I'm working on a WSDL application. But actually I didn't understand what makes the "?wsdl" parameter and what will I do with the returned XML. For example:
https://adwords.google.com/api/adwords/cm/v201309/CampaignService?wsdl
This URL returns and XML string but what will I do with this?
I can convert schema files to java classes using jaxb (xjc) but I didn't understand correctly how to use this WSDL?
Thanks for your answers.
WSDL(Web Services Description Language) is just a contract in the form of xml defining the web services. It contains the details of input and output params of webservices. It is used between client and server to define the interface of communication. It is analogous to a method signature in a programming language. But as it is used between hetrogenous systems so xml is used to describe it.
WSDL is a XML file which contains description of a SOAP web service. WSDL file contains details regarding XML request structure, XML response structure, Web service endpoint details, Web service URL etc.WSDL file is the single most important file of a SOAP web service. The owner of a web service provides WSDL file to the client and by using the WSDL file a client interacts with the service. By using the WSDL file a client can generate client side stubs and java classes to contact with the server. Java since its release 7 supports APIs to generate client side code from a WSDL file. WSDL is created at the time of creating the web service.
When you have that URL containing the WSDL,simply use a tool like SOAPUI and generate a SOAP message and invoke web service. Web service can contain one more input elements so in that case you need to provide input element in the SOAP message.
To invoke a web service you just need a WSDL URL , you already have that. Just use a tool like SOAPUI.
WSDL is the file describing your webservices.
Meta Information about your methods, etc.
Any Web Client should understand and use WSDL files to generates all methods needed to communicate with a Web Server.

I have a wsdl url http://www.webservicex.net/geoipservice.asmx?WSDL
now if i generate a java source code by
wsimport -keep http://www.webservicex.net/geoipservice.asmx?WSDL
Is it going to generate actual soap web service code or just a interface which can call web service ?
I have seen some videos on youtube and as far as i think it cannot generate the actual java source code of soap web service. Please correct me if i am wrong.
so suppose if i want to make changes in soap web service(written in java), the changes in the generated file will not serve the purpose.
May be my question seems very basic to you, but i was looking at an application code and got this confusion , so please answer my query.
The wsimport tool is used to parse an existing Web Services
Description Language (WSDL) file and generate required files (JAX-WS
portable artifacts) for web service client to access the published web
services.
wsimport generates and compile the web service artifacts needed to connect to the service. This utility does not generate the actual web service.
I know that this is an old question , but for the record if you want to generate the actual WebService from an existing WSDL file you should use wsimport sibling which called wsgen
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).
Our code calls a webservice to fetch some data. But the service provider's service is down most of the time. I have the response xml. Can some one help us with the easiest way to access the hardCoded response xml to our webservice client code. We use Java Axis Webservice. Can i host the webservice on my local machine? I have the wsdl and xsd's . Please help me how to host this service.. Or is there any simple way to access the response xml through axis webservice client..
There are many ways available to create web service from wsdl. If you want to create it manually then you follow these steps
The most easiest way is to use some tools that can generate the webservice for you as Netbeans has a wizard which can create the webservice from wsdl. All methods and neccessary files generates automatically. see Developing Webservices from wsdl using Netbeans
After creating webservice you can host it from your local machine. Netbeans also has the option to run and deploy the webservice.
java -cp %AXISCLASSPATH% org.apache.wsdl.WSDL2Java http://wsdl_url
This will help you to generate the WebService from the WSDL.
I am using JAX-WS to export some SOAP Web Service Endpoints.
I know I can access the WSDL by appending ?WSDL to the web service endpoint. (Like http://localhost:8888/web_service/test?WSDL
Is there any other information I can get by appending things to the URL?
If you have a look at the generated WSDL (if you're using #WebService annotation) you can see that you can find the XSD with "?xsd=1".
I don't know how standard this is, though, and if there are cases where you could have different values than 1.
I want to build a web services client that takes wsdl link as the input and generates java classes. I know we can do this directly using Netbeans IDE where we provide the wsdl location during project setup. But I want the wsdl location to be provided when the client starts running. How do I do this?
Is the location that will be provided just used to specify the SOAP endpoint (for a web service whose WSDL was known at development time), or will it be a completely arbitrary WSDL?
In the first case, the web service client that was created by Netbeans has methods that accept an alternate SOAP endpoint URL. You can call those to use the client with a server whose location is not hard-coded in the client.
If however, the WSDL describes a completely unrelated service, how are you going to write Java code against it? You cannot use any interfaces derived from the WSDL (because they are not known at development time). You could only have a very generic SOAP client, where the user almost directly types in the XML that will be sent.
