AJAX :: Http 417 Error While Calling A Web Service?
Apr 20, 2010
i got a this exception when i calling my web service in producction server.i already test the web service in server side and this don't have problemasbut when i calling the web service in the development site this throw a
(spanish)"Error de la solicitud con el código de estado HTTP 417: Expectation failed." or
(english)"The request failed with status code HTTP 417: Expectation failed."
When I am trying to call a service hosted in Java through .net I am encountering the below error
"WSE839: An HTTP response was received that used the following content type: text/xml; charset=utf-8. The following content type was expected: multipart/related; type=application/xop+xml."
If I call my web service directly it works, however, when I try to call it from another controller on the same project I get a 401 exception. Below is the code I use to call the WS, and it is being run in VS not IIS.
We have had some problems with using a unmanaged DLL file written in Delphi. (Unable to load dll - not found...)The following code solved the problem on my local machine:
[Code]....
1) The elusive DLL is copied to the ASP.NET temporary files folder2) To check this we get a list of files from that folder.3) The needed function is called with DLL-import.1 & 2 works perfectly - both run directly from Visual Studio 2010 and when uploaded to a webhotel3 works perfectly local, but causes the remote host to think a little and then return a HTTP 503 Service Unaviable error for the next few minutes...
I am calling a remote service and authenticating using a certificate. When testing with a Console App, everything works fine. When calling from an ASP.NET Website (.NET 4.0, IIS7) I receive a response code of 401 -- Unauthorized.I am adding the certificate using code such as:
var client = new TheGeneratedProxy(); client.ClientCertificates.Add(new X509Certificate("D:cert.pfx", "myPassword"));
(NOTE: I have also loaded the .pfx into the local Certificate Store using IE. The certificate is loaded into my "Personal" store -- so I suspect this to be the problem, since the Website will be running under a different account.)
I am trying to call a service from a silverlight application, but I am getting the following error.
Uncaught Error: Unhandled Error in Silverlight Application An exception occurred during the operation, making the result invalid. Check InnerException for exception details.
This works fine locally. I don't know if it make any sense, but locally if I add the url of the webservice on a browser, I am getting the details page of the service. In the other hand, on production server, it prompts me to download it.
public MainPage() { InitializeComponent(); Loaded += new System.Windows.RoutedEventHandler(MainPage_Loaded); }
I created an AutocompleteExtender web service. I am getting a Object reference not set error in the peice of the code where I am referring to System.Web.HttpContext.Current.Session. Does anyone know why this is. And I am checking to see if it is != null before I reference it. But it crashes. Is there another way to pass another parameter to the web service?
I have wcf web service, I works fine on my local machine,but when I move it to live then it throws following error
System.Security.SecurityException: Request for the permission of type 'System.Configuration.ConfigurationPermission, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' failed.
I am new to WCF, I was using web service asmx before. I have trouble on making my wcf JSON ajax service work through http like asmx.Could you help me see what wrong in my code?My WCF services are defined in my website application folder. My aim is to call this service in my aspx page java-script code and return complex object back as JSON to my javascript. I have no problem on doing this through classic asmx web service.
When I try to test it through my browser by type this in the URL , URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc/GetAll. it return "Method not allowed."
But if I type just this URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc, it return this:
WCFCompanyService Service
You have created a service.To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax:
This will generate a configuration file and a code file that contains the client class. Add the two files to your client application and use the generated client class to call the Service. For example:
C#
class Test { static void Main() { HelloClient client = new HelloClient();
we have a situation where we need to host two certificates on the same server and because we can't have two different certificates on the same server running off the same port we have assigned one certificate run through another port, which is 4443.
So the URL to our web app is now....
[URL]
If I punch this into a web browser I can access it fine, however, if I create a web reference using this URL in Visual Studio (2005) it can create the web reference fine and it builds ok. But whenever I call a web method on this service instance I get a HTTP 404 page not found Exception.
Is there any properties I need to set on the web service object to get this to work? I'm confused as to why it's not working.
I am currently writing a C# web service which has several methods, one of which has to receive HTTP POST requests. The first thing i have done is alter the web.config file in the web service project as below.
[code]....
But when i run this i get "The remote server returned an error: (500) Internal Server Error". If i remove the parameter, by removing the stringbuilder and byte code, as well as having no parameter in the web service, it works. So it is obviously a problem with the parameters. I actually want to send more data, and was using a string[] parameter in the web service, but this also failed.
I have an AJAX auto complete extender that calls a web service to generate a string[] for a textbox. Works great, The issue I am having is that I set the OnClientItemSelected property of the auto complete extender to call a JavaScript function that will intern call another web service to get the remaining data I need based on the item that was selected. (I need this because the auto complete web service only allows for key/value pairs and I need to return 10 columns of data) I cannot get the JS function to call the web service. I keep getting "(Namespace) is undefined" as a JS error. I tried to impliment Microsoft's example located at: [URL] but even if I copy there code line for line in a new project, I still encounter the same error.
