Web Services

A Web service is a method of communication between two electronic devices over a network. It is a software function provided at a network address over the Web with the service always on as in the concept of utility computing. A web service has an interface described in Web Services Description Language (WSDL). Other systems interact with the Web service in a manner prescribed by its description using SOAP (Simple Object Access Protocol) messages. There are two major classes of Web services: REST-compliant web services, and Arbitrary web services.

We have an ASP.NET application which uses multiple web services. It's an old project in Visual Studio 2010 that included the web services using dynamic discovery.

The project was initially published to a development machine running Windows Server 2003, but was changed to a 2008 R2 server some time ago. I'd now like to update the web references but trying to do that from within VS2010 results in the error -

There was an error downloading 'http://server.address/WS/WS.vsdisco'. The request failed with HTTP status 404: Not Found.

If I try to open the vsdisco from a browser on the server it returns -

HTTP Error 404.3 - Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

I've added the HttpHandler entry for vsdisco files to both the machine.config and web.config files on the server. The vsdisco file opens fine from a server running IIS6.

Is there a fundamental difference between IIS6 and IIS7.x that means this simply won't work, or can I just add a MIME record for vsdisco files? If so, does anyone know what the MIME type should be? I've tried 'text/xml' but that just returns a schema error.

I know this has been superseded by WCF services, but for the time being I'd rather not have to make a more major change to the code to implement that. The web services have been built using the .NET 2.0 framework.

Many thanks,…

Now that you have WordPress installed, understand the interface, and know how to install new parts, let’s take a look at our recommended plugins.

I have a C# WCF Service which is hosted in IIS 8.5 and has a number of web services. One of these web services is called MobileRegistration and when called from the Client works correctly (see below)

using (var svc = new DCRulesServiceRef1.TransactionClient())
{string returnval = svc.MobileRegistration(enterpriseId, userId, deviceId, qrcode);}

Open in new window

However I also need to be able to call the webservice MobileRegistration directly via a URL without having to go through the client. The URL I created is as follows

This fails with HTTP400 Webpage cannot be found.

http://xx.xx.xx.xxx/DCRules2Alias/Service.svc  does return the TransactonService Service page successfully.  So why can it not find my service. Is the format of the URL incorrect for a WCF web service ? Below is some of the relevant code and WSDL. Appreciate if someone can point out what I am doing wrong


Operation Contract for MobileRegistration web service
[WebGet(UriTemplate = "MobileRegistration?enterpriseId={enterpriseId}&userId={userId}&deviceId={devicerId}&qrcode={qrcode")]

        string MobileRegistration(string enterpriseId, string userId, string deviceId, string qrcode);

Open in new window

Web.config file

I want to create a web services (soap only) that allow php, aspx, and most common programming languages to consume my web services.
My native language is .net/c# with WCF. However, I am definitely okay to learn new stuffs if it is necessary.

All I need now is simple web services like "hello world" so I can get start it.
UseCase 1 :-  Http Method : Get , expected json is {"id":1, "effecitveDate" :"2017-08-13 08:10"} - working fine

UseCase 2 :- Http Method : Get, expecting a list of objects i.e. ["id":1, "effecitveDate" :"2017-08-13 08:10"} ,"id":2, "effecitveDate" :"2017-08-16 08:10"}

but I am getting  date like ["id":1, "effectiveDate": [
"id":2, "effectiveDate": [

How to solve this date issue.

I am part of a development for a SOAP web services client on WCF/.NET. After a session of sending request, team for server side left feedback "extend someAction from schema i am mentioning below", and mentioned an URL. In this context, what does it mean to extend from schema?
Hello, is there a command line tool that tests web services to see if they work?  Thanks!

I am using self written Java programmes at home that consume SOAP web services from my rc plane club. So far everything works good, But sometimes the SOAP web services that I use are not available due to maintnance or problems at the club's server. I want to monitor the availability of the SOAP services and persist the status. When I use the SOAP services the programme shall first check the availability from the monitor and if the status is 'available' perform the desired request or else queue the request until the service becomes available again.

