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 given a WSDL file. I need to call a SOAP web service in the WSDL. I would like to know the different ways of creating a web service clients from a WSDL in java. It would be helpful if the options are given with examples, links, pros and cons. I am now confused with different options like wsimport, wsdl2java, java2wsdl, saaj, apache axis, cxf, spring etc. Your help is much appreciated.
SoapUI doesn't support WSDL 2.0
You may try an experimental wsdl-generic library from Apache Taverna
The library works with both WSDL 1.1 / 2.0 versions.
The experimental branch creates XML tree based on Apache XML Schema 2.0 library, so you can easily create your XML message.
Then it dynamically calls the service via JAX-WS.
It also has a command-line WS executor!!!
Cheers,

I was working on a project using Salesforce SOAP API, and here is a link of the guide for using WSDL to generate java lib:
https://developer.salesforce.com/docs/atlas.en-us.api_meta.meta/api_meta/meta_quickstart_import_WSDLs.htm
Hope it will help you.
SoapUI is a quick solution with user interface to make initial tests for provided web service methods. Later you can use wsdl2java with specific options to generate Java classes from WSDL and make jar which you will include in your project.
I am using XFIRE to develop soap services .
what is the other best alternative to XFIRE .
I want to replace XFIRE code from other best approach beca
You can develop web services in different ways; Apache CXF is the successor of XFIRE so perhaps it's the easiest path; there is also a migration guide . You can also using Spring-ws, but it depends if you are already familiar with spring and if you want/can adopt Spring in your project. Spring web services are contract first i.e. You start from the wsdl (or xsd in you prefer) and write the code that handle the data incoming; you can read more about this here
Spring ws is very flexible and lets you handle the whole soap body allowing even to handle some ws client mistakes (in an ws implementation I handled two slightly different version of the ws with the same endpoint).
If you are writing web services, you are already using Spring and you are not afraid to manage the whole soap body you can choose Spring WS; if you want an easy migration path (because part of your team alreay knows xfire) apache cxf is the way to go.
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 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.
