How can I create an Endpoint for a web service? I am a beginner to the web services world.
I have got the WSDL and I would like to create a web service based on that WSDL. I have used Apache CXF to generate client stubs. What would be the next steps to test it as a service?
How can I create EndPoints?
How can I mimic the WSDL soapbind address locally and test it?
Let me clarify the Question. Looks like there is confusion. Thanks #Buhake Sindi for point it out.
I have got the WSDL and generated the Client stubs by using Apache CXF Framework in Eclipse. I need to test the WebService client code whether its working or not. How to test this approach now? My WSDL URL is not working at this moment.
How to test my client stub(from generated Impl Class)?
Do I need to create any Endpoints to mimic the WSDL URL(which is not running now)?
Hope the Question is clear now...
You can test client code even without creating web service implementation also. Are you aware of SoapUI tool? Use that to import the wsdl to create a project.
It gives you the option to create a mock service also along with the request. You can run that mock service and test your client against that service without writing any service code. I use it for testing all the time. Also you can create Success, Failure, and Fault response to test different scenarios. Mock service will also show you the request received by the service. This feature works like a charm. Let me know if you need help in setting up mock service in SoapUI.
You may follow this link to get started:
http://www.soapui.org/Getting-Started/mock-services.html
You run wsdl2java from CXF to generate server-side stubs. Then you fill in the code in the stubs. Then you set up a service to deploy.
There is no mechanism I know if that will create mock services. What would you expect them to do?
See the samples from the CXF distribution, particularly the wsdl-first samples.
A better approach would be to use JMock to mock the client side SEI, and not try to come up with a dummy service.

I want to run some integration tests on a WSDL client application. Therefore I'd like to have the WSDL server (which is not in control of me) to response with the same xml response always.
How could I achieve this? Is there any tool out that offers a wsdl endpoint an can always return the same xml (which I then could take from my live logs)?
SOAPUI offers this functionality. I've used it before with ease.
Alternatively if you do not want to go through the hassle of converting the WSDL request to a meaningful response, take a look at services like mocky which simply echo back a payload.
Take a look at Soap-UI - it has the ability to mock web services exactly as you mentioned using just a wsdl. You can then decide which XML the mocked web service will return, and it will run as a server locally. Instead of pointing to the 'real' server you can then point to your own local endpoint in order to retreive the same response. More information available on my blog here
I have a WSDL that has a handful of methods that I want to test. I was wondering if there is a way to write service requests and send them directly to the WSDL through Java? I could then parse the response to validate the success of the tests. I know that you can do this through soap UI but the problem I have with this is that I want multiple people who use this service to be able to run these tests and not everyone is using the same version of Soap UI. They are also going to be data driven tests so I want to be able to handle large data sets in cvs/xls files through java automatically instead of manually.
Any advice on where to begin?
Thanks
1.) Generate your webservices stub classes from your WSDL with the tool of your joice (for example wsimport).
In the simplest way this looks like this:
wsimport.exe -d <Path2StoreGeneratedStubs> -s <Path2StoreSourceFiles> -keep <Path2YourWsdl>
2.) Use those classes from within your JUnit tests to directly talk with your webservice.
So for your JUnit youre basicially on the client-side of your webservice. You want to generate stub classes to allow you to talk to your webservice but instead of writing a nice client application you are just using those Stubs for TestCases (just pseudo...) like this:
#Test
public void testPingMethod(){
MyService service = new MyServiceImpl();
MyPingResponse res = service.ping();
Assert.assertNotNull(res);
}
So MyService/ MyPingResonse in this example would be generated from the WSDL while the (also just an example) of the Assert would verify your Webservice sends back a response fo this request.
If you never had to write client code i recomend you do a 5min. Tutorial on the topic since its pretty easy to use an existing webservice :)
I am doing a project using Java and BPEL. I successfully created webservices in Java and integrated them using BPEL. All i generated a single output WSDL file. Now, I have to use this output WSDL file in my application using SOAP communication. How can i do that? Is there any help out side for such scenarios? Walkthroughs are really appreciated..
Depending on the architecture of your application (Standard Java, Spring-based, ...) there might or not be a documented procedure to consume a SOAP-based webservice.
On the other hand, you're always free to pick a webservice development framework to handle that. For instance, you could pick either CXF or AXIS2 (I believe these are the two most popular frameworks for Java WebServices). Each of these frameworks provides a tool called "wsdl2java" that helps you generate client-side/server-side/both Java classes. Then, you can easily add those classes and the requireds libraries to your application.
Having used CXF in the past, It even does provide several way to consume a webservice
Generating the client-side classes
Using CXF dynamic client factory : basically, you'll retrieve an endpoint proxy from a factory object.
Hope that'll help
I start with SoapUI (or downloadable from sourceforge), that will let you consume the WSDL and fire off requests against your server. Typically I'm hitting someone else's webservice, and trying to figure out what the data looks like before I start wiring my code together, but in your case its just a verification that the services would be/are working.
Then, as #KHY said, you can automatically convert the wsdl into java with a wsdl2java and start coding (look under the Related list on the right panel of this SO screen)
If it is a Java application, then the easiest way to consume a service is using JAX-WS. It's really easy to create a Web service client from WSDL.
See this link
Once you deploy the BPEL project on server, then refer the WSDL with http://server:port/application/YourBPELProjectService?WSDL in the consuming application. You will need to write different client code based on the BPEL type - Synchronous, Asynchronous etc.
I need to prototype a very simple system which sends a request to a remote web service, which will then callback on my own web service once it's finished processing. Unfortunately, I have to implement their WSDL for the callback.
Is there a nice simple way of generating a JBoss application which will correctly implement the WSDL, and run some trivial java code?
I tried wsdl2java from Apache CXF, but that only gave me a standalone server, not a deployable one.
Does this tutorial help?
Have a look at Axis2.
Here are some tools that I have found to test web services consumers:
http://www.soapui.org/
https://wsunit.dev.java.net/
Are there any others? I would prefer testing frameworks that are written in Java or Python.
I have used soapui by a maven plugin. It can create junit-linke reports to be run and analysed like unit tests. This can be easily integrated in continious build, also with the free distribution of soapui.
I've used Web Service Studio.
Web Service Studio is a tool to invoke web methods interactively. The
user can provide a WSDL endpoint. On clicking button Get the tool
fetches the WSDL, generates .NET proxy from the WSDL and displays the
list of methods available. The user can choose any method and provide
the required input parameters. On clicking Invoke the SOAP request is
sent to the server and the response is parsed to display the return
value.
This tool is meant for web service implementers to test their web
services without having to write the client code. This could also be
used to access other web services whose WSDL endpoint is known.
Also the Web Services Explorer in Eclipse which comes as part of the Web Tools Platform.
Through UDDI and WSIL, other applications can discover WSDL documents
and bind with them to execute transactions or perform other business
processes. The Web Services Explorer allows you to explore, import,
and test WSDL documents.
The Grinder is right up your ally with both Java and Python, that handles most web services, (SOAP/REST/CORBA/RMI/JMS/EJB) etc.

You really need to be more specific: What is it that you want to test in your WS-consumer? That it calls the right WS? This looks a bit pointless - WS are a perfect place for mocking whatever may be called - without anything being called.
In order to test the consumer you'd otherwise be writing a Webservice that mocks the original, right? I'd suppose that the communication protocol that goes through the wire is not the clients domain - e.g. it's generated. So the only thing a WS-consumer's client sees is the interface. And there's nothing to test in an interface.
It might be that I completely misunderstood your question - please clarify if I did. I'll revise the answer then.
