WCF / ASMX :: Starting Integration With Web Services?
Mar 25, 2010
I'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.
I'm trying to use the First Data Global Gateway web service API. I was able to reverence the WSDL file in VS and get the classes to show up. I get the error "Object reference not set to an instance of an object." I can't figure out what I'm doing wrong.
We're doing a data integration project between a MS Sql Server database and a Microsoft CRM system (through its web services).
We're trying to build a "service" layer on top of the database. The design of our current solution is to use web services for CRUD, with xml being the format of data.
Views are created to consolidate related tables into one entity, and we query these views, using the "SELECT * FROM someview " + "For XML" to generated xml that will be returned from our web services.
For update we're trying to use the same approach - using SQL XML to map updates views, we have "instead of" triggers defined on top of these views, and in these "instead of" triggers we update the underlying tables.
The views/triggers are generated by tools so don't be too concerned with coding efficiency here...
what do you think if we use WCF data Provider to publish a enterprise data model (essentially DTOs) ? p.s., we don't have a BL layer for now, it's all in the stored procedures!!!
I'm currently building a .net web application that uses WCF web services to allow a Flex front end to access the database.
I'm in the process of setting up some unit/integration style testing on the web services and am trying to work out the best way to allow the tests to access and modify data in a separate test database.
Currently, the connection string in my unit test project points to my testing database, and the connection string in my web services project points to my development database. However, as I am using Linq it appears that when I call the web service methods from my test class, it uses the development database connection string. I have looked into creating mock objects or in-memory database but I believe the same issue would occur.
Is there a way to get this to work, or is my entire idea about what I want incorrect, in which case is there a better way to set this up?
I need a book or two to get a good understanding of web services, starting from very basics, and going upto WCF. I've been using c# for 2 years and have intermediate level of experience with the language.
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
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;
I have a wcf dataservice that talks to a silverlight client and a wcf service library that talks to a chat client.How can i get the two services to talk to each other?
ExchangeServiceBinding binding = new ExchangeServiceBinding(); binding.Credentials = new NetworkCredential(username, password); binding.Url = "http://servername/ews/exchange.asmx";
The above web services throws Unauthorized Access Error (Error : 401) for newly created users.I would like to know how to impersonate this user for accessing this exchange web services.
I have a simeple web service set up to call from JAVASCRIPT. That works. Can someone tell me how to access profiles from a web seervice. I get arofileCommon could nt be found......I have included the following in the service but it doesn't seem to solve the problem:
How to make web services secure in asp.net both the asmx and on WCF. Currently we have web services and now are in process of converting them to WCF in some modules in our application. Now as upgradation is in process we like to incorporate security on the web services as we intend to open some of them to all our clients via web (they contain both asmx and WCF as well).
I 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.
I am a .NET programmer trying to catch up on Java web services for an upcoming project in office. Can someone describe briefly what are the differences between .NET web services and Java web services?
