I am trying to learn webservices in .NET mvc4. I tried creating a new Internet application and adding a Web service (asmx) to the project.
By default, the VS adds a "HelloWorld" Webservice. When I try to run it in the browser, I do get the list of operations, service description(WSDL) and the details of the HellowWorld operation. However, when I try invoking the webservice, it gives the following error :
Server Error in '/' Application.
The resource cannot be found.
Description: 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. Please review the following URL and make
sure that it is spelled correctly.
I might be missing some basic step/setting I guess. Could some body help please. Thanks.
I got the answer from one of my colleagues :) .
When we invoke the service, the MVC tries to resolve the path as specified in RegisterRoutes.
Hence it tries to find a controller with that name and a method with the name same as that of the operation inside that controller. The resolution, ignore the paths with .asmx extension. You can do that by adding the following line in RouteConfig.cs :
routes.IgnoreRoute("{*x}", new { x = #".*\.asmx(/.*)?" });
and it worked. Thanks.

We migrated our outdated ARR to an High Availability ARR solution. The problem we are facing now is on a WCF web service.
When I navigate to www.company.com/webservice/service1.svc I get the error:
Server Error in '/' Application. The resource cannot be found.
Description: 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. Please review the following URL and make
sure that it is spelled correctly.
If I navigate to www.company.com/webservice/ I can see all the files including service1.svc.
Any pointers to where to look? I cannot figure it out.
Appreciate your time
After building and deploying, checked the solution management from Central administration and it's up, a simple web service method that only created a Document Library list with a few columns when trying to retrieve the wsdl or even just by calling the WS fromt the adress since its a void method I recieve some error:
The file you are attempting to save or retrieve has been blocked from this Web site by the server administrators.<nativehr>0x800401e6</nativehr><nativestack></nativestack>
The very same method runs fine when called from another web service project that is already deployed so there's nothing wrong with the code. I'm most probably doing something wrong but can't figure.
The system is running on a win server 2008 with sharepoint 2010, framework 3.5 and "ANY" cpu mode.
thank you!
[edit]
Managed to get rid of the previous error by removing asmx extention from the blocked file list in central administration now instead I'm recieving a 404 error:
The resource cannot be found.
Description: 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. Please review the following URL and make sure that it is spelled correctly.
Requested URL: /_layouts1/my2claims/tt_claims.asmx
it must run under the same application pool as SharePoint
I have an application that calls a Https web service (as it seems created with java, not sure though). I get an error as response:
"Error on verifying message against security policy Error code:1000"
Now I don't exactly understand the error code and currently cannot find any responsible to answer me correctly. I don't ask for the error ofcourse cause this could be something about certificates, security from server etc.
Though I would like to catch the request client call I make, and see the whole envelope message to compare with a couple of samples I have so I might catch something.
How can I do this....I remember there is a tool that u can do such things when debugging a WCF service call, can this tool be used in this situation? Can someone rember me the name of the tool :)
I created the client using Add Service Reference, from VS 2010 and it created some custom bindings. On these bindings it created this a tag with an attribute decompressionEnabled="true" but I deleted because VS was complaining attribute is not allowed!!!
The documentation I have for these services says about authentication credential inside the message transport object that serialized in the request (requestObject) but refers to another couple of password and username properties I cannot seem to find them. Tried to add the in client.ClientCredentials.UserName.UserName and Password properties, but I get a read only error there (strange not always).
They also mention in the specifications about Connect with SOAP Security Extensions (WS-Security) which I don't understand if me, the client, has to do something from it's side, aren't these supposed to extract in the config file when generated?
Any hints and tips are welcome.
Thank you.
I have a web service that is running on a test instance in IIS. Unfortunately, certain requests to it cause it to throw basic errors like "Object not set to an instance of an object".
The people who use the webservice then send me the full HTTP request (including headers) that caused the error, which I now need to throw at the instance running in my development environment to bug fix.
Any suggestions on how to do this? (Putty would work but you cant copy and paste into Putty when its connected and that makes for laborious debugging!)
http://www.soapui.org/
SOAP UI is a nice soft for this kind of things, you can add your reference, and then copy/paste your friends request !
To add your reference :
Launch SoapUI
Right Click on "Projects"
New SoapUI Project
Fill the "Initial WSDL" textbox with your local wsdl url (ie "http://localhost:1234webservice.asmx?wsdl" (don't forget ?wsdl))
Click "OK"
To execute your request
Expand your newly created project
Expand the port you whish to use (the main difference is the wsdm version 1.1 or 1.2)
Right click on your Method
"New request"
On the Request windows copy /paste that you received
Click on the green triangle on the top right corner of this window.
Use soap UI. http://www.soapui.org/
Somebody posted Fiddler http://www.fiddler2.com/fiddler2/ on this answer earlier and then deleted it - I gave it a try and it works fantastically. (thanks)
I'm trying to built a SharePoint Web Part that has as part of it a service reference to Another SharePoint server that I need to call from within vb code. However when I try to call the remote web service for the first time, I get the following in the log:
Could not find default endpoint element that references contract 'ListReference.ListsSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element. at System.ServiceModel.Description.ConfigLoader.LoadChannelBehaviors(ServiceEndpoint serviceEndpoint, String configurationName)
at System.ServiceModel.ChannelFactory.ApplyConfiguration(String configurationName)
at System.ServiceModel.ChannelFactory.InitializeEndpoint(String configurationName, EndpointAddress address)
at System.ServiceModel.ChannelFactory1..ctor(String endpointConfigurationName, EndpointAddress remoteAddress)
at System.ServiceModel.EndpointTrait1.CreateSimplexFactory()
at System.ServiceModel.ClientBase1.CreateChannelFactoryRef(EndpointTrait1 endpointTrait)
at System.ServiceModel.ClientBase1.InitializeChannelFactoryRef()
at System.ServiceModel.ClientBase1..ctor()
at VSeWSS.ChangeRequestWorkflow.ChangeRequest.SubmitForm(Object sender, EventArgs e)
What is the proper way to deploy a Web Part with a Service Reference, could I be doing something wrong? Thanks!
You need to add the endpoint configuration into the web.config of the SharePoint site that is consuming the webservice.
I found this question that solved my problem.
Basically, I just needed to create a BasicHttpBinding object and populate its properties with the ones the SVC generator made in my app.config.
WCF Configuration without a config file
Actually I solved my problem. My application has many projects, and the config file was in the project calling the WebService, but it seems it has to be in the starting project...
Hm, if I'm understanding what you're asking correctly, I'm doing that. I just added the webservice from one of the correct endpoints to the project in VS, then before I call it in my actual code, I get the URL I want to connect to with this call from the hierarchical object store from Codeplex, then set the Url property. So:
MyService srv = new MyService();
srv.Url = SPContext.Current.Web.Properties["serviceurl"];
Its working like that fine.
hth.
