WCF / ASMX :: FaultException Was Unhandled By User Code - "Server Was Unable To Process Request"
Mar 3, 2011
I have created a web service that interacts with my DAL. It has the usual kind of methods, create, retrieve, update and delete. I have published this web service to our live Windows Server and I can see the web serice URL. The web service works on a few method calls but does not work specifically for one object. I am getting the following error: Fault Exception was unhandled by user code. "Server was unable to process request. ---> Data is Null. This method or property cannot be called on Null values."
To summarise: Web service is live, I can see it in my browser. Some method calls work. One specific one does not. I have verified that the method works (it is just calling a SQL stored proc that does return data).
I'm getting an exception when trying to access an .asmx webservice within a MVC site. I've tried numerous things like updating the web reference within the console application and building another quick app to test, but can't get passed this issue. If I pull the URL out of the svc variable, I can browse to it directly.
Exception Details
System.Web.Services.Protocols.SoapException occurred Message=Server was unable to process request. ---> Value cannot be null. Parameter name: uriString Source=System.Web.Services Actor="" Lang="" Node="" Role=""
StackTrace:
at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at ClarityIntegration.SendTrackerDataToClarity() in [REDACTED].Reference.cs:line 78 at [REDACTED].Program.Main(String[] args) in [REDACTED].Program.cs:line 33 InnerException:
CONSOLE APP CODE
var svc = new TrackerClarityService.ClarityIntegration() { Url = url, Credentials = new System.Net.NetworkCredential("user", "pass", "domain") }; svc.SendTrackerDataToClarity(); svc.Dispose();
The exception was coming out of the Web Service itself. There were some global variables not being initialized directly through the .asmx call that were being initialized by the application itself.
Some simple checks on variables within the Web Service and setting what needs to be set have fixed up the issue.
I have a webservice, it has few webmethods. when i create a client proxy and invoke the methods to check its response, i am getting this error. Can someone tell me what things can i check to know the cause of this? The error is not saying much hence blocked on this.
I have made web service, when it is accessed by remote computer to send me the data using this web service then the following errors shows on the remote computer:-
"Server was unable to process request..A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"
When I am trying to invoke a method using a proxy class i get error
"System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.NullReferenceException: Object reference not set to an instance of an object. at ..."
I'm working on having two forms that communicate together. In order to do this, I am passing public value from the source page. Here's how I did it:
In the source page I have:
Public ReadOnly Property CurrentCity() As String Get Return txtboxfake.Text End Get End Property Then under page_load of the page I have: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load txtteam.Text = PreviousPage.CurrentCity txtboxdate.Text = Calendar1.SelectedDate End Sub
For some reason I keep getting an error that says "NullReference exception unhandled by user code" that points to txtteam.text = PreviousPage.CurrentCity.

I have a WCF based test harness client for a set of web services. The test client allows me to see raw requests and responses going to and from the services. A Message Inspector endpoint behavior is used to "pick off" the raw requests and response messages and save them for later display in the UI.
This works great, except for the use case where invalid credentials are passed. The server returns an HTTP 401 along with a SOAP fault containing details of what happened. This hurts me in a couple ways:
On the client this shows up as a MessageSecurityException not a FaultException, so I can't get the details from the fault. This exception appears to prevent the AfterReceiveReply event handler on my message inspector from firing, so I have no access to the raw response.
Is there any way I can handle this case so that the SOAP fault comes through as a FaultException and allow my message inspector to handle responses regardless of the HTTP status code that is returned?