Before I start to re-invent the wheel and write my own monitor I wanted to know if there are already tools that can accomplish this task, which can be easily embedded or used in Java before a request.

Best regards,
I have an XML file that when passed through SOAP UI returns a proper response as XML file. I need to create an application to pass the XML and recuperate the response. I tried searching but many say REST web service where they using only post/get.

Please send me some sample code and/or tutorials.
We are using Navision Web Services to publish the data so the third party application can consume, for our web services we need to pass username and password, I have done this several times using .NET but one of our client they are using Action Script and they are new to the web service.

Can anybody please help me with sample code for passing credentials, it is WSDL service.

websites provide android app fetching from rest api.
websites provide  rest api using c# with just one controller in project and sql server 2016 sending/receiving data for one table.
So these are not compact,efficient for complete project with multiple tables.
I am very curious to have modular code for all these concepts.

Dear sirs,
I am completing a web service whose role is to share data between a desktop application and a web one.
I can upload data (List<?>) using a HTTP POST request, download data using a HTTP GET request.
With a web service, once data is uploaded I can use the same routine to do further processing.
I had an intention to switch to FTP since the data to upload can be large, and send a HTTP POST request to trigger the processing of the data uploaded via FTP.

My concern is this one: if I stick to HTTP, what is the maximum size allowed in a HTTP request.

I need to create a web service in vs 2015. This web service will connect to active directory and get all different kinds of information.
I need to call the same web service from asp.net application, asp.net mvc and classic asp applications. What kind of service is preferred WCF or Ajax enabled WCF? Which is more clean and more secure??  This service is going to host in cloud environment.

Which wcf service is more commonly used in this kind of situation?

Where to begin.  I am not experienced with XML and SOAP so I may be using the wrong terminology.

I am writing an XML oriented Web Service consumer program (VB) using Visual Studio.  I used a text file WSDL, that I was given, to add a suitable web reference which includes one Method and about 10 classes which provide access to Request and Response XML elements.  The request and response both have "control" and "data" areas.

I was told that the web service requires credentials.  I was told that these credentials are to be placed in the Header of the SOAP envelope.  It appears that Microsoft, when creating the web reference, created a "client" oriented class which seems to be providing access to client credentials found in Microsoft's ServiceModel.Description class.

Anyway, when I try to run a simple test, I keep receiving an "OSB-386200 General Web Service Security error" when executing the Process method supplied to me by the web reference.  In WireShark, I see a "Client Hello" and a "Server Hello"...so basic communication is there.

1. Is the ServiceModel's ClientCredentials.Username (username and password) the right place to put the user and password?  Does this put the user / password values into the SOAP's header area?  
2. Is there a way to view the SOAP envelope message that is being sent to the web service from Visual Studio?  This would be very helpful to see if the credentials are being sent with the request data.  I am fairly comfortible with WireShark if…

I do not really know anything about REST web services but have some experience with SOAP web services.  A while back a developed a dynamic SOAP Connector that worked by exposing all the APIs in a SOAP web service along with the parameters for each.  This was very useful but I wanted to know if the same thing was possible for REST?  Again, I really don't know anything about REST web services and whether or not it would be possible to build something that would expose all the REST API's and Parameters.    A user of this application would then specify the API and fill in the parameters.  Can someone help me understand the difference between REST and SOAP and whether something like this would even be possible?
How to call WSDL from Stored Procedure in a SQL Server.
My server crashed and we had to start over.  We recovered the data and now have to add back our main website.

The first thing was to add web services back for an android app.  And were successfully added.  I see the application pool for it.
But I do not see a site for it.  It is running fine.

But then I add our main website and I place it under the default website in IIS (left side pane).
When I add the website (which runs .aspx pages), the site works fine and the .aspx pages work fine, however it interferes with the web services for android app causing those web services no longer to function.

I am looking for a list of possibilities and things to check so that both can run in harmony.