Samples.AspNet.WebService.Add(a, b,SucceededCallback); //'Samples' is undefined - runtime If I remove the namespace so that it reads: Add(a, b,SucceededCallback); //Endless loop until you get stack overflow error Has anyone got MS C# example to work? I saw a lot of people had this line missing in the web service, but I already had it. [System.Web.Script.Services.ScriptService]
I am new to Ajax and i wanted to use the CascadingDropDown to get rid of the postbacks. But somethings wrong and when i debug i am not running any code from the Web Service for some strange reason.
I have one asp.net application, in which i am using "Calling WCF Service Operations in AJAX" method. I finished my work without the service hosting in IIS. I got the correct solution. But now, i have another requirement in which i am using the WCF service which is hosted on local host iis. But in clicking the button i got one javascript error like object expected. I don't know why this happened? My code is shown below.

I am connecting to remote server for web service using ASP.NET 3.5 web site. something like, [URL]. Remote server is providing digest authentication to access the web service. I dont have access to modify authentication on the remote server but I have an windows account on that server. If I try to Access service WSDL through programming I get the following error:
The request failed with HTTP status 401: Unauthorized. Same web service if I try to access through browser, [URL], it asks for user name and password. Entered windows account user name and password, still getting error: You are not authorized to view this page, HTTP Error 401.1 - Unauthorized. How to pass the digest authentication credentials to the web service through visual studio or any other programmatic method?
I am trying to call an asmx service using the jQuery ajax call-
[Code]....
I have double checked the url of the service and spelling/case of the name of the method as well as the parameters in the dataStr.
I still get the error-<b> Description: </b>HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. review the following URL and make sure that it is spelled correctly.
I have one ajax call web service, and want to add some http headers using javascript, can we do that use setrequestheader in ms ajax?This is my javascript
3) Finally adding the reference of service contract project in a Hosting project (Console Application) with complete configurations.
I am adding one more windows app project as a client.When i am trying to add the service reference using the address "http://localhost:8000/Tasks", VS 2008 displays the below error.
There was an error downloading 'http://localhost:8000/Tasks'.
Unable to connect to the remote server
No connection could be made because the target machine actively refused it 127.0.0.1:8000
Metadata contains a reference that cannot be resolved: 'http://localhost:8000/Tasks'.
Could not connect to http://localhost:8000/Tasks. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:8000.
Unable to connect to the remote server
No connection could be made because the target machine actively refused it 127.0.0.1:8000
If the service is defined in the current solution, try building the solution and adding the service reference again.
When I was reading the blog Using jQuery to Consume ASP.NET JSON Web Services
I have seen this argument:
"By using jQuery to call the web service directly, we've eliminated over 100 KB of JavaScript and three extra HTTP requests. "
Why does the ASP.NET AJAX call to a .NET Web-Service needs 3 extra HTTP requests? What are those requests? (I wonder how jQuery manages the call with lesser HTTP requests in this case).
web service method(getMainHeads) with parameter is not calling with auto complete text box extender(same method with out parameter is calling fine). My Service is
[System.Web.Script.Services. ScriptService] public class InvService : System.Web.Services.WebService { ItemMainHeadMsts objItemMainHeadMsts; DatabaseHelper objDataHelper; [WebMethod] public string[] GetMainHeads(string value) { List<string> oList = new List<string >(); objItemMainHeadMsts = new ItemMainHeadMsts (); objDataHelper = new DatabaseHelper (); objItemMainHeadMsts = ItemMainHeadMstBase.SelectByFieldAuto("IMHDesc" , value); foreach (ItemMainHeadMst mainHead in objItemMainHeadMsts) { oList.Add(mainHead.IMHDesc); } return oList.ToArray();..........................
In IIS I have a virtual directory with only windows authentication enabled. From Javascript I call into a ASMX webservice. From the ASMX webservice I make a call to the SharePoint Search.asmx Webservice. whatever I try I keep getting the followin gerror message:
"The request failed with HTTP status 401: Unauthorized"
I use the following code to call the SharePoint webservice
[Code]....
My web.config settings are:
[Code]....
The Sharepoint farm is configured to use NTLM authentication.
Strangely everything works when I am testing in Visual Studio using the builtin webservice, but when I deply to my local IIS or Test Server it breaks.
I'm using a custom AJAX based validation control to check user name availability from database. It's working alright in my development machine but in production server we are using Windows Authentication to authenticate by domain.The control is inherited from base validator and checks for user name availability from database perfectly but on form submission at Page.IsValid check it gives the following error.
remote server returned an error 401 unauthorized
Both the form and webmethod are in the same page/file. I even tried creating webmethod in a separate standalone webservice but error still there.
when i am adding service reference the Following erro shows Up..where as the same works on the Other machine. The url when tested in Internet explorer works but only while adding shows the error. The request failed with HTTP status 403: Forbidden. The HTTP request was forbidden with client authentication scheme 'Anonymous'.
