C# - SoapException Server Was Unable To Process Request On ASMX Webservice In MVC Site?

Mar 9, 2011

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.

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).

Unable to start debugging on the web server.

WCF / ASMX :: Accessing Response Of HttpWebRequest, Even When Request Returns 500 Internal Server Error

Oct 22, 2010

Hoping someone can point me to a solution, haven't been able to find one yet.

I'm using the standard way for send HttpWebRequest

[Code]....

As you can see from Fiddler/SOAPUI it does return the SOAP fault, however using HttpWebRequest i can't capture the response.

Returning 500 triggers my exception handling and Capturing the WebException doesn't expose the response.

Does anyone know how to capture this response xml in the case of 500 Internal Server Errors.

WCF / ASMX :: IIS Memory Increasing For Each Client Request In Asmx Web Service?

Nov 8, 2010

A customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.

We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.

We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.

C# - How To Optimize Spawning A New Process For Each Request

Mar 9, 2011

I have an asp.net mvc application that spawns a Process as follows:

Process p = new Process();
p.EnableRaisingEvents = true;
p.Exited += new EventHandler(p_Exited);
p.StartInfo.Arguments = "-interaction=nonstopmode " + inputpath;
p.StartInfo.WorkingDirectory = dir;
p.StartInfo.UseShellExecute = false;
p.StartInfo.FileName = "pdflatex.exe";
p.StartInfo.LoadUserProfile = true;
p.Start();
p.WaitForExit();


Before going further, I need to know whether, e.g., pdflatex.exe is a managed code or a native code? Edit 1 I need to consider this because: (Hopely I am not wrong...) Each Asp.net application runs in an separate/isolated AppDomain as opposed to a separate/isolated process. A native executable cannot live in an AppDomain.to be continued.. Shortly speaking, I hope my site does not spawn a new process for each request. Because a process is more expensive than an application domain. Edit 2 My asp.net mvc application allows users to submit LaTeX input commands such as $ax^2+bx+c=0$ to be converted to a pdf file rendering an quadratic equation. Behind the scene, this web app will spawn a process executing pdflatex.exe. The job of pdflatex.exe is converting the LaTeX input commands to pdf document.

IIS 7 To Process The Request Queue In Parallel?

Apr 20, 2010

Currently we are developing an ASMX, ASP 2.0, IIS 7 web service that does some calculations (and return a dynamically generated document) and will take approx. 60 seconds to run.Since whe have a big machine with multiple cores and lots of RAM, I expected that IIS tries its best to route the requests that arrive in its requests queue to all available threads of the app pool's thread pool.But we experience quiet the opposite:When we issue requests to the ASMX web service URL from multiple different clients, the IIS seems to serially process these requests. I.e. request 1 arrives, is being processed, then request 2 is being processed, then request 3, etc
