I need to access a soap service and I have the wsdl url too. How would I go about doing this in java? Are there any good tutorials to achieve this?
Also I have an xml file generated in android to call a soap service but it isnt working. Is there any place I can paste this xml to check if the xml is correctly calling the webservice (I am using wireshark to record the xml being sent and it appears fine).
Regarding the first part of your question, you could use SoapUI ( http://www.soapui.org/ ) to load the WSDL and generate Java Client code for it ( http://nitinaggarwal.wordpress.com/2010/11/12/generating-client-java-code-for-wsdl-using-soap-ui-axis2-wsdl2java/ ). I used this way once but maybe there are better ways to do it.
The easiest is to generate a client webservice stub in netbeans. Simply create a new project and then add new web service client. Supply the WSDL and your done. Netbeans also has a great web service tutorial.
Very useful link: http://netbeans.org/kb/trails/web.html
I would suggest staying away from axis web service clients. My experience with axis is not great. wsimport used by netbeans is great so far. Uses JAX-WS.
You can use wsimport (part of JDK 6)
See documentation
CXF is both powerful and easy-to-use tool for Webservice Client Generation.
Axis does also ws client generation, but I personally had problems with it.

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!!!

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 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 using Apche Axis2 for a web service client. I know to get the output of a web service. But I want to get the soap Request and response from the wsdl file.
My wsdl is http://localhost:8080/getDetails?wsdl
It would be great if some can share their experiences.
Thanks in Advance.
If you want to use a software for that, use SoapUI.
If you want to do it from Java, you have these options.
Generate the classes for a SOAP Client using wsdl2java command.
There are many ways of doing this depends on the implementation you used.
Generate the classes for a SOAP Client using maven plugin, use this axistools-maven-plugin
After this search for a class having a name "...Locator" and "..PortType", use these classes.
OR,
Search for an Interface which has all the exposed methods and find a way to implement it.
Use SoapUI Tool , provide your WSDL path to this tool , it will load all operations from WSDL once if you click on perticular operation you can get sample SOAP request(XML payloads).
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 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.
