Hey Folks. I was wondering if anything special is required to add a .NET web services to the "Services" tab in NetBeans to allow my java app to consume a .NET web service.
I go and add my WSDL (simple method, 1 operation, takes a string), and I continuously get a NullReferenceError as below:
java.lang.NullPointerException
at org.netbeans.modules.websvc.saas.model.wsdl.impl.WsdlModel.getServices(WsdlModel.java:65)
at org.netbeans.modules.websvc.saas.wsdl.websvcmgr.WebServiceManager.addWebService(WebServiceManager.java:142)
at org.netbeans.modules.websvc.saas.wsdl.websvcmgr.WsdlDataManagerImpl$1.run(WsdlDataManagerImpl.java:79)
at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:1418)
[catch] at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:1957)
Is this something common?
I'm using Netbeans 6.9.1 and yes, the webservice is a stub that takes a string and displays a static message right now.
OK. Installing (Tools->Plugins) the SOAP web services plugin fixed my problem. Duh!

The project I'm holding is asp.net website with static content [aspx files]
SOAP WSDL to the web services is provided and it's built with java and I have added a service to the project using "Add Service Reference".
I am looking for a way to consume that API with the website so as I could not understand how to call and integrate the data out of service and locate it into HTML[.aspx] page.
I have worked mostly with MVC projects but in this case I have not found any clue on how to do that.
After looking for many resources, Here is a conclusion how i solved my problem in case anyone needed that later in WebForms and C#.
1.Add Service Reference to your project using the WSDL link
provided
now you have classes and functions identified to your project.
Import the namespace to your class or your webform page using corresponding syntax and after that you can instantiate object out of classes and use functions
using namespace.webserviceName; with class
<%# Import Namespace="namespace.webserviceName" %> with webForm page.
One more issue popped up while I was trying to connect to the service with TLS/SSL protocols using asp.net 4.0.The Exception I received was: "The request was aborted: Could not create SSL/TLS secure channel"
-To solve this refer to this question answer
I have created a WCF Service and published it to a Windows Server running IIS. In an asp.net web application, I can add a Service Reference to the WCF Service which exposes its methods which I can call. This all works fine.
I need someone who is running a jsp site to be able to call a method in my WCF Service. How can they do that? (I know absolutely nothing about jsp). Presumably they cannot reference my WCF Service within their application in the same way you can within a .net application.
The web services are totally platform independent. Therefore, someone writing in Java should have no problem calling a web service server, regardless if it was written using WCF or another platform. For example, here, here and here you could find some tutorials on how to build web service clients using java. This java code could be called from JSP pages.
If you want to quickly test your web service from the client side, you could use SoapUI. It's a web service client tool developed in java. I am sure you will find it useful.
Hope I helped!
We have an ASP.NET 2.0 site. A 3rd party has created a web service that we are supposed to connect to, and I was naively expecting a 2.0 style web service to be created. When I was given the url, I was expecting to see a .asmx suffix...but instead was given a url with .svc suffix.
Going to that page tells me to to create a WCF client by running svcutil...but, again, we aren't running .NET 3.0+ yet.
Since it's a web service, I'm thinking the basic functionality should be essentially the same, but freely admit I know essentially nothing about WCF (yet.)
Can I expect this to work eventually, or is there some kind of potentially blocking issue (WCF web services being inherently different in some profound way)? Is there a simple path for creating a basic client (like svcutil would if we were in the 3.0+ world)?
If it's using BasicHttpBinding (SOAP 1.1) it's probably interoperable.
In the "Add Service Reference" dialog in VS2010, click on "Advanced", then click on the "Add Web Reference" button.
I'm trying to consume a WSE enabled Web Service from an ASP.NET Web Site.
I've installed WSE 3.0, used the config tool to add WSE info to my web.config and then done an Add Web Reference.
I believe that the problem may be that this is a Web SITE, not a Web APPLICATION. As such, the proxy class is generated at runtime, perhaps not adding the WSE magic.
I can access the proxy class from metadata, and it's of type System.Web.Services.Protocols.SoapHttpClientProtocol, which as far as I can tell doesn't have any WSE functionality.
I realize that this is all old technology, but I don't get to decide what the servers run :(
Any help would be greatly appreciated
You are wrong, proxy is generated when you are adding web reference.
Could you tell me how you are adding web reference to the website.
Please refer following article - http://msdn.microsoft.com/en-us/library/5sds7a0b.aspx
After you have located a Web service
for your application to access by
using the Add Web Reference dialog
box, clicking the Add Reference
button will instruct Visual Studio to
download the service description to
the local machine and then generate a
proxy class for the chosen Web
service. The proxy class will
contain methods for calling each
exposed Web service method both
synchronously and asynchronously. This
class is contained in the local .wsdl
file's code-behind file. For more
information, see Web References in
Visual Studio and Add Web Reference
Dialog Box.
Please refer following article - How to Add a Web Reference
Im trying to make a webservice in ASP.NET and get the data in a Smart Device Application.
I have the standard HelloWorld webservice and i wanna get the data in my application, but when i try to add a web reference to my project, Visual Studio can't find any webservices running. If i start the WebService in the WebService project and copy/paste the url to the "Add WebReference" in the Application project, Visual Studio finds the Webservice and i can use the InttilSence to find the HelloWorld Method (WebServiceClass.HelloWorld()) in the WebService. But when i then run the Application project the complier gives an error saying that it can't connect to the WebService.
How do i do this? How do i access a webservice in an Application project? Every tutorial or book i have read about the subject doesn't tell anything about how the webservice should i run. In my world the webservice project should be running before i can access it from another project or am i wrong?
Consider reading Rick Strahl's Creating Web Services with .NET and Visual Studio.
From there, you'll get the basics. You can build and deploy your XML SOAP web service.
Then you'll need to have your application use that web service as a 'Web Reference'. Start by "Add Web Reference".
(source: usaepay.com)
First, you should publish the web service to some server (even your own local IIS) rather than using the Visual Studio web server.
Then in your application, point to the correct URL wherever you published it when adding the reference.
While this is a bit low-tech, couldn't you create a web requrest from the Smart Device Application to hit the webservice directly? That would be my suggestion.
An example would be using the "WebRequest" Class.
It sounds like when you try to access the Web Service from your app, the service is not running (possibly because you're only running it in the Cassini server?).
The fact that you were able to generate the Web Reference means that at some point, the service was running and was able to generate the helper classes by examining the service.
I would do as David Stratton suggests and publish it somewhere where it can run while you are developing the Smart Device app (like your local IIS).
You might also take the opportunity to wrap the service call with some error handling - maybe catch the specific exception being thrown (System.Net.WebException?)
