I have a WSDL url(http:localhost:8080/userdata?wsdl) and I want to create a request to this webservice so I can fetch the data for further processing. Can I do this without wsimport?
If I have to create package from wsimport, how I can create a client which will use generated classes to create the XML request?
If I can do this without wsimport , how I can create a client which will create the XML request?
New to webservices, links to documentation would be appreciated. I am trying to understand this at the moment http://java.dzone.com/news/5-techniques-create-web-servic
You can use CXF wsdl2Java to generate a client code for the web service.
Once you run the wsdl2java , you will get a set of java classes generated for you. You can then use those classes to call the services without any explicit conversion of XML - the underlying framework will do it for you automatically. You can start with http://cxf.apache.org/docs/how-do-i-develop-a-client.html
I proposed CXF while you can look for many other alternatives - However, i have found CXF to be very feature rich and will help you in developing/working with web services.
On top of what Akhilesh said you can also create a Dynamic client for invoking WSDL. I have done it recently and i found it a little bit better then using CXF as dynamic client does not generate any code whatsoever. You just pass in the parameters to it and it does all the job for you. You can find a "shell" to build your own client HERE

I want to write a java client to use some medical api. On there website they have uploaded a bunch of WSDL files and corresponding XSD files, along with documentation explaining the SOAP messages format to consume each service.
In past I have used REST API of Amazon and Azure to write java client but this seems to be different.
I have read about JAX-WS and also tried to create a dynamic web project in Eclipse using Tomcat but nothing working (https://wiki.eclipse.org/Creating_a_Java_Web_Service_Client).
Could some one explain me basic steps on how to write a simple java
client to **consume these WSDL and XSD files using SOAP messages** and
point me to really good tutorial where I can understand the underlying
concepts?
Till now:
I read about basic wsdl and xsd structure.
Tried to use Postman and SoapUI to make service call to these services.
But struggling to make first step towards making a simple java client project to interact with these services.
I would recommend you go check SAAJ API
I wanna create a web service client to send some XML data to other web service. Google for the solution for a while but can’t find the correct answer. Now I suffered problem is how to import the WSDL file or ws-addressing to the workspace (if necessary)?
When I used eclipse built-in method to create a web service client it will automatically create some source code (Tomcat v7.0 Apache Axis2). How to use it to connect to other service and should I fallow the XML schema?
Here is the example below
http://help.eclipse.org/luna/index.jsp?topic=%2Forg.eclipse.jst.ws.cxf.doc.user%2Ftasks%2Fcreate_client.html
When I used some source code that I search from internet. The code looks like create a XML by itself. How to I follow the XML schema according to this code?
Here is the example below Working Soap client example
Hopefully someone may give me some clues or more detail information.
Try to use Jaxb & jax-ws which enable to generate and client stub from your WSDL and all XSD dependencies (if reachable). You will have java beans for all objects that will be passed in arguments (ie Jaxb will handle the XML conversion).
you can also refer to this thread: Web service client given WSDL

I have to request a PHP page with 3 Parameters (e.g. www.test.com/index.php?name=mrTest&no=1&id=10001). I'm using WSDL2JAVA for other Services and am now wondering if it is possible to generate a similar Service for this case. This PHP page Returns an XML. I'm just consumer/client of the Service.
I could also make a simple request and then use JAXB to parse the XML but i would like to implement all my Services the same way.
So, does anybody has already implement a php page consumer using WSDL2JAVA?
Best regards
So from my understanding this is a simple PHP page not a SOAP service. Remember XML is just the protocol used in a SOAP service however a SOAP service consists out of a WSDL that is published describing operations and how to call those operations.
A simple PHP page even if it returns XML data is NOT a SOAP service and thus does NOT have a WSDL. You wont be able to use WSDL2JAVA for that.
This PHP page seems more like a REST type service that returns XML instead of JSON. To be honest it really sounds like a REST service.
Try using the latest SOAPUI to connect to the page and see if you can use the REST project type with this page. If it is a REST service it might have a WADL file. YOu can use the WADL2JAVA cxf utility to generate classes to you. HOwever this is a BIG might as most REST services dont use WADL's yet. See this link on CXF
I'm writing a bridge between two old application on our network. One has a webservice that takes URL encoded parameters (GET) and returns an XML document. Like this:
http://mytest.com/getData/?format=xml&dateStart=2012-01-01
My question is this - I can use the XSD for the xml returned and marshall it into Java objects (xjc defined).. but is there any way to map the requests/responses to a jax-ws webservice (or similar?) It's not SOAP - so I can't go the WSDL, CXF/JAX-WS route, can I?
I was really hoping for an elegant solution to this without having to code it all from scratch (URL request , returned stream, then marshal). Is there a framework out there that would allow me configure a request? I thought WSDL supported verb="GET" but sadly, I can't seem to get it working with Apache CXF and WSDL2JAVA.
Am I totally off base here?
I think JAX-RS may be of use here. Just create XSD schemas and convert them to Java classes, and use a REST client for that site.
You can probably do it with CXF too. See here.
Check out WSGen or you can add ?WSDL to the end of your JAX-WS endpoint to get the generated WSDL. This way all you have to do is create your JAX-WS annotated classes similar to your JAX-RS ones and the WSDL is generated and it should be able to handle your XJC generated objects with no problems.

I wrote a java web service on Netbeans 6.9.1 and deployed on GlassFish 3.0.1
I have a wsdl url like this "http://localhost:8080/web2/service2Service?wsdl".
How can I use this url to access this web service from another java application.
Thanks
You need to generate some Java that represents the client's view of the Web Service and then invoke that Java. Here's an article which explains some of the detail.
Generating client from WSDL in Eclipse
The general idea is that you generate some Java classes from the WSDL. Those classes act as a proxy for the service you want to call. Your java invokes methods on the proxy objects, the generated code creates the appropriate SOAP messages, sends the HTTP request, interprets the response and your code just sees a Java result.
I just use the tooling built into Eclipse, but you will also find other suitable generators, for example in Apache's Axis
1º U must save the content in a "myWebServices.wsdl" file
2º Run your Wsdl converter, all compilers have one of this, normally the name is WDSL.EXE
This process will create a new file with NameSpace or Package with the definitions of webservices built in.
3º Then imports this package or built a library.
Develop web service Client in second application.
You can use Netbeans to create web service client by giving your wsdl url
The document at this url is the actual wsdl (a description of the actual webservice, written in WebService Definfition Language).
The description includes information about the services url, the protocol(s), the method names and and data objects. Your application will use that information to call the remote methods of that service.
The protocol may or may not be SOAP, and without knowing the webservice details, it's quite impossible to recommend a toolset or methodology to use the webservice, there is no general approach. In most cases we see SOAP, for those services I recomment soapUI as a general tool to use and test SOAP based webservices and apache axis to implement java based service consumers.
