I am trying to simulate a sample web service payload similar to that which i will receive one the webservice is live. Can anyone help me simulate this?Criteria for my response will be:a bool pass or fail string - message and the object (in this case in the form of a list) heres the class I am to populate with sample data:
[Code]....
How can I use this class to put sample data in it? Lets say I want to put customers in the list 'ReturnObjects'?
I am creating new WCF service and i would like to do two way XML for communicating with third party vendors. My wcf service get the request from the outside program by means of URL and it should response accordingly.
Example - I have url which third party will call and put xml as a request, i have to get that xml, work accordingly and response back with either success or failure and appropriate xml. I need to make it completely automatic so anybody can call that url, it will validate that user and do the next step of request and response.
i am in the process of creating a restful service with WCF, the service is likely to be consumed by at least 500 people at any given time. What settings would i need to set in order to deal with this.
I wont to restrict my web service only for few domains.
I wont to have access to web service from using ajax and my page, and I don't want that anybody can create client to my WebService and view my web service methods.
I have to define a web method which will fetch XML documents from another web service based on the list of projects from the database. Now I need to send these XML documents in different SOAP envelopes. XML documents can be more than one.
if i have the web application with many pages like add order page, edit order page, and delete order page actually they also interact with the Sql Server 2008 and i also create web service page call Sales_Service.asmx. i know just i need to put something like query into Web Method in Sales_Service.asmx but i have a lot of queries, i don't know which query i should put into it and how the web page call the Sales_Services.asmx
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.
Maybe I am overthinking this a bit but I have a set of SSL enabled third party web services that I want to test. The url for the web service is essentially [URL]
Do I need to have a certificate setup on my test ASPX page to fully encrypt this connection or am I OK. with simply a simple ASPX page, create my objects from the WSDL and have at it?
I have a .net app developed in .net 4.0 version. And I implemented an asmx web service in this. Now I want to call one of the webservice method in another classis ASP application java script function.
Is it possible to run a web service as a particular user/service account in the same way a Windows service can?I have a service account used for connecting to the DB and want to run the webservice under this account as the users using the webservice won't have DB access.The way I see to do it is to include the Impersonate option in the Web.config file, but is there any better way to do this?
How to create an instance of web service without adding web service reference? How to identify the server address/name where the web service is hosted from C# code?
My WCF Client calls my WCF Service which then calls ASMX Web Service. The problem is i have configured my wcf client and wcf service to windows credentials type but when wcf service calls asmx service the user credentials (default windowsidentity) is not passed to asmx service.
In WCF Service i am able to get user identity by using : Thread.CurrentPrincipal.Identity.Name; WCF Service - i have disabled anonymous access and enabled windows authentication. ASMX Web Service - i have disabled anonymous access and enabled windows authentication. WCF Service Config [Code]....
i have created a normal web service and i want to host it outside IIS. one idea i got is to use window service as hosting environment. i have created a web service and hosted it window service and its window service is running now.would anybody please let me know that how can i call web service hosted in window service binded over soap.tcp. here is my sample code.
I am keep getting an error that "Service Error : wbsTest failed" where wbsTest is my webservice.
The error comes up frequently enough for the user - normally reproducible within a minute or so of working with an application.
A bit of background: An user is a remote user accessing application hosted on our servers over https. He is software firewalled and his connection isn't the fastest but it is responsive enough. When errors do not present themselves, page loads are fairly quick.
i want to know that should first name and last should be kept as sperate field or merged into single attribute. The Basic problem i am facing to keep first name and last name in seperate fields is that i cannot effectively use like query for searching a record by name

I am trying to call window's service from my web form but it is not working properly..kindly any one can tell me the procedure or rules that i have to follow to achive this scenario.
I'm having a doozy of a problem, and can't find a solution. I have a WFC Web Service installed to a pair of servers, and accessed through a load balancer. I am accessing the service from an ASP.NET client app, also via WCF. The Client is not load balanced.I'm getting an intermittant error:
(Inner Most Exception) System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond x.x.x.x:80(Middle Exception) System.Net.WebException: Unable to connect to the remote server(Outer Exception) System.ServiceModel.EndpointNotFoundException: Could not connect to http://<MYSite>/<MYApp>/<MYService>.svc.TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond x.x.x.x:80.
I can reproduce this error with about 20% reliability if I execute the exact same page request on the client from 2 browsers at the same time. When the problem occurs, the successful page request returns in about 5 seconds, and the failed page request returns in about 30 seconds.I'm guessing that there is some additional latency when the load balancer decides to switch my session to another server, and that is making some timeout setting on my client to be exceeded. I need to research this performance characteristic... any thoughtsbut its not my core question.My core question is... Exactly what setting can I tweak to increase the "period of time" the "connected party" is allows to "properly respond".This is the basicHttpBinding configuration I am using on both sides of the communication:
I've seen some indication that setting the receiveTimeout value on the server may help, but I set this to 1 second in a test environment, and was unable to reproduce the problem, leads me to believe its not worth a production environment change to verify this.
