View 2 RepliesUsing ASP.NET 3.5 /C# / VS 2008.
I have written some web services that I want to make available to others by subscription. The subscribers need to use the service from a specific domain / IP address and also authenticate with a user Id and password.
What exactly should I distribute to the subscriber so they can use the services, while exposing the least about my code?How can authenticate a consumer of services without always passing an Id / password for each service?
I learned from internet that webservices can be invoked only by HTTP whereas WCF can be invoked by HTTP,TCP,et., can i know the difference between them
View 4 RepliesThese days I see that every other job posting requires LINQ and WCF. I have spent lot of time on LINQ, was fun to learn.
Now I want to move on to Web Services and WCF. After goggleing for some time, I am not sure either go for web services or WCF.
I've created Web Services in .Net 3.5 & Consumed those Web Services in a Client Web Application. Now i want to Host the WebService in IIS 5.1. I'm very new to .net, I'm using VS 2010, Wndows XP Service Pack 3, IIS 5.1;

View 3 RepliesI'm having my first experience with Web Services with .Net. I received from a client an integration manual to consume a web service they have.
In this manual I have the following information:
Request Interface: [URL]
Using SOAP request would return a XML Document with the response.
WSDL: [URL]
Request XML:
[Code]....
There's also XSD for the response XML.
Well, I'm having a little trouble trying to figure out how to consume this web service.
I found a topic here pointing to a MSDN article. There it says that I would have to add a Web Reference for this web service, but in my case this web service is external. Do I really have to add this reference to consume the web service? If yes how do I do that?
Next I have to create the XML Document that will be sent with the SOAP request. But here's a question. Searching on the internet I found mainly two types of request XML. I don't know wich one I should use.
The first one would be:
[Code]....
The second one is a XML file with soap:Body, soap:Header, soap:Envelope, etc.
Wich one should I create with my application in order to consume the web service? If it's the second one, how would look the XML for the data of the first XML?
And finally, how do I send the Soap request? As I said above, I found a MSDN article but it assumes I'm adding a web reference to the web service on my project and I belive that in my case I won't add this reference. So, how do I consume this web service?
I'm kind of lost here and really really soon I will have to estimate how long will take to develop the web service consume code.

View 1 RepliesI have a webservice, that when called, calls many other web services based on the information that was sent. I have always left the timeout as the default, or a better way to describe it, I have never changed anything.
How (and where) do I change the timeouts for each service individually. Since I have quite a few now, I want the original transaction to never take more than 30 seconds. That said. I want to go in and change the timeouts for the services I have to ping in that 30 seconds to be 5 to 10 seconds based on which one.

View 3 RepliesWhat is the use of XSD when providing web services to the client.?
How visual studio provieds XSD ?
What will be the situtation where we need to develop XSD mannually instead of use of Visualstudio.
Suppose I have created web services for Add method.
How the XSD will be.?
I'm working on an existing web application (web site project and some class library projects). In the web site project, the guys created many web services, that are called from the aspx pages (sometimes on client side).
I need to create a new web service, so I was suggested to put it "near" the existing web services. I'm gonna need to make an asynchronous call to my new web services.
So I created the service this way, but when I try calling a method asynchronisly, I have only the method in intellisense, I don't have the method for the asynchronous call, neither the Complete event. Why is that ?
On the other hand, I created a new project, with a web service application and a web site where I added the reference to the web service, and this way I have the asynchronous method and the complete event in intellisense.
Is there any way to check a web service's availability and get an alert whenever it is down?
I am supporting a very critical application and it went down few times because the webservice that it is supposed to be using was not accessible to it. So is there a way in which I could set up some monitoring and poll the web service periodically to check if it is available or not.
If calling the web service is the only way to check, I have a method in the web service which is supposed to return true.. How do I write code(windows app/web app/windows service/anything) so that it calls this method every 5 mins and sends me an email.
What would be the best way to setup the periodic polling, and how do I do it?
Why web services can't return an arraylist? Y it can return List<> only?
View 2 RepliesI created a simple test web service. It was tested and migrated to a website.
I then create a website to utilize the web service I have just created.
I created a web reference to the web service via URL. WDE2008 created a sub folder in the 'Web References' folder in my project folder. Everything looks OK at this point. I was able to code the call to the web service function with no compile errors.
I ran the web page locally via LOCALHOST and everything worked the way I expected.
Well, it works on the localhost so I decided to move it to the website where it should be...
I copied the ASPX page and codebehind to a sub folder of the website. I also created a folder called
App_WebReferences in the website root folder and copied the WSDL and DISCO files from my project there...
Now, here comes the problem... I got this error when I tried to pull up the web page! This is weird because it worked on my machine. I'm sure I'm missing something here.
Do I need to create any other folders on the website and hold WSDL and DISCO files because I'm sure the website needs some kind of mapping info to go get the web service!
I searched everywhere on the Internet trying to find any information about deploying the web page... but it is to my surprise, I could NOT find anything relevant to this. Everything I found was how to create web services and... run them on the localhost!!!
