[Java] Creating a Web Service Client in Eclipse

Step-by-step:

1. New a Java Project, say WebServiceClientDemo, in Eclipse.
2. Select WebServiceClientDemo project, right click > New > Other... > Web Services > Web Service Client. Click next. 
3. Type http://localhost:5566/WebServiceDemo/services/HelloWorld?wsdl in service definition. Click finish. Eclipse will generate several Java classes for us. For example, the code of HelloWorld.java is
   

   /**
    * HelloWorld.java
    *
    * This file was auto-generated from WSDL
    * by the Apache Axis 1.4 Apr 22, 2006 (06:55:48 PDT) WSDL2Java emitter.
    */
   
   package demo;
   
   public interface HelloWorld extends java.rmi.Remote {
       public java.lang.String greeting(java.lang.String in0) throws java.rmi.RemoteException;
   }
   

4. New a Java class to call greeting() method - Main.java:
   

   package demo;
   
   public class Main {
       public static void main(String[] args) {
           try {
               HelloWorldService service = new HelloWorldServiceLocator();
               HelloWorld helloWorld = service.getHelloWorld();
               System.out.println(helloWorld.greeting("Plover"));
           }
           catch (Exception e) {
               e.printStackTrace();
           }
       }
   }
   

5. Run as Java Application. We should see the following message in Console:
   

   Hello World! Plover!
   

Enjoy!
