Greetings young jedi,

Take this steps:

1. Read short but nice and clean WSDL tutorial on w3schools


2. Create CLIENT APP.

For this you will need any WSDL file that you can find
on any server that has WEB SERVICE SERVER SIDE

3. Use IDE (Eclipse, Netbeans) to automatically create client classes for you
directly from *.wsdl file

There is very nice little example on using Eclipse IDE for this here:
Use this key words to find it:
"eclipse web service create tutorial"


5. Create Test class using your 5 client classes
(In example below WebServerOperationsProxy is one of them)

Example:

/**
Call web serveice server, sending String param from client 
and getting some response 
*/
public class WebServiceClient {

	public static void main(String[] args) {

		WebServiceClient caller = new WebServiceClient();
		String s = "john";
		caller.callServer(s);
		
	}//

	private void callServer(String s) {

		WebServerOperationsProxy proxy = new WebServerOperationsProxy();

		try {
			String responseFromServer =  proxy.receiceResponseOperationFromServer(s);
			System.out.println(responseFromServer);
		} catch (RemoteException e) {
			e.printStackTrace();
		}

	}

If you have web service server up and running
on URL that is specified at LOCATION attribute at
the end of your *.wsdl file :

<wsdlsoap:address location="URL"/>

your client Test class will send String there through auto created proxy class
and you will get answer

Take your time, read all links i have posted
and you will be very satisfied with how quick you will have your on
example running

good luck young jedi!

Important HINT:

Every IDE, Eclipse for example has some sort of WSDL TEST tool.

No coding is needed to test if web service server is working !

If you have any J2EE Eclipse version with support of Web services in it:
1. copy *.wsdl file in your web project
2. right click on it and choose Web Services => Test with web service Explorer
3. In explorer first check URL of web service server
4. fill in all parameters needed to invoke server operation
(just like filling any form with proper data type)
5. call server
