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.

I need to consume a web service in java/jsp code. Only the WSDL is available for me to start.
I understand I need to convert the WSDL into java client JAR file using AXIS2 / CXF but I cannot build the whole application on this.
Can someone provide a simple example or basic steps for me to start on this?
I am not able to join the dots here. WSDL, java client JAR, AXIS2.... All online tutorials point on 'creating' a web service.
There are a number of tools capable of doing this included in various frameworks and app servers (CXF, JBoss/Wildfly, etc.), but the JDK itself includes a tool called wsimport which can consume a WSDL file and produce the JAX-WS stubs you need to remotely-invoke the service endpoints via a Java client.
Here's one quick description: http://www.mkyong.com/webservices/jax-ws/jax-ws-wsimport-tool-example/; here is the Oracle documentation for the tool in JDK 7: http://docs.oracle.com/javase/7/docs/technotes/tools/share/wsimport.html.
WSDL is just the conract for the web service. You need to generate client code using it, later you can implement your code to call the web service. Like #maerics pointed out, you should use wsdl2java to generate your client code for AXIS2 and use your client to consume the web service.
You can check this link for an example of client stub generation for AXIS2.
I have created a Web Service to add two numbers and I have designed the wsdl first and then accordingly with cxf tools wsdl2java I have created the server and client and it is running successfully , Please advise and share some url which can guide how to achieve the same thing with spring in cxf 2 , using wsdl first approach.
Using Apache CXF is quite simple and very easy to integrate with Spring.
This link provides all you need to create a service and client with Spring.

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.
Can any one provide me code for consuming webservices via SOAP in java? Actually i am able to consume webservices through HTTP GET and HTTP POST but my requirement is to consume webservices through SOAP.I tried through SOAP but not getting any output. So plz help me to out from this crisis.
Thanks
The WSDL is here:

You can view my example web service client on github. I use the maven cxf-codegen-plugin (as configured in pom.xml) to generate the client code, which is located here. You can then call the web service operations as demonstrated here.
If you search in google for java soap client example then you will find a lot of java examples of SOAP implementation.
If you have the WSDL of the web service, you can generate a Java client to talk to that service easily with Axis2 CodeGen
I need to call Java web service from .Net application and that web service should accept the parameters from .Net but am not sure about the procedure. If anyone have some idea then please let me know.
.NET web service is SOAP web service. Just get WSDL, generate stubs and use it.
You should get the WSDL first, then using Eclipse (I would suggest Netbeans) you generate/create the Stubs and call the service. It is really nothing fancy at all. Once you have the WSDL the rest (how you generate the classes using Netbeans) is really covered a lot online.
