application has two pages,page1.aspx & page2.aspx. On page1,I've a textbox & a calendar with 2 button controls.I'm trying to display the selected contents on Page1 into a label on Page2.Here's what my code on Page1.aspx looks like

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Label1.Text = "Hello " & TextBox1.Text & "
" & _
"Date Selected: " & Calendar1.SelectedDate.ToShortDateString()
End Sub

<asp:button id="Button1" runat="server" text="Submit Page to itself" onclick="Button1_Click">

<asp:button id="Button2" runat="server" text="Submit Page to Page2.aspx" postbackurl="~/Page2.aspx">

On Page2.aspx, I've included a virtual path to reference page1 &
Code on page2.aspx is:
Protected Sub PageLoad(ByVal sender As Object, ByVal e As System.EventArgs)
lblDisplay.Text = "Hello" & PreviousPage.pp_TextBox1.Text & "
" & _
"Date Selected: " & _
PreviousPage.pp_Calendar1.SelectedDate.ToShortDateString()
End Sub

I'm not getting any errors & neither am i getting any display on Page2.aspx. can anyone please help me find the solution ?

Thanks a lot in advance..

the easiest way is using response.redirect option

On page 1

string text1 = TextBox1.Text;
string text2 = Calendar1.SelectedDate.ToShortDateString();

response.redirect("page2.aspx?message1=" +text1+",message2=" +text2 ,true);

On page 2

string ms1 = Request.QueryString["message1"];
string ms2 = Request.QueryString["message2"];

Its on C#

hi Britney,
I tried this piece of code but still I'm not able to display the contents of textbox & the selected calendar date onto a label on page2.I've written the response.redirect code in a Button2_Click Sub. The control is transferred from page1 to page2 and the page2 url will carry the contents of strings message1 & message2, but they are not being displayed onto the label.Can you please tell me where I'm going wrong ???

thanks a lot for your help.

How do you define properties pp_TextBox1 and pp_Calendar1? Can you see the TextBox and Calender controls with the selected values in the PreviousPage when you step through your code? Another option to get reference to the controls of the Page1 is to use the FindControl method.

Meena T Shivaram19-Sep-06 3:56

19-Sep-06 3:56

pp_TextBox1 and pp_Calendar1 are the property procedures that I've written to retireve the values from TextBox & selected date on Calendar.I've two buttons on Page1. When I click on Button1, the contents of TextBox & selected Calendar date are displayed onto the same page on a label.I'm able to get this .When I click on Button2, I want to transfer the contents of TextBox and Calendar control to a label on Page2. When I click the Button2, the Page2.aspx form is loaded but I dont see any display on the label...
I'm working this example from Professional ASP.Net 2.0 book by wrox publications.They have given an example using FindControl method but I didn't get any output on Page2.aspx even then..So, please tell me where I'm going wrong ???

Thanks in advance..

Because the textbox is inside of a container control you need to reference it with the name of that control also. If you look at the rendered output of your page you should see the textbox with an ID something like UserControl1_MyTextbox.

SOAP Message

Amit Kumar G18-Sep-06 8:06

18-Sep-06 8:06

My apologies for very very basic question. I am going through with SOAP messaging and found

“Nor SOAP is tied to any particular operating system or programming language so theoretically the clients and servers in these dialogues can be running on any platform and written in any language as long as they can formulate and understand SOAP messages”

How internally it make difference? I mean SOAP is nothing except massaged XML with SOAP headers, envelope and body. I really interesting to find difference between SOAP message and plain XML message without SOAP..

The difference is the standard defines what each tag means (Envelope, Header, etc) and what it should contain. Plain XML could do the same but it would be up to each sender and receiver to agree upon the format and meaning.

Add a reference to the web service in your project

Then you simply make calls to it: MyWebService.SaveCustomer(...)

Thanks for your reply. But because of certain design pattern we are developing adaptors and we need to create request on fly. Web service url, method name all will be avaibale on runtime.....

Please suggest.

SOAP Message uses specific namespace which make it different. If you create an xml document with same format like enevelope and message without namespace, it will be considered as an xml doc rather than SOAP.
