Hi, I am using SP webservice. I think something is not right with my soap. Using Fiddler, I can see my soap request and response where I got HTTP 500 error when making a call to SP WS. Here is the Response: <?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><soap:Fault><faultcode>soap:Client.Dsp.Syntax</faultcode><faultstring>Request is empty.</faultstring></soap:Fault></soap:Body></soap:Envelope> And here is my soap request: <?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Header xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <dsp:versions xmlns:dsp="http://schemas.microsoft.com/sharepoint/dsp"> <dsp:version>1.0</dsp:version> </dsp:versions> <dsp:request xmlns:dsp="http://schemas.microsoft.com/sharepoint/dsp" service="DspSts" document="content" method="query"> </dsp

Getting error when referancing third pary .asmx in windows service as Service Referance



   I referenced a third party Web service (.asmx) WSDL file as service referance in Windows Service. When I execute from WCFTestClient.exe, I am getting response back. I am not able to create an instance of proxy in windows service. I could create in Web app. I am getting the following error.


"Could not find default endpoint element that references contract 'EDIService.notifyGasNomsEvent_PortType' 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."

.Net Frameword 4 SOAP Web Service



We want to upgrade from VS2005 to VS2010. Before we do that, I would like some clarity about some things.


Can we build typical SOAP webservices with the 4 Framework as I could with 2.0?


Would a WCF Service allow me to have both REST/SOAP services in one application?


Is Framework 4 ONLY for REST services and I need to stick to 3.5 for SOAP?


I downloaded the free Web Developer 2010, but I cannot seem to get anywhere trying to figure this out.


Thanks for any input.





Service Station: WSE 3.0, SOAP Transports, and More


It's that time again. Time to answer some of the questions I get on a regular basis. This month I'll look at service orientation and policy-based compatibility, SOAP's transport-neutral design, and Web Services Enhancements (WSE) 3.0.

Service Station: All About ASMX 2.0, WSE 3.0, and WCF


The release of the Microsoft® . NET Framework 2. 0 reshapes the Web services landscape in several interesting, and perhaps confusing, ways. So this month I'm going to field some of the most common questions related to ASP.

Service Station: Run ASMX Without IIS


When the Microsoft® . NET Framework first shipped, it introduced a breakthrough Web services framework known as ASMX. The motivation behind the ASMX design was to simplify the process of developing Web services as much as possible so that even if you're not an XML expert, you can get a Web service up and running.

Develop a Web Service: Up and Running with the SOAP Toolkit for Visual Studio


The new Simple Object Access Protocol (SOAP) Toolkit for Visual Studio 6.0 provides the infrastructure for developers to build, expose, and consume Web services. With a few exceptions that are outlined in the toolkit, the SOAP Toolkit complies with the SOAP version 1.1 specification. It includes the Remote Object Proxy Engine (ROPE), a Service Description and Code Generation Wizard, and code that provides ASP and ISAPI reference implementations of SOAP listeners. This article describes the tools and the object model of the SOAP Toolkit, and then demonstrates ASP and ISAPI implementations of a functional Web service using this toolkit.

ASMX ws: An unexpected error occurred on a receive; failing intermittently



we I have asmx web service, this seems to be working fine for 25 client machines but one site keeps failing. The client gets a small dataset and tries to send it across to server to process. The dataset saved in XML file only makes 450 - 550kB. The web service is contacted twice in a short time every half an hour. The other smaller dataset (50kB) goes across everytime without any troubles. This site is not trying to send the biggest dataset, other site are sending much bigger datasets without problem. The catch is this failing site keeps retrying for 20 times (10 hours) in average and then eventually goes across. I don't think the service webmethod is erroring out as that is all wrapped up in the try and catch and the exception is not getting thrown, also every other try for the exact same webmethod used by any other client site seems to be working fine.

System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

Custom tool error: Failed to generate code for the service reference 'CompanyService'. Please che


A little background because I feel I have an out of the ordinary architecture in place and don't know if this is contributing to the problem. 

We have an existing ASP.net application that is undergoing expansion.  The new functionality is all written in Silverlight 4.  As part of that expansion I gutted all the old Linq to SQL and put Entity Framework 4 into place.  To do this I created a standard .net Class Library and added my edmx files there.  Naturally, the business entities created by this cannot be used in Silverlight.  So I created a Silverlight Class Library and added all the business entities to that Silverlight Class Library as linked files.  I changed the name space to be the same.

So I have the following assembly / namespaces

Company.Project.Dal.csproj / Company.Project.Entities (.net 4 class library)

Company.Project.Entities.csproj / Company.Project.Entities (SL4 class library)

With this architecture I was able to share my business entities with my SL enabled web services, my asp.net projects, my silverlight projects.  Really it's a beautiful thing.

Once this was done I added "message" classes to Company.Project.Dal and again shared them with the other entites using linked files.  These messages are things like MyObjectRequest; they are class

"Your search cannot be completed because of a service error. Try ..."


i have a problem with search function where everytime i search any file/doc the error message "Your search cannot be completed because of a service error. Try your search again or contact your administrator for more information." occurred. I realized that there are items in central admin but it is "not available" in my site. I already follow several guides that had been provided in this forum but still the same. Even, i already create new SSP and configure the search scope, content source and also crawling. 

FYI, i used Microsoft Sharepoint 2007. 

Hope anyone could help me to solve this problem. Thanks.

RDL Rendering (500 Internal Server) Error at Sharepoint Integrated Reporting Service


I have a serious problem that cannot be solved by googling around the keywords below:
sharepoint, moss 2007, reporting service, ssrs 2008, rendering, internal server error, ....

The error is;

"An error occurred during client rendering. The remote server returned an error: (500) Internal Server Error. "

Everything is O.K.;

* When I render the report from the REPORTSERVER (http://localhost/ReportServer)
* When the reports are scheduled to be sent by the reporting service (planned via MOSS 2007) 

But if I open (render) the RDL file from the sharepoint REPORTS LIBRARY interface, all of the reports fail with that internal error message above. 

It is weird also that parametrized reports are displayed without errors although the parameters are queried from a sql dataset. But I got the error when rendering the report after I've chosen a parameter  and order "apply/report"...

Possible causes how I met that error may be;

After I have installed (then uninstalled) AJAX extensions
After I have re-configured IIS Web Service Extensions list items

Possible solution alternatives I've found;

I've found a solution on MSDN replying a similar issue with an ideal cause of the error but an evreka answer but no sol

VS2005 calling VS2010 asmx service returns empty string


Anyone have any experience with this?

We are using VS 2005 for the front end, and vs 2010 for the web services part (asmx), not wcf yet.


Web service works just like the vs2005 when run locally, no problems.


Connecting to it from a test app returns an empty string. Connecting to a 2005 app doesn't!

Anyone run into this before or have a suggestion? Surely vs 2005 can connect to web services from a later version?

Error Consuming Web Service - Unable to import binding xxx from namespace ...


In VS2008 / C# / ASP.NET 3.5, I wrote a test web service app. Here is an extract from the code:

namespace emed.MathWebService
    /// <summary>
    /// Sample Math Services For Learning Web Services Deployment
    /// </summary>

            return a + b;


I have published this to an IIS virtual directory named MathService, and when I try to launch it with the URL http://localhost/mathservice/MathService.asmx is works fine and displays all the operations (Add, Subtract etc) in the service.

I then created a test web application in VS2008 (named WebSvcTe
